Question

The distance from Earth to the star Proxima Centauri is 4.01 × 10^13 kilometers. What is this distance in lightyears? One light year is equal to 9.46 × 10^12 kilometers.A. 0.424 light yearsB. 4.24 light yearsC. 42.4 light yearsD. 424 light years

Answer 1

Given:

The distance from the earth to Proxima Centauri is

`d=\text{ 4.01}*10^(13)\text{ km}`

Also,

`1\text{ light year = 9.46 }*10^(12)\text{ km}`

To find the distance between the earth and Proxima Centauri in light-years.

Step-by-step explanation:

The distance from the Earth to the Proxima Centauri is

`\begin{gathered} d=(4.01*10^(13))/(9.46*10^(12)) \\ =\text{ 4.24 light years} \end{gathered}`

Thus, the correct option is B
