 A The distance from the Earth to the Sun B The distance from the Earth to the Moon C The distance of the entire Solar System D None of the above
Explanation:

Detailed explanation-1: -Therefore, the planetâ€™s distance from the sun changes throughout the year. However, the average distance from Earth to the sun is about 93 million miles (150 million kilometers). Scientists also call this distance one astronomical unit (AU).

Detailed explanation-2: -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).

Detailed explanation-3: -The astronomical unit (AU) is the average distance from the Earth to the Sun, measured to be about 1.5 x 108 km (150, 000, 000 km) or 93, 000, 000 miles. It is a convenient unit to use when discussing distances within our solar system.

Detailed explanation-4: -The distance from Earth to the Sun is one astronomical unit (1 AU), which is 150 million km or 93 million miles.

Detailed explanation-5: -One astronomical unit (1 AU) is defined as the average distance between the Earth and the Sun so the Earth is 1 AU from the sun. This allows us to compare our distance to that of other planets like Mars (1.524 AU) and Venus (0.723 AU).
