Venus is almost the same size as Earth.
Earth's diameter is 7,926 miles (12,756 kilometers)
Venus's diameter is 7,257 miles (11,677 kilometers)
It has a volume of 9.38×1011 km3 and a mass of 4.868 X1024 kg
It has a surface area of 4.60 × 108 km2
It is about 0.9499 the size of Earth.

Venus, the second planet from the sun, is covered in clouds and has a very high surface temperature due to its greenhouse effect.
Due to an excess amount of carbon dioxide (CO2), its temperature is 460 degrees Celsius or 850 Fahrenheit or 735 Kelvin. It is the hottest planet.
It has a very thick atmosphere of Carbon dioxide that is considered a runaway greenhouse effect. Its average surface pressure due to the thick atmosphere is 93 bar, or 93 times that of Earth's. It is also the hottest planet.
The greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, the runaway greenhouse effect is causing temperatures high enough to melt lead. Venus lost its oceans due to its greenhouse effect.
On the Space Shuttle
The distance from Earth to Pluto is not constant, but averages to 3.57 billion miles. The Space Shuttle orbits at 17,500 miles per hour. Therefore 205,000 hours or 8,500 days or 23 years 105 days.
On the New Horizons probe
In January 2006, NASA launched the New Horizons probe on a mission to fly by Pluto. New Horizons is one of the fastest man-made objects ever launched, and is not scheduled to arrive at Pluto until July 2015 (it will not be entering orbit around Pluto. To do so it would have to slow down, significantly lengthening the travel time). So, as of now, it takes about 9.5 years to travel from the Earth to Pluto.
The Morning and Evening Star are a references to the planet Venus. Because it reflects the light from the sun so well it is usually the first "Star" that you see in evening and the last you see in the morning.
Although it is not a "Star", in ancient times they knew no different and so believed it to be one, and because it is so close to us its light (although only reflected from the sun) made it the brightest other visible object in the morning and evening sky, hence its name.
Confusingly, Mercury is also referred to in this way, for similar reasons.
Venus is scorched with a surface temperature of about 482° C (900° F). The surface pressure is 96 bars (compared with 1 bar for earth); the atmosphere of the planet consists of nearly all carbon dioxide (CO2).
Venus is closer to the sun than any other planet except Mercury. Its mean (average) distance from the sun is about 67 million miles (108 million kilometres).
Other interesting facts about Venus:
The diameter of Venus is about 7,520 miles (12,100 kilometers), approximately 400 miles (644 kilometers) smaller than that of the Earth. No other planet comes nearer to the Earth than Venus. At its closest approach, it is about 23.7 million miles (38.2 million kilometers) away. 108,208,930 km
The Earth's mantle is composed of rocks that have higher concentrations of mafic minerals (containing iron and magnesium) and lower in concentrations of the felsic minerals (aluminum and silica) than the rocks of Earth's crust.
The concentrations of the above elements therefore mean that the Earth's mantle is composed of a series of minerals that are predominately calcium / iron / magnesium aluminum silicates.
At depths shallower than approximately 460 km, these minerals form the rocks types Peridotite, Dunite (Olivine-rich Peridotite), and Eclogite.
At depths greater than 410 km Olivine becomes unstable and is replaced by a number of different mineral forms known as poly-morphs which are stable at higher pressures. These include Wadsleyite which forms at depths between 410 and 520 km and Ringwoodite which forms between 520 and 600 km deep.
These depths are based on a number of seismic discontinuities at the depths of 410 km (thought to mark the transition from Olivine to Wadsleyite) and at 520 km (thought to mark the transition from Wadsleyite to Ringwoodite) respectively.
At depths greater than around 650 km these upper mantle minerals start to become unstable due to the increased pressure and the minerals below this take the structure of the minerals Perovskite and Ferropericlase although with differing chemical compositions and it is this seismic discontinuity at 650 km depth that marks the transition to the lower mantle. The material at these depths is often referred to as the "post-perovskite" phase which is the high-pressure form of magnesium silicate (MgSiO3).

The diameter of Venus is about 12103.6 kilometers or 7520.8 miles.
The very slow (clockwise) spin of the planet means that there is no appreciable equatorial "bulge" as is created on Earth and the other planets. The radius of the planet is relatively uniform at approximately 3760 miles.
(see related question)
The average temperature on Venus is about 464 °C (867°F).
It is this hot because it is the second planet from the sun, and has what scientists call a 'runaway greenhouse' effect. A thick layer of clouds (carbon dioxide and some sulfuric acid) covers the surface and traps infrared radiation, raising the surface temperature of the planet.
