A group of European astronomers have discovered what they say is the most Earth-like planet to have been found outside our solar system.

Astronomer Michel Mayor: “We have discovered a very low-mass planet. In fact, it is the lowest mass ever discovered. It’s only five times the mass of the Earth. This planet is probably a rocky planet, maybe 50 percent larger than the Earth, very low-mass planet orbiting the star with a period of 13 days.”

The scientists say the planet’s temperatures mean it could support water and possibly life.
