kilometers?

Answer 1

Distance in kilometre = 4.242 x 10¹² km

Step-by-step explanation:

Given:

Distance of Proxima Centauri = 4.242 light years

Find:

Distance in kilometre

Computation:

1 light year = 10,000,000,000,000 km

So,

4.242 light years = 4.242 x 10,000,000,000,000

Distance in kilometre = 4.242 x 10¹² km
