Answer:
Proxima Centauri is 2.478 x 10¹³ miles from Sun.
Explanation:
Distance of Proxima Centauri to sun = 4.24 light years
1 light year = 5.9 x 10¹² miles.
Distance of Proxima Centauri to sun in miles = Distance in light years x 5.9 x 10¹² miles
So, Distance of Proxima Centauri to sun in miles = 4.2 x 5.9 x 10¹² miles
= 2.478 x 10¹³ miles
So Proxima Centauri is 2.478 x 10¹³ miles from Sun.
