Johnson, L. (2013). The Closest Extra-solar Planet to Earth. Retrieved from

Description: Les Johnson talks about the new discovery of a possible earth-like planet that scientists have found in the Alpha Centauri star system.

Summary: Alpha Centauri is not a single star. It is a binary star which means that it's two start located very close together. This star has been named Centauri AB and there is also a third star named Centauri C which is connected in orbit with Centauri AB. There have now been over 800 new planets discovered outside of our solar system. They have discovered a planet orbiting Alpha Centauri and are trying to be able to study and discover more about it.

Excerpt: Alpha Centauri A and B are particularly interesting for astronomers and science fiction writers because they are both very similar to our sun. If Sol, our sun, is “just right” for producing planets with life, then it would make sense that other similar stars could do the same. And since they are close, at least in astronomical distances – I wouldn’t call being ~25,278 billion miles away “close,” – any planets found there would be exciting and hugely significant. After all, if we ever achieve the ability to travel between the stars, Alpha Centauri AB-C would be our likely first destination and wouldn’t it be great if we found life there?
