• astronomical unit

• eclipse

• light year

• rotation

the distance that light can travel in a year

• astronomical unit

• light year

• bright year

Why do we use light years and astronomical units to measure distances in space?

• 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.

Because distances in space are so great that conventional numbers are too large to work with, astronomers use a unit of measurement called

• dark years

• leap years

• light years

• hight years
