Earth-like planet found

A team of astronomers have found a new planet around five times the mass of Earth, 25,000 light-years away. However any hope of life on it is unlikely as it has a very cold temperature of minus 220 degrees celcius.

The planet was found by using microlensing, which can detect far away planets with the same mass of Earth. It usually takes 1o years to orbit its parent star, a red dwarf which is like the Sun only a lot less hotter.
