0.4 astronomical units From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 3.2 minutes to travel from the Sun to Mercury.
What planet is 19.22 AU away from the Sun?
Uranus The average distance of Uranus from the Sun is 19.22 AU. We can also use this as its rough average distance from Earth.
What is the measure of AU?
astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
How many Aus from the Sun is Earth?
1 AU As noted earlier, Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. That's 1 AU.

How are astronomical units calculated?
For general reference, we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km). It's approximately 8 light-minutes. More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km).
Who owns planet Mars?
Mars belongs to everybody, according to the Outer Space Treaty, which the United States signed back in 1967. The treaty says nobody can own a celestial body.
How long is a Martian year?
687 daysMars / Orbital period The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
How do you convert AU to km?

Can we land on Mercury?
Could humans land on Mercury's surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet's surface. Mercury's slow rotation means it takes 59 Earth days for it to turn around once.
What does it rain on Mercury?
Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat).
