Uranus's moon Ariel was discovered in 1851. The moon was discovered along with Umbriel, another moon of the planet, by William Lassell.
The atmosphere on Mars is 95.72% Carbon Dioxide.
Is gravity on earth greater or less then gravity on mercury?
The gravity on Earth is stronger than the gravity on Mercury.
How long does it take charon to orbit Pluto?
Charon takes around 6.4 Earth days to complete one orbit around Pluto. It is tidally locked with Pluto, meaning that one side always faces the planet.
How many days are there in Venus in 1 year?
The rotational period of Venus is not the same as its solar day. It takes about 243 Earth days for Venus to make one slow spin, and it is in the opposite (retrograde) direction from its orbit. It can be said to spin clockwise, or east to west.
At the same time, it takes only 224.7 Earth days for Venus to orbit the Sun (its year). So the "day" on Venus is actually longer than the year!
(1 Venus year = 0.925 Venus sidereal day)
However
The result of these two motions produces a "solar day" (sunrise to sunrise) of about 116.75 Earth days on the planet, although obviously the sunrise cannot be seen from the surface.
(1 Venus year = 1.92 solar days)
Why is Venus the third brightest natural object in the sky?
Venus is the 3rd brightest object in the sky, after the Sun and the Moon, because its thick atmosphere is so hot that it is actually radiant (it gives off light, not just reflecting sunlight like the Moon does). It is hotter than Mercury, even though Venus is farther from the sun than Mercury. Venus gives off so much light, in fact, that it is possible to see the planet with the naked eye even during daylight.
Appears when Venus is seen in the evening twilight of the western sky?
Venus is commonly known as the "evening star" when it is visible in the evening twilight of the western sky. This is because it is often the first bright object to appear in the sky after sunset. Venus can be seen shining brightly due to its reflective cloud cover.
Venus actually appears yellow, due to sulfuric acid and carbon dioxide clouds all over its surface.
However, when a photo is taken with an ultraviolet filter Venus does appear blue.
See related links for a picture of a blue Venus and a picture of Venus in real colour.
Which Venus or Pluto has longer orbit explain why?
Mercury orbits our sun at a much quicker rate than Pluto. It's orbital speed is quicker due to it's proximity to the sun and it has a much shorter path to complete. The further out a body is from the sun, the longer it takes to orbit.
What would happen to Earth if it moved 30 million km closer to Venus?
If Earth moved 30 million km closer to Venus, it would disrupt the delicate gravitational balance in our solar system. The increased gravitational pull from Venus could potentially lead to unstable orbits for both planets, causing disruptions in their respective atmospheres and possibly affecting life on Earth. Ultimately, the consequences would be catastrophic.
What is venus 's spin example of?
Venus has a slow retrograde rotation, meaning it spins in the opposite direction of most planets. The exact reason for this unique spin is not fully understood, but it may have been caused by a collision with a large object in the past.
Why spaceship visiting Venus are destroyed?
For one thing spaceships ain't real, but if the were they would be destroyed because Venus is too hot! It will destroy anything that lands on it.
Comments: Spacecraft from the USSR have landed on Venus. They were "real".
Some were destroyed by the atmospheric pressure before they landed. Some
landed, but were destroyed fairly quickly, probably by the heat.
How tall are the mountains on planet Venus?
Yes Venus does have mountains. It has valleys which make up the mountains, Venus' mountains aren't as big as ours but if we were to go there it would be quite huge. At the top, left of centre, [See Link] the bright region is Maxwell Montes, the highest mountain range on Venus. Its peak is 11 km above Venus's average surface elevation.
What is the polar diameter of Venus?
The planet Venus is slightly smaller than planet earth. It has a polar diameter of 12,102 kilometers. A Venusian day is equal to 243 earth days.
What is the order from the sun to Venus?
the first planet out of the nine planets and the closest planet to the sun is mercury.
First planet.
What causes Venus to appear so bright in the night sky?
Venus has an atmosphere of thick, swirling clouds. Which reflects light very well.
How hot is Venus on the dark side?
The dark side of Venus experiences temperatures exceeding 800 degrees Fahrenheit (427 degrees Celsius). This extreme heat is due to the dense atmosphere trapping heat from the nearby sun, creating a greenhouse effect on the planet.
Why is the rotation of Venus called retograde rotation?
Venus, as well as the Earth, has flipped on its axis several times in the past. This was caused when Venus' rotation around the sun encountered the Earth, the last time being approximately five million years ago. Though it now spins backwards, in the beginning of our solar system it spun just like the Earth.
Who is the living on the moon?
Astronauts!But if you look closely at the moon you might see the moon's face!Funny huh?Also if you are in the car you can also see the moon following you but it is not!
Why is Venus the coldest planet in space?
Venus is not the coldest planet in space; in fact, it is the hottest planet in our solar system. This is because of its thick atmosphere that traps heat, creating a runaway greenhouse effect. The surface temperatures on Venus can reach up to 900 degrees Fahrenheit (475 degrees Celsius).
What is the 3 features unique to Venus'?
What state is the surface of Venus?
Beneath the clouds that hide Venus from view, it is a fairly barren and unpleasant place. There are no bodies of water, no vegetation, no life.
The thick atmosphere is almost entirely carbon dioxide, at a crushing pressure 93 times as at sea level on Earth. The average temperature is 460°C (860° F, hot enough to melt lead) planet-wide and even at night, because this heat is carried around the planet. There is no oxygen and no liquid water, and only the smallest trace of water vapor.
Venus's surface is a dry, reddish, rocky desert with many slab-like rocks, and the lava plains are periodically refreshed by volcanism. Although there are innumerable volcanic landforms on the planet, only a small number of volcanoes are currently active. They tend to be short, no more than 1.5 kilometers (5000 feet) high, and generally wider than volcanoes found on Earth.

What is planet Venus's air made of?
Venus's atmosphere is composed mainly of carbon dioxide (96.5%) and contains small amounts of nitrogen and other gases. It also has thick clouds of sulfuric acid droplets, which contribute to its extremely high surface temperature and pressure.
