What is the difference between astronomical units and light years?
Can you explain the difference between astronomical units and light years?
Sure! Astronomical units (AU) are used to measure distances within our solar system, specifically the distance between the Earth and the Sun. One AU is about 93 million miles. On the other hand, light years (ly) are used to measure distances outside of our solar system. It is the distance that light travels in a vacuum in one year, which is about 5.88 trillion miles.
