Question

A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent

Answer 1

300 billion kilometers represents 2005.37613668053 AU

Answer 2

Answer: 2005,37 AU

Explanation: 1 AU in KM = 149,598,000 kilometers

An astronomical unit is a method that astronomers use to measure large distances in the Solar System. 1 astronomical unit, or 1 au, is the average distance from the Sun to the Earth.

The Earth’s orbit around the Sun is actually elliptical. It varies from 147 million km to 152 million km. So the measurement of an astronomical unit is just the Earth’s average distance from the Sun. That’s where the more precise measurement of 1 AU to KM (149,598,000 km) comes from.

In this case:

300,000,000,000 KM ÷ 149,598,000  KM = 2005,37 AU
