Okay, time for some more information on this new world that NASA astronomers discovered. The new planet has been christened Sedna, after the Inuit goddess of the ocean. It is about three fourths the size of Pluto, and the second reddest object in the solar system. And it is way out there, with a wildly elliptical 10,500 year orbit. Sedna is well beyond the orbit of Pluto and currently approaching perihelion (an object’s closest approach the the sun). In about 72 years Sedna will start it’s long cold journey away from the sun and back towards the Oort Cloud, a region that astronomers theorize contain many of the planetoids that occassionally tumble to the sun and become comets. It boggles the mind to think that the last time this planetoid approached the sun, Earth was locked in an ice age
Here’s the relative sizes of this new planet, Pluto and the Earth.
And check out the orbit of this thing. It is absolutely huge.
