Hey space explorers! Why do we use light years and astronomical units (149.6 million kilometers) to measure distances in the vast universe? Join Mason, Aria, and Noah on this cosmic quest!

• Scientists want to sound smart.

• Hubble discovered these units and wanted to use them.

• Space is too small to use km, it wouldn't make sense.

• Space is too big, vast, enormous to use traditional units, like miles.
