(Newser) – Astronomers have found a planet that’s at least 45 times the size of Earth orbiting a star 41 light years away, Space.com reports. The giant ball of gas is the fifth planet discovered around the star 55 Cancri. And while it's not a "twin of our solar system," it is the first outside our own to have five known planets.

A team of astronomers has spent nearly 20 years researching the star and its planets.
The newly discovered planet is the fourth furthest from the star and about half the size of Saturn. “This work marks an exciting next step in the search for worlds like our own,” an astronomer at the National Science Foundation said.
