Compare the `redness` of Aldebaran, Betelgeuse and Mars this evening in the SouthWest.
Aldebaran – A red giant star which varies irregularly in brightness between magnitudes 0.75 and 0.95 in the constellation of Taurus (The Bull) – see Derekscope Guide :- Wednesday 17th February 2010.
Betelgeuse – A red supergiant star of variable brightness, ranging from about magnitude 0 to 1.3 every 6 years or so, the star actually lies on the Hunter’s shoulder in the constellation of Orion (The Hunter). More information about Betelgeuse.
Mars – This planet is often called The Red Planet because it is covered by red deserts, so it’s a small, rocky planet that in some ways is similar to Earth. It has a 24-hour day, a pattern of seasons that resembles our own, and polar ice-caps. See Derekscope Guide:- Thursday 28th January 2010.
