The distance of the nearest star, Proxima Centauri, from the Earth is 4.0 x 10 13 km. Express it in light year.

1 Light year = 9.46 x 10 12 km or 9.46 x 10 12 km = 1 Light year 4.0 x 10 13 km = x 4.0 x 10 13 = 4.2 light years. Hence, distance of the nearest star from earth = 4.2 light years.

Answer

1 Light year = 9.46 x 10¹² km

or 9.46 x 10¹² km = 1 Light year

∴ 4.0 x 10¹³ km

= $\dfrac{1}{9.46 \times 10^{12}}$ x 4.0 x 10¹³

= 4.2 light years.

Hence, distance of the nearest star from earth = 4.2 light years.
