Finding Stars and Constellations: Orion
Orion is a constellation relatively easy to find due to the brightness of its stars and the "belt" feature. In the Northern Hemisphere, in January, it is almost always above the horizon. The reason for this is because the"belt" is located in the Celestial Equator of the Celestial Sphere.
The stars to find in Orion are:
Betelgeuse
Bellatrix
Rigel
Saiph
Alnitak (belt)
Alnilam (belt)
Mintaka (belt)
Orion is very useful because it serves as a reference point to locate stars and constellations
