Question

1 star is 3.4 light years away from the Earth what does it mean

Answer 1

Explanation:

Light year is a unit of measurement of distance involving huge distances. Light year can be defined as the distance travelled by light in one year, in space. It is equal to 9.461 × 10^12 kilometres. If one star is 3.4 light years away from the earth, then distance between star and earth is 3.4* 9.461 ×10^12

Answer 2

1 light year = 9.146×10¹² Km

it means that the star is 2.8380000000000000 km away from earth .

or you can say

the star is 2.838×10¹³ km away from earth
