Question

Rank the following items that describe distances from longest distance (left) to shortest distance (right).

a. one light-year, the distance across our solar system (to Neptune)
b. astronomical unit (AU)
c. the distance from the Milky Way Galaxy to the Andromeda Galaxy
d. the distance from the Sun to the center of the Milky Way Galaxy
e. the average distance from Earth to the Sun

Answer 1

Answer:

Explanation:

1 AU = 1.58 x 10⁻⁵ light years

the distance from the Milky Way Galaxy to the Andromeda Galaxy = 2.5 million light years

the distance from the Sun to the center of the Milky Way Galaxy = .1 million light years

the average distance from Earth to the Sun = 1 AU .

So longest to shortest distance

the distance from the Milky Way Galaxy to the Andromeda Galaxy  >the distance from the Sun to the center of the Milky Way Galaxy > one light-year, the distance across our solar system (to Neptune) >astronomical unit (AU) = the average distance from Earth to the Sun
