One light-year is the distance light travels in one year. This distance is equal to 9.461 × 10^15 m. After the sun, the star nearest to Earth is Alpha Centauri, which is about 4.35 light-years from Earth. Express this distance in

Answer 1

Answer:

The answer to your question is: 4.12 x 10¹⁶ m

Explanation:

1 light year = 9.461 x 10¹⁵ m

distance Earth to alpha centauri is 4.35 light years

                                    1 light year ----------------- 9.461 x 10¹⁵ m

                                 4.35 light years -------------   x

                               x = 4.35 x 9.461 x 10¹⁵ m / 1 light year

                               x = 4.12 x 10¹⁶ m
