SCIENTISTS have found a new world orbiting the solar system - more than 3 billion kilometres further away from the Sun than Pluto.

It is provisionally known as Sedna, after the Inuit goddess of the sea.
The discovery of Sedna - 10 billion kilometres from Earth - is a testament to the new generation of high-powered telescopes.
Measurements suggest Sedna's diameter is almost 2000km - the biggest find in the solar system since Pluto was discovered 74 years ago. It is believed to be made of ice and rock, and is slightly smaller than Pluto.
The find will reignite the debate over what constitutes a planet. Some scientists claim even Pluto is too small to count as one.
According to astronomer Michael Brown of the California Institute of Technology, who discovered Sedna, there could be many other new worlds orbiting the Sun and waiting to be discovered.
