Basic Observations of Stars
... The apparent distribution of stars as seen on the sky can be monitored and the ‘sideways’ motions measured as changing directions, expressed as angles. This is called the star’s proper motion. (To calculate the actual speeds through space, we need to know their distances as well.) The changes are mo ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
