Interstellar travel is one of the most debated and exciting topics in science.  Could the closest star to us actually be the first star we ever visit? (or planet near it actually)

At 4.37 light years away, it’s part of the closest star system to our sun. Alpha Centauri is actually two stars, A and B, one slightly larger and more luminous than our own sun, the other slightly smaller.

The two stars orbit one other, swinging in as close as Saturn is to our Sun… then back out to the distance of Pluto. This means that any outer planets in this system… anything beyond, say, the orbit of Mars… would likely have been pulled away by the companion and flung out into space.

For this reason, Alpha Centauri was not high on planet hunters’ lists… until they began studying a star 45 light years away called “Gamma Cephei.” It has a small companion star that goes around it every 76 years. Now, it seems… it also has at least one planet.

Let’s find out how this could be possible or not in the video on the next page