The movement of the atmosphere gives the entire planet a nearly uniform temperature all year long, even at the poles and even at night. 900 degrees Fahrenheit The temperature at the surface of Venus is 740 K (467 °C, 872 °F). 750 to 930 degrees Fahrenheit (398 to 498 Celsius).
The temperature doesn't vary much on the planet.The averagevalue is about 460 degrees Celsius.
The distance between Venus and Earth varies depending on where the two planets are in their orbits. At their closest, the gap between them is 38 million kilometers, and at their furthest, 261 million kilometers.
It varies by the orbital position of the two planets. The average is about 26 million miles and the closest is about 24 million miles.
Earth's orbit averages 149 million kilometers (93 million miles) from the Sun.
Venus has an orbit of about 108 million kilometers (67 million miles) from the Sun.
The closest approach of about 39.5 million kilometers (23.6 million miles) would be with Venus at its farthest from the Sun and Earth at its closest. This is a rare occurrence.
When Venus lies between the Earth and the Sun, a position known as "inferior conjunction", it makes the closest approach to Earth of any planet, lying at a distance of 41 million km during inferior conjunction.
At 'superior conjunction' (when Venus is on the opposite side of the Sun and not visible to us) she is about 264 million kilometers from the Earth.
As with all planets Venus' orbit is slightly elliptical, at the closest point (Perihelion) Venus is 107,476,259 KM from the Sun, at the farthest point (Aphelion) it is 108,942,109 KM from the Sun.
On average Venus is approximately 67.2 million miles or 108.2 million kilometers away from the Sun.
In other units, it would be 0.723 AU or 6.01 light minutes or 0.0000114 light years.
Mean distance of 108,208,930 km
Maximum Distance 108,942,109 km
Minimum Distance 107,476,259 km
Venus does not have any moons or rings. The only other planet in our Solar System without a moon is Mercury.
According to NASA Venus has no moons.
Unlikely. Although numerous probes have (semi) successfully landed on Venus and reported back thanks to the Russians and there have also been numerous fly-by and orbital missions by the Americans and Russians; it is extremely doubtful that humans will ever travel to Venus to orbit let alone land there in our lifetime (and probably wont even in the lifetime of our grandchildren).
A manned Venus flyby mission, using cannibalised hardware from the Apollo program was mooted during the end of the 1960's and was planned to launch in late 1973 using a Saturn V to propel 3 men past Venus in a flight lasting approximately a year. Once it was sensibly argued that there is little or no point sending humans to merely orbit anyway (as any work like this can easily be done remotely and a human mission actually hinders things due to cost, size, distance etc.) the plans were shelved permanently.
Although Venus is often referred to as our "sister planet", it is quite an ugly sister. Venus is covered by clouds of sulfuric gas and sulfuric acid droplets and it has the densest atmosphere in the solar system largely comprised of Carbon Dioxide which is partially responsible for the runaway greenhouse effect of the planet (Venus is home to the strongest greenhouse effect in the solar system). This CO2 rich atmosphere coupled with deadly clouds of acidic sulfur dioxide helps create surface temperatures of over 460 °C (860 °F) and a Venusian planet surface actually hotter than that of Mercury. Furthermore, the atmospheric pressure on the surface of Venus is 92 times stronger than that on the surface of Earth meaning an exceptionally strong suit (and indeed landing craft) would need to be worn by any astronaut to avoid being crushed into the size of a sixpence. Venus's relatively small magnetosphere provides very little protection from the suns cosmic radiation thus adding further problems for any space tourists.
In a nutshell, visiting the surface of Venus is roughly equivalent to visiting hell and the required technology to do so and combat these formidable challenges within the confines of any likely mission objectives is currently beyond our reach.
No. One revolution of Earth is one year. One rotation, relative to the distant stars, is a sidereal day, and is about 23 hours and 56 minutes. One rotation, relative to the sun, is a solar day, and its average value is 24 hours.
Revolution is defined as the period a moon or planet takes traveling around another planet or sun. Rotation is defined as the period a moon or planet takes spinning around its own axis.
No signs of life of any sort have been found on Venus, or any other place outside of the Earth.
First Venus does not have a strong magnetic field of the same type as the Earth. The Earth N-S fields are created by the flow of liquid metal in the Earth's core. Venus has a very weak magnetic tendency produced by lightning in the upper clouds. As weather related effect that magnetism is high subject to change or disappearance. All known magnetic fields have both north and south poles as pairs of opposites. (Monopoles are still SciFi theory.) Properly speaking a compass points to both North and South with the opposite ends of the magnetic needle inside. By tradition, we simply choose only to mark and talk about the North end, ignoring the South end. Effectively the north and south fields flow from one to the other and "cancel" each other out at any good distance. Magnetism is only observed when you are inside that N-S flowing field. However for large objects the "Strength" of one or both poles may be spread around a larger area as multiple weaker minipoles. Thus a planet potentially could have one strong and easily recognized single location North or South pole and then a difficult to pin down opposite pole.
