2003 EL61, as it has been cur­rently clas­si­fied, has been dis­cov­ered, and it may be another one of those elu­sive plan­ets that seem to creep up every once in a great while in our solar system.

A new found object in our solar system’s out­skirts may be larger than any known world after Pluto, sci­en­tists said today.

It also has a moon.

Des­ig­nated as 2003 EL61, the main object in the two-body sys­tem is 32 per­cent as mas­sive as Pluto and is esti­mated to be about 70 per­cent of Pluto’s diameter.

Other news reports that the object could be twice as big as Pluto are false, accord­ing to two astronomers who found the object in sep­a­rate stud­ies and another expert who has ana­lyzed the data.

If the mass is only one-third that of Pluto, then the­ory holds that it can’t be larger than Pluto, accord­ing to Brian Mars­den of the Minor Planet Cen­ter, which serves as a clear­ing­house for data on all new­found objects in the solar system.

Mars­den, who was not involved in the dis­cov­ery but has reviewed the data, told SPACE.com that the mass esti­mate is very firm, within 1 or 2 per­cent. “I don’t think it is big­ger than Pluto,” he said.
