What is Earth's average distance from the sun AU?

Answer 1

The moon is approximately 75 au's from the Earth

The above answer is absurd. One Astronomical Unit (AU) is the mean (average) distance from the Earth to the Sun. If that answer was correct, the Moon would have to be 75 times further from Earth than the Sun!

The average distance from the center of the Earth to the center of the Moon is 0.00256957366 AU or 384,403 kilometres (238,857 mi).

Answer 2

1 AU

The exact distance between Earth and the Sun varies with its position in its orbit, which is elliptical. The average distance (the mean distance) between the Earth and the Sun is about 150 million kilometers (93 million miles).

The average distance from the Earth to the Sun is also called 1 astronomical unit (or AU). This is established as 149, 597, 870.7 kilometers (92,955,887.6 miles).

• Aphelion (when the Earth is the farthest from the Sun) occurs around the first week of July. The distance is about 152 million km (94.4 million miles).
• Perihelion (when the Earth is closest to the Sun) occurs in the first week of January. The distance is about 147 million km (91.3 million miles)

Answer 3

That depends on the comet; every one is different. Comets follow extremely elliptical orbits, and may come within one-half an AU or closer - and then recede to 100 AU or more.

Halley's Comet is one of the shorter-period comets; it's farthest distance is 35 AU, with a perihelion of about 0.58 AU.

Answer 4

Earth's average distance from the sun is about 93 million miles or 150 million kilometers, which is approximately 1 astronomical unit (AU).

Answer 5

One AU. An astronomical unit (AU) is the average distance between the earth and sun.

Answer 6

The avg. would be the same as the Earth. 1 AU

Answer 7

The average sun to Earth distance is how one Astronomical Unit is defined (1 AU).

The distance of Earth to the sun varies throughout the year though, from 0.983 AU to 1.017 AU.

Answer 8

The mean (average) distance between earth and sun is the definition of 1 AU .

Answer 9

The "mean distance" from the Sun to the Earth is defined as being one astronomical unit, or AU.

Answer 10

0.7233 Au's away from the sun
