Gamma Canis Majoris
Gamma Canis Majoris (γ CMa, γ Canis Majoris) is a star in the constellation Canis Major. It has the traditional name Muliphein,〔(Star Name - R.H.Allen p.130 )〕 not to be confused with ''Muhlifain'', which is Gamma Centauri; both names derive from the same Arabic root, محلفين ''muħlifayn''.
It is unclear exactly why this relatively faint star was given the "gamma" designation, but it is possibly because it is in the same part of the constellation as Sirius (alpha) and Murzim (beta).
γ Canis Majoris is a blue-white B-type bright giant with an apparent magnitude of +4.11. It is approximately 402 light years from Earth. This star has 5.6 times the radius of the Sun and the outer atmosphere has an effective temperature of 13,596 K.〔
==Modern legacy==
Muliphein appears on the flag of Brazil, symbolizing the state of Rondônia.〔(【引用サイトリンク】url=http://www.fotw.net/flags/br_astro.html )〕
