Sedna

Sedna is a large minor planet in the outer reaches of the Solar System that was, as of 2015, at a distance of about 86 AU from the Sun, about three times as far as Neptune. Spectroscopy has revealed that Sedna's surface composition is similar to that of some other trans-Neptunian objects, being largely a mixture of water, methane and nitrogen ices with tholins. Its surface is one of the reddest among Solar System objects. It is most likely a dwarf planet. Sedna is Also Home of The Sednians.
