Can we reach the nearest star? How far is it from earth?

Answer 1

Yes

The nearest star is the sun. It is about 150 million km's away or a light over 8 light minutes away(the distance light travels in one minute).

The nearest star other than the sun, however, is 4.2 light years away. It is called Proxima Centauri, and we cannot reach it. In order for the fastest objects ever made by man (space probes) to travel that distance we are looking at about 18,000 years to get there.

The nearest star to Earth is Proxima Centauri, which is approximately 4.24 light-years away. Currently, we do not have the technology to travel to Proxima Centauri within a human lifespan.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
