Answer from: Hjackson24

The correct answer is D. 1 AU

Explanation:

In astronomy, the distance from Earth to the Sun that is also used to measure the distance from the sun to other planets or any other elements in the space is known as AU or Astronomical Unit, this covers around 150 million kilometers and is one of the most used units especially to describe the distance of objects in our solar system. This also implies 1AU refers to the distance of the Earth to the Sun; although the distance varies slightly depending on the position of the Earth in the orbit. Therefore, the unit that is closest to the distance of the Earth to the sun is 1 AU.

Answer from: gbprulesmile

1AU is the astronomical units closest to the distance of the earth to the sun.

Below is the mean distance from sun to each planet in Astronomical unit (AU)

Earth: 1.000 AU Jupiter: 5.203 AU Mercury: 0.387 AU Venus: 0.723 AU Uranus: 19.201 AU Neptune: 30.047 AU Mars: 1.524 AU Saturn: 9.582 AU Further Explanation

The Astronomical unit, AU is the means distance from the earth to the sun. Actually, the distances between from the earth and the sun varies and primarily depend on the time of the year. This is simply because the earth orbit within the sun is certainly not a perfect circle. The astronomical distance is about 93 million miles.

The distances within the solar system are measured in Astronomical units (AU). The innermost planet, mercury has a mean distance of approximately 0.4 AU to the sun. Also, Neptune, one of the known distant planets has a radius of approximately 30 AU. However, the parsec is used to express the distance the Interstellar and intergalactic.

The first month, January is the time that the earth is closest to the sun and far away from in July. In January the distance from the earth to the sun is about 0.983 AU and the mean or average distance from the earth to the sun is approximately 1.017 AU in July.
