A comet is a relatively small astronomical object similar to an asteroid but composed largely of ice. In Earth's solar system, the orbits of comets may extend past that of Pluto; of the comets which enter the is, asteroids, and variable starMost stars are of nearly constant luminosity. Our own Sun is a good example of one which goes through relatively little variation in brightness (usually about 0. 1% over an 11 year solar cycle). Many stars, however, undergo significant variations in lumins. In 1945Events January January 5 The Soviet Union recognizes the new pro-Soviet government of Poland.
