Betelgeuse, a bright reddish star in the constellation Orion. It is about 495 light-years from the earth, though some measurements put it at about 640 light-years away. Its color indicates a relatively low surface temperature of about 5,000° F. (2,800° C.), about half that of the sun. Betelgeuse is a variable star that fluctuates irregularly in size and brightness. At its smallest, Betelgeuse has a diameter some 300 times that of the sun; its greatest diameter is about one-third larger than this. Betelgeuse is classified in the group of largest known stars, the supergiants.
They exist in the netherworld between solar systems. Sometimes they arise after being ejected from their orbits, endlessly roaming the Milky Way. Could a nomad planet ever wander a little too close?
Pluto is relatively round and orbits the Sun, so why doesn't it qualify as a planet?
