Answer:
4,390'538,259'694,256 kilometers
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:
[tex]4,570(light year) * \frac{9'460,730'472,580.8 (kilometers)}{1(light year)} = 4,390'538,259'694,256(kilometers)[/tex]
