Planet Venus

There is liquid sulfuric acid in the upper cloud layers of Venus' atmosphere. It evaporates before it reaches the surface. There is no water to speak of, due to the temperature of 860 F. Some scientists think that water did exist several billion years ago, but it has long since boiled off in the runaway greenhouse effect of the atmosphere, which is 96.5% carbon dioxide and 3.5% nitrogen.

Venus has a diameter of about 12,104 kilometers, making it the second smallest planet in our solar system.

Venus is not the largest planet in our solar system. The largest planet is Jupiter, which is over 11 times wider than Venus. Venus is the second planet from the Sun and is similar in size to Earth.

As of 2021, there have been over 20 spacecraft missions that have visited Venus, including flybys, orbiters, and landers. Some notable spacecraft include the Venera probes launched by the Soviet Union, the Magellan spacecraft by NASA, and the Akatsuki probe launched by JAXA.

Several spacecraft have observed Venus, including NASA's Magellan spacecraft which mapped the planet's surface with radar, and the European Space Agency's Venus Express which studied the planet's atmosphere and surface. The Soviet Union's Venera program also sent several landers and probes to Venus in the 1970s and 1980s.

No, Venus is the second planet from the sun, located between Mercury and Earth.

The gravity present on a planet is usually denoted by the acceleration an object would experience due to gravity on that planet's surface. If we stick to Newtonian gravity (which should be adequate for our present purpose) the acceleration due to gravity on a planet is given by:

a = G*M / R^2

Where G is Newton's gravitational constant, M is the mass of the planet, and R is its radius (remember we are standing on the surface).

(Note: Here I have neglected the vector qualities of acceleration, this will not matter at present, the acceleration will be pointing down, towards the center of the planet.)

From this formula we can see that the acceleration increases if the mass of the planet increases. This is to be expected; gravity (in Newtonian gravity) is caused by mass, and thus a bigger mass means a stronger gravitational field. Since Venus is less massive than Earth we might expect the surface gravity on Venus to be less than on Earth.

However, we also have the R^2 in the denominator. This means the surface gravity on a planet will increase if the radius decreases (and the mass stays the same). This is also clear; if the radius is less then you stand deeper into the gravitational field. Venus is about the same size as Earth so this effect should not play as much a role as the difference in mass does.

Thus, just by using these arguments we can already conclude that the surface gravity on Earth is larger than the surface gravity on Venus.

Let us now look at some numbers. Earth's surface gravity is about 9.81 m/s^2 (it varies slightly from location to location). And Venus' surface gravity is 8.87 m/s^2, which is less, as expected.

This means that if you weigh 70 kg on Earth you will weigh 70*(8.87/9.81) = ~63 kg on Venus.

it takes 224.8 days for venus to orbit the sun venus is the closest planet to the earth and is 55 milion miles away from the sun it is the hottest planet in the solar system with a temperature of 896 degrees F.it is hotter then mercury because its atmosphere is all fire and volcanoes it has 0.002% water vapor and can not be travelled to by astronomers because if we went to venus we would die within 15 seconds for the devestatiing heat.

The weight of an object that is 100 pounds on Earth would be approximately 38 pounds on Mercury. This is because Mercury's gravity is about 38% that of Earth's, so the object would weigh less on Mercury.

The linear speed of Mercury in its orbit around the Sun varies, but on average, it is about 48 km/s. Mercury's speed is fastest when it is closest to the Sun (perihelion) and slowest when it is farthest from the Sun (aphelion) due to Kepler's laws of planetary motion.

Venus shines brightly because it has a highly reflective atmosphere made up mostly of carbon dioxide, which reflects sunlight extremely well. This, combined with its proximity to Earth and its thick cloud cover, makes it one of the brightest objects in the sky after the Sun and the Moon.

Yes........and no.

There are two definitions of "day". The 243 Earth days is the rotation period

known as the sidereal day.

However there is also the "solar day". This depends on a planet's orbital

motion as well as its spin. That is only about 117 Earth days for Venus.

No, Venus has far more carbon dioxide. Earth's atmosphere is about .04% carbon dioxide. By contrast, Venus has an atmosphere that is 96% carbon dioxide and 93 times thicker than earth's. This means that Venus' atmosphere contains over 200,000 times more CO2 than earth's atmosphere does.

Venus has been explored by spacecraft such as the Russian Venera missions and the more recent European Space Agency's Venus Express mission. These missions have provided valuable data on Venus's atmosphere, surface features, and geology, helping scientists understand the planet's extreme conditions. Future missions, such as NASA's proposed VERITAS and DAVINCI+, aim to further study Venus's geological processes and atmospheric composition.

Galileo discovered, in his observations of the different phases of Venus, that Venus and the Earth were revolving around the Sun. This was contrary to the misconception at the time that everything revolved around the Earth.

Venus is the hottest planet and holds more gas than all the planets so Venus' color orange, brown and yellow i think was formed by lots of heat in its atmosphere that goes in the clouds and makes that color.

Yes, Venus has several unusual features, including its thick, toxic atmosphere composed mainly of carbon dioxide, its extremely high surface temperatures due to a runaway greenhouse effect, and its retrograde rotation, where it spins in the opposite direction compared to most planets.

Venus rotates on its axis in the opposite direction to most other planets, a phenomenon known as retrograde rotation. This means that the Sun rises in the west and sets in the east on Venus. Additionally, Venus has an extremely slow rotational speed, with a day on Venus lasting longer than a year on the planet.

A planet seen close to the Sun at dawn or dusk is sometimes called the Morning Star or Evening Star.

In the context of medieval weaponry, the Morning Star resembles a combination mace/spiked club. It could be either a foot soldier's or mounted soldier's weapon. In the simplest terms, it was a wooden-handled weapon (betweeen 2 and 4 feet long), with a metal end. This metal end was usually an iron cylinder, which had roughly a dozen or more 4-inch iron spikes protruding out perpendicular to the shaft, plus usually a long spike at the end (typically 6 inches in length). It is different from a mace, in that a mace's head was usually a forged ball or cylinder with metal studs or short (1-2 inch) flanges cast as a single piece (i.e. the flanges or studs were not added later). It differs from a spiked club in that the spiked club did not have the protective metal cylinder at the head end.

About 10% less than you do on Earth.

Venus is approximately 108 million kilometers away from the Sun on average.

== == While the temperature and pressure on the surface are far just too great for colonization, there is an area 50km above the surface where the temperature and pressure are Earth-like, the winds circle the planet in 100-hour "days", and the gravity is just less than earth-like. Because the gases there are heavier than Earth's atmosphere, there is the possibility of "floating cities" kept in place and following the prevailing winds much like present day hot air balloons.

Your bubble wouldn't need to be incredibly strong, but it would need to be resistant to sulfuric acid. And you would need oxygen and food starting with materials shipped form Earth. In return, you could use abundant solar energy and sulfuric acid as resources for your own industries.

Venus does not have any moons. It is one of the only two planets in our solar system that do not have any natural satellites orbiting around it.

Yes, Venus has a rocky composition similar to Earth, with a dense atmosphere mainly composed of carbon dioxide. It also has traces of sulfuric acid clouds and volcanic activity that contribute to its extreme surface temperatures and pressure.
