An Astronomical Unit (AU) is a way to measure distance in space. It is the average distance from Earth to the Sun, which is about 93 million miles, or around 150 million kilometers.
Standard Measurement: AUs make it easier to talk about distances in space. Space is so huge that using regular measurements wouldn't make sense. For instance, Jupiter is about 5.2 AUs from the Sun.
Simplification: Using AUs makes it simpler to compare distances in our solar system. For example, Mars is about 1.5 AUs away from the Sun.
Relative Scale: AUs help astronomers understand distances to other stars and galaxies. This makes studying and exploring space a lot easier.
In short, the AU is a key tool that helps us learn about the universe!
