Question

An astronomer observes an asteroid in the solar system. He notes that the asteroid is three times farther from the Sun than Earth is.

How far away from the Sun is the asteroid in astronomical units?
1 AU
2 AU
3 AU
4 AU

Answer 1

the asteroid is 3 astronomical units from the sun

Answer 2

The correct answer is 3AU

Step-by-step explanation

AU stands for Astronomical Unit that refers to the average distance between the Earth and the Sun, which is equivalent to approximately 150 million kilometers. This measurement is mainly used to measure distances within our solar system. According to the above, if the asteroid is three times farther the distance from the sun than Earth is, this is the same as being three astronomical units of the sun or 450 million kilometers as 1AU X 3 times = 3 AU or 450 million kilometers. So, the correct answer is 3AU
