4 Earth-Sized Exoplanets Found Orbiting Nearby Sun-Like Star

UNITED NEWS INTERNATIONAL (UNI) — We might not need to look far in our search for life beyond Earth.

Astronomers say a star that’s a lot like our own sun is likely orbited by four rocky planets and two of them could have liquid surface water.

The star is called Tau Ceti. It’s just 12 light years away in the Cetus constellation.

According to a study due to appear in the Astrophysical Journal, two of Tau Ceti’s exoplanets reside in what experts call the “habitable zone.” They’re far enough away from their star — but not too far — for temperatures to keep water in a liquid state.

And based on our current understanding, water is a key ingredient for life.

There’s just one problem: Tau Ceti is thought to be surrounded by a large disk of debris which would mean its planets are pummeled by asteroids and comets.

Not so good for life. Still, scientists are hopeful.
