Question

The distance from the sun to Earth would be _______.

a. less than one light year
b. more than one light year
c. exactly one light year
d. any number of light years

Answer 1

distance between sun and earth is 1 AU

`1 AU = 1.49 * 10^(11) meter`

now 1 light year is defined as distance covered by light in one year

so we will have

`1 Ly = 3 * 10^8 * (365*24*3600s)`

`1 Ly = 9.46 * 10^15 meter`

So 1 Ly is more than the distance between sun and earth
