At 9 p.m. they are seen high in the south southwest. Saturn is seen to the lower right of the brighter Jupiter. Both are below the Pleiades or Seven Sisters star cluster. Both planets appear in the constellation of Taurus the bull, and are wonderful sights in small telescopes as is Venus. Tomorrow morning Mars will be seen below and right of the moon.
Astronomers call small stars dwarfs.
Red dwarfs have much less mass than the sun, so never get very bright and stay a cool red for most of their long lives. White dwarfs are different. They used to be sun massed stars, that ran out of fuel to keep them shining , and to keep up their size. They then shrunk to their current size. A star like the sun, over 300 thousand times the mass of the earth, and 100 times its diameter would shrink to a sphere just twice the size of the earth.
