Question

Use the information in the passage to answer these two questions.

1. Why are astronomical units not commonly used to measure distances outside the solar system?
2. Why are light-years not usually used for distances within the solar system?

Answer 1

1. units smaller then light years, or astronomical units are too small to be used outside of the solar system. It’s hard to comprehend how far 10000000000000000000000000000000 kilometers or miles is.

2. Light years are usually not used for distances within the Solar System because the solar system is too small to use light years. There would be a lot of decimals.
