The Astronomical Unit, or AU, is an important way to measure distances in our solar system. It tells us how far the Earth is from the Sun, which is about 93 million miles (or 150 million kilometers).
Distance Reference: The AU is like a standard ruler for measuring how far away other planets are. For example, Mars is about 1.5 AUs from the Sun.
Scaling the Solar System: Astronomers use the AU to explain how big our solar system is. For instance, Jupiter is around 5.2 AUs away from the Sun.
Easier Comparisons: Space distances can be really huge and hard to picture. Using AUs makes it simpler to compare how far apart different planets are.
Overall, the AU helps astronomers see and understand the space around us better.
