1) Rigel is the brightest star in the Orion constellation. Betelgeuse is the second brightest star in Orion with a variable brightness. Occasionally, Betelgeuse will outshine Rigel when it is at its brightest.
2) Proxima Centauri
4) Milky way band (answers like milky way galaxy, milky way arm also can be considered right).
5) Messier objects.
7) Apparent magnitude.
8) Andromeda galaxy.
9) Cassiopeia. (It is named after a very beautiful queen with a similar name as per the Greek mythology)
10) Orion (Too many questions on Orion! This is the most easily identifiable constellation for many amateur astronomers and would remain an important navigation tool in night sky).
Nearly all the stars that we see in the night sky belong to Milky way galaxy. We get to see Andromeda galaxy as a faint smudge in dark sky conditions in northern hemisphere. But we do not get to see the individual stars of Andromeda galaxy either through direct viewing or using binoculars. This section is just to test and enrich our knowledge about the stars in our own galaxy. Best of luck as you take the plunge.
