V391 Pegasi b is a star that is 4,570 light years away from Earth. What is this distance in kilometers?

Answer 1

4,390'538,259'694,256 kilometers

Step-by-step explanation:

Light years is a distance measure that represents the distance the light travels in the vacuum in a year and it is approximately equal to 9'460,730'472,580.8 kilometers. Then, if V391 Pegasi is 4,570 light years away from earth:

`4,570(light year) * (9'460,730'472,580.8 (kilometers))/(1(light year))  = 4,390'538,259'694,256(kilometers)`

Answer 2

Its 43232 kilometers away
