Planets found beyond solar system

A huge telescope that blasted into space ten months ago has found five new planets outside our solar system.

They're called exoplanets and have been named Keplar 4b, 5b, 6b, 7b and 8b after the telescope that spotted them.

The exoplanets are hotter than molten lava, which scientists say makes them much too hot to support life.

The smallest exoplanet is four times the size of Earth, while the biggest is much larger then Jupiter the biggest planet in the solar system.

Nasa's Kepler Space Telescope blasted off from Cape Canaveral Air Force Station in America on 6 March, 2009.

It has the largest camera ever launched into space and will spend three and and half years checking out more than 100,000 stars to see if they're being orbited by Earth-like planets.

The Kepler telescope is incredibly powerful.

Nasa says that if the telescope was to look at a small town on Earth it would detect the dimming of a porch light as somebody passed in front of it.
