Orion series - 2
Orion, a constellation often referred to as the Hunter, is a prominent constellation, perhaps the best-known and most conspicuous in the sky. Its brilliant stars are found on the celestial equator and are visible throughout the world, making this constellation universally recognized. In the northern hemisphere Orion is visible in the evening from November to April.
The constellation is extremely rich in bright stars and in deep-sky objects. Here are some of its stars:
* λ Ori (Meissa) is Orion's head.
* α Ori (Betelgeuse), at its right shoulder, is a red star with a diameter possibly larger than the orbit of Mars. Although it is the α-star, it is somewhat fainter than Rigel. Betelgeuse is actually a sextuple star (other studies say it has only two companions, and the existence of any companion at all is disputed), but its companions are too small to be easily seen. It forms a point of the Winter Triangle (source : WP.)
