Earth-size planet found outside solar system
The hunt for planets like our own has come up with a striking discovery.
There's a planet about the same size as Earth and it's right outside of our solar system.
In an image of an artist's impression of the planet, it orbits a star called Alpha Centauri B.
It's the closest planet found beyond our solar system despite being a whopping four light years away. That's about 23.5 trillion miles.
Scientists said it's unlikely that there's another life form on that planet.