Venus has perpetual very thick cloud layers, so on the surface there would be no visible sunrise.
If the clouds were somehow removed, then there would be a sunrise, but because Venus rotates so slowly (and in the wrong direction) it would be a bit different than an Earthly sunrise.
Some facts about Venus:
The brightest of all planets, Venus, is also known as the Morning Star and the Evening Star. This planet is about the same size as Earth but is covered with impenetrable clouds of carbon dioxide and sulfur compounds. Radar mapping of the planet shows lots of craters and that 90% of the landforms are volcanic. Venus spins slowly retrograde (backwards, east to west) in 243 days and takes about 225 days to orbit the sun. This makes the solar day last about 117 Earth days. While it is bright there, the Sun is never visible from the surface. The "greenhouse effect" of the atmosphere traps and distributes the heat, so that the whole planet has a surface temperature of 450° to 464° C. The pressure at the surface is more than 90 times the sea-level atmospheric pressure on Earth.
Venus is the brightest planet on the sky
Venus rotates in the opposite direction to all the other planets, except
for Uranus. Also its rotation is the slowest of all the planets.
Venus has the highest temperatures found on any planet in our solar system.
This partly due to its very dense carbon dioxide atmosphere.
The atmosphere contains clouds of sulfuric acid.

Near the surface: Sulphuric Acid vapor. For most of the atmosphere above the surface: Carbon Dioxide.
You can determine your payback time by using your energy bills from the last 12 months. First look at three months during the summer, say June, July, August. Add the 3 months gas bills then divide this by 3. This gives you a average per month amount for the appliances other than the furnace since you do not use the furnace in the summer. Next multiply this average per month number by 12. This is how much you spent on gas for the whole year on every appliance except the furnace. Now add up the 12 months total gas bills and subtract the amount that you figured above for the 12 months of other appliances. This gives you an accurate amount that you spent on just the furnace in gas for an entire year. Now if your furnace is 40 years old it probably has an efficiency rating of 60% AFUE. That means about 60 cents out of every dollar spent on the furnace gas heats the house and 40 cents goes up the chimney. The new high efficiency furnaces are 95% efficient so only 5 cents out of every dollar is wasted out the vent. You can now get bids on new furnaces to check your payback. Say the new furnace costs $2600.00, you can see our local furnace prices at http://www.woodburyheating.com . At the $2600.00 example you can use this to determine the payback. Let us assume a energy bill to use as an example. Say your last years gas bill for just the furnace that you calculated above was $2250.00. This may be a common amount in Minnesota. 95% is 35% more efficient than 60%. $2250.00 multiplied by 35% is $787.50 per year in savings. Using this example the payback would be $2600.00 divided by $787.50 which is 3.30 or about 3 and 1/3 years. Do not forget to take into account the old furnace may break down and the payback would be quicker and how much is peace of mind worth? == == == == guestimating solely on basis of average sear ratings then and now, about two or three years. payback starts as soon as you fire up furnace and go so sleep or leave the house since all new fau's are 100% safer than even a 20 year old unit but if you still have a forty year old unit please use a carbonmonoxide detector. With the new 15 seer units the payback would be approx. 8 years It all depends on the SEER of the unit, size of unit, brand of unit, gas price, etc... But, I would say around 5-8 years. You couldn't know the answer without knowing what your average seasonal temperatures and utility costs are. But consider this. If that forty year old unit breaks in the middle of a cold winter, it's unlikely you'll get the best price. In other words, cheap is expensive. if you take a 60% gas furnace and your gas bill is about 250.00 mth and you replace your furnace with a 92% you will save anywhere around 50.00 to 75.00 per mth also 92% furnaces have a sealed burner section and a lot more safety devices witch makes them one of the safest means of heat out there If your current furnace is 40years old, you have already collected the payback...
Because Venus's spin is retrograde, that is to say it spins "backwards". (Also it travels around the sun faster than it spins on its axis, meaning the Venusian "day" is longer than a Venusian "year".) That is the Venusian SIDEREAL day which is its rotation period.
The SOLAR day is how long the Sun takes to apparently travel once round the sky.
That's from one Venusian "noon" to the next.
The combination of retrograde spin and very slow spin causes the Solar day
to be much less than the time taken to spin once (the sidereal day).
On Earth the solar day is more than the sidereal day, but not by much.
