A new study using two NASA solar observatories reveals that asteroid 3200 Phaethons tail is not dusty at all but is actually made of sodium gas. Because it moved so little while the other stars moved much more, it played a special role in the mythology of several Native American tribes, for example (some called it the fastener of the sky). Like before, the SMC, LMC, and the pole will all be points on an equilateral triangle on an imaginary circle. constellation of Draco every 26,000 years (often called "precession of The apparent motion of celestial objects in the sky around the pole is shown by the circular arrow. Gazing up, you get the impression that the sky is a great hollow dome with you at the center (Figure 2.2), and all the stars are an equal distance from you on the surface of the dome. What is the altitude of the north celestial pole for an observer located on the earth's equator?

A grouping of stars such as the Big Dipper has the same shape during the course of the night, although it turns with the sky. Etymology. . E to W in about 12 hours from sunrise to Today, we know that it is not the celestial sphere that turns as night and day proceed, but rather the planet on which we live. analogous to the latitude of the terrestrial north pole. Astronomical twilight . In about 5,500 years, the pole will have moved near the position of the star Alderamin (Alpha Cephei), and in 12,000 years, Vega (Alpha Lyrae) will become the "North Star", though it will be about six degrees from the true north celestial pole.
