New planet discovered
A name for the planet has yet to be decided on. The planet was found by scientists from the California Institute of Technology using the Samuel Oschin Telescope at Palomar Observatory. It had previously been photographed in 2003, but its movement was only discovered this January, from which time it has been better studied. Experts estimate that it must have a diameter of less than 3200km, but is thought to be wider than Pluto's 2300km.
