The nearest star to our solar system is Proxima Centauri and if we traveled at the speed of light we would get there after<u> 4.25 years. </u>
<h3>How long would it take to reach Proxima Centauri?</h3>
Proxima Centauri is the nearest star to our solar system and it is located around 40,208,000,000,000 km away.
If we were to travel to it at the speed of light, we would get there in:
= Distance to Proxima Centauri / Light travelling distance per year
= 40,208,000,000,000 / 9,460,730,474,334 km/ year
= 4.25 years
