Where is the position of Venus in the sky?
The position of Venus in the sky varies depending on the time of year and time of day. Venus is visible in the early morning or evening, commonly appearing in the west after sunset or in the east before sunrise. Its position relative to the horizon changes throughout the year due to its orbit around the Sun.
What is the time of one rotation on its axis for Venus?
Venus rotates on its axis very slowly, taking about 243 Earth days to complete one rotation. This is longer than it takes for Venus to orbit the Sun, which is about 225 Earth days. Venus also rotates in the opposite direction to most other planets, a phenomenon known as retrograde rotation.
How long does it take for Venus to go around its own axis?
It takes about 243 Earth days for Venus to complete one rotation on its axis. This means that a day on Venus is longer than a year on Venus, as it only takes about 225 Earth days for Venus to complete one orbit around the Sun.
How much does venus weigh and earth weigh?
Venus has a mass of about 4.87 x 10^24 kg, and Earth has a mass of about 5.97 x 10^24 kg. Weight is the force exerted on an object due to gravity, so it depends on the mass and the acceleration due to gravity at that location.
How does the length of a day on the inner four contrast with the length of a day on the outer four?
The inner four terrestrial planets have shorter days compared to the outer four gas giants. This is because the inner planets rotate more quickly due to their smaller size and proximity to the sun, while the outer gas giants rotate more slowly because of their larger size and distance from the sun.
How far away from the sun is venus compared to earth in fractions?
Venus is 0.723AU from the sun. To convert this into fractions:
0.723 = 723/1000
If you round off the value from 0.723AU to 0.72AU, then the fraction would be:
720/1000 = 9/125
Have any robots or satellites explored venus close?
Yes, numerous space probes have explored Venus, including NASA's Magellan spacecraft and the Soviet Venera missions. These missions have provided valuable data on Venus' surface and atmosphere, giving us insights into its extreme conditions. However, no robots or satellites have been able to explore Venus up close in the same way as those on Mars due to its harsh environment.
What is the star next to Venus?
The star next to Venus is most likely the planet Jupiter. Venus and Jupiter are two of the brightest objects in the night sky and are often visible close to each other. Jupiter will appear as a bright point of light that is usually larger and not twinkling like a star.
Is human life possible on planet venus?
It has been scanned by orbiting space probes, so the terrain has been mapped. Other probes have also landed on the planet and taken pictures. It has been explored, but not directly by humans - no human has set foot on the planet.
What is Venus Sidereal period?
Venus has a sidereal period (orbital period relative to distant stars) of approximately 224.7 Earth days. This means it takes Venus about 224.7 days to complete one orbit around the Sun.
Is venus one of the biggest or smallest planet?
ONE of the smallest but brightest............same size as earth (about)
Would Venus be a popular tourist attractions?
Yes, Venus has unique characteristics such as its extreme heat and thick atmosphere that could make it an intriguing destination for space tourism in the future. However, challenges such as the harsh conditions and lack of a solid surface would make it difficult for humans to visit Venus at the present time.
How many hours in one day on venus?
The concept of a 24 hour day cannot be extended to Venus or Mercury as it is to Earth and Mars. On Earth, there is only a tiny difference between rotational time and solar time. On Venus, the difference between the sidereal day (243 Earth days) and the solar day (117 Earth days) makes clock times meaningless.
A rotational day on Venus takes about 5832 Earth hours. A sunrise-to-sunrise day takes about 2802 Earth hours. Using either to design a clock would not be practical. Even the defining characteristic of day and night are not important because radar is used to observe the surface beneath the clouds. There is also virtually no difference between day and night temperatures on the surface.
One concept that is used for time on Venus is the longitudinal noon, which establishes 360 divisions of rotational time to the 1.92 solar days that exist during the Venusian year (225 Earth days). Of course, the Sun would never actually be visible on the surface.
How do you memorize the phases of the moon?
Just remember that New Moon is the start, waxing means growing, waning is shrinking. This might be silly, but remember the word "relaxing". The letter R (and it rhymes with waxing) stands for growing on the RIGHT side.
New Moon
Waxing crescent
First quarter
waxing gibbous
Full Moon
Waning gibbous
Last quarter

How long would it take for a radio signal from earth to reach Venus?
It takes about 5 minutes for a radio signal to travel from Earth to Venus when they are closest to each other in their orbits. Venus is approximately 38 million kilometers away from Earth at its closest point.
Why is Venus easy to identify in the night sky?
Venus is easy to identify in the night sky because it is one of the brightest natural objects in the sky after the Moon. It can often be seen shining brightly shortly after sunset or before sunrise. Venus's brightness is due to its thick clouds reflecting sunlight.
Venus trophobia is a fear or avoidance of beautiful women. This phobia may stem from underlying issues related to social anxiety, self-esteem, or past negative experiences. Treatment may involve therapy to address underlying causes and cognitive-behavioral techniques to manage the fear.
What is t distance of the sun from venus?
On average, the distance between Venus and the sun is about 67 million miles (108 million kilometers). This distance can vary as both Venus and Earth have elliptical orbits around the sun.
That number depends on what it is associated to, it can basically be an expression in mathematics which shows a number is smaller then 1, in other words, 1>0.922 , that is how small the number really is.
How long would it take to get from Mercury to the Venus?
It's 77,248,512 km from Venus to Mercury. It would take you 386.24 hours or 16.09 whole days of 24 hours.
Where on Earth do you have to be to see Venus or any other planet through a telescope?
You can see Venus or other planets through a telescope from anywhere on Earth. The visibility of the planets depends on their current position in relation to Earth and the time of year. It is best to observe them from locations with minimal light pollution for optimal viewing.
Why are Mercury and Venus hotter than Earth?
Mercury and Venus are hotter than Earth due to their proximity to the Sun and their particular atmospheres. Venus has a thick atmosphere that traps heat from the Sun, creating a strong greenhouse effect. Mercury lacks a significant atmosphere, so its surface temperature varies greatly between its scorching daytime and freezing nighttime temperatures.
Why does venus have lower gravity than earth?
Venus has lower gravity than Earth because it has a smaller mass than Earth. Gravity is directly proportional to the mass of a planet, so planets with smaller masses will have lower gravitational forces.
Is it true that Venus' days are longer than its years?
The speed at which a planet rotates (spins) determines its "sidereal day", and the period of its orbit around the Sun determines its "year".
The "solar day" is determined by a combination of the spin time and the year.
The rotation of Venus is extremely slow, and it spins "backwards", from east to west (clockwise as seen from from above the Earth's north pole). The time Venus takes to complete a rotation (243 Earth days) is longer than the time it takes to orbit the Sun (225 Earth days). So a "sidereal day" is longer than its year.
However, the "solar day" is about 116.75 Earth days long. So, in that case, the year is about twice the day length. The solar day is shorter than the sidereal day because Venus rotates "backwards". Astronomers call this "retrograde rotation".
On Venus, the Sun (if it were visible) would rise in the west and set in the east. The combination of its rotation and revolution produces an apparent solar day (roughly sunrise to sunrise) of about 116.75 Earth days.
Venus is the only planet, apart from Uranus, that rotates in the clockwise direction. There are several theories why Venus rotates this way. Most involve a collision with another orbiting body in the distant past.
(Uranus's retrograde rotation is a result of the planet being tipped onto its side. Its axial tilt is 98 degrees, meaning its "north pole" is "below" the plane of the orbit. If its north pole was "above" its orbital plane (like the Earth's), it would be rotating "normally".)
