Finding Stars and Constellations: Gemini, including Pollux and Castor

In order to find the constellation of Gemini, we need to draw a line from Rigel to Betelgeuse in the constellation of Orion and continue it for about 1.5 times the distance between those 2 stars. This will takes to the vicinity of Pollux and Castor, the 2 most brilliant starts in the constellation of Gemini.

Pollux (Beta Geminorum) is a star which has 8.8 times the radius of the Sun. It is located 33.7 light years from Earth.

Castor (Alpha Geminorum) is actually a system of 6 stars. It is located 51 light years from Earth.
