Hey neighbors! Nearest sun-like star hosts 4 Earth-sized planets

Last year we learned the nearest star beyond our sun has a planet about the size of Earth, but it's very different than our solar system and not an ideal candidate for finding alien life.

So what about the closest star that would actually remind us of our own beloved sun? We now know that it probably hosts a handful of Earth-like planets, including a pair that might be able to support life.

Tau Ceti is the center of the nearest solar system that's similar to ours, an assumption made stronger by the discovery of four rocky super-Earths orbiting the star just 12 light years away.

Two of the four planets are in the habitable zone around the star where temperatures could be just right for liquid water, and perhaps alien life, to be present.
