Which of the following choices orders the components of the universe correctly from largest to smallest?

• planet, star, solar system, galaxy, universe

• galaxy, universe, solar system, star planet

• universe, galaxy, solar system, planet, star

• universe, galaxy, solar system, star, planet

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

the distance that light can travel in a year

• astronomical unit

• light year

• bright year

Distances between galaxies are so large they are measured in a unit that is 9.46 trillion kilometers.

• astronomical unit

• eclipse

• light year

• rotation

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.
