Planet hunters say the system has many similarities to our own
Astronomers in the US say they have found a new planet in orbit around a star 41 light years from Earth.

The discovery brings to five the number of planets orbiting the star, 55 Cancri, the most found to date in a single solar system outside our own.

Astronomers have found more than 250 planets outside our own solar system - the team behind the latest discovery have found more than anyone else.

The new planet is a gas planet about 45 times the mass of the Earth.

Their latest find is a fifth planet to add to the four they had already discovered around 55 Cancri, a double or binary star in the constellation of Cancer.
