The new planetoid has been named Sedna after the Inuit goddess of the ocean, and is eight billion miles away in the furthest reaches of the solar system, three times the distance from Earth than the previously furthest known planet, Pluto.
A NASA funded team today announced the discovery of a planetoid located a mere 8 billion miles from Earth.
The discovery of a small planetoid in the Kuiper belt, the distant disk of debris whose chunks eventually formed the solar system, make Pluto's chances of holding onto its status of bona fide planet weaker.
Sedna, the planetoid 1,000 miles in diameter discovered several weeks ago, was first photographed with a small moon orbiting its icy sphere.
It orbits the sun on a highly elliptical path which, even at its perihelion, puts the planetoid more than twice the average distance from the Sun to Pluto.
The Earth and Moon formed rather late in this process, from a collision between two large bodies - a mars-sized planetoid and a slightly larger body.
I've heard a good astronomical theory that the moon was created by a planetoid crashing into the earth a long time ago, possibly carrying with it the seeds for life itself.
He and his colleagues expected that the images would show two distinct objects - the planetoid and its moon.
The planetoid , believed to be half rock and half ice, is named after the Inuit goddess said to have created the sea creatures of the Arctic.
Another highly notable location is the galaxy's largest spaceship dump, which may be found around the back side of the planetoid .
