Explain why the units we use on earth to measure distance are not practical to use for measuring distance in space.
Answers: 2
. For farther objects, it is even unpractical to measure the distance in million km. For example, the closest star to the Sun, Proxima Centauri, is 4.2 light-years from us (the light-year is the distance covered by the light in one year: 1 light year is equivalent to 
).
