Constellation guide to the 88 official constellations which divide up the sky. These constellations are used to help navigate the celestial sphere. The Constellations are patterns in the sky which have been to invented and have deep mythology behind them. Constellations cover massive areas in the sky and as such are very easy to find.

Orion

The Hunter

Orion, a constellation often referred to as The Hunter, is a prominent constellation, perhaps the best-known in the sky. Its brilliant stars, on the celestial equator and visible throughout the world, make this constellation universally recognized.

Constellation Guide Orion

The 'belt and sword' of Orion are frequently referred to in ancient and modern literature, and even found recognition as the shoulder insignia of the 27th Infantry Division of the United States Army during both World Wars, probably because the division's first commander was Major General John F. O'Ryan.

Orion Mythology

Artemis, the goddess of hunt and the moon, fell in love with Orion. She was so entranced by him, she forgot her divinely duty of illuminating the night sky. Her twin brother Apollo, seeing Orion swimming in the sea, dared his sister to strike what only appeared to be a spot on the waves. Not knowing it was Orion, Artemis shot an arrow and killed him. Later, when she found out what she did, she placed his body among the stars. The grief she felt explains why the moon looks so sad at night.

Notable Objects in Orion

Hanging from Orion's belt is his sword, consisting of the multiple stars ?1 and ?2 Orionis, called the Trapezium and the Orion Nebula (M42). This is a spectacular object that can be clearly identified with the naked eye as something other than a star. Using binoculars, its clouds of nascent stars, luminous gas, and dust can be observed.

M78 (NGC 2068) is a nebula in Orion. With an overall magnitude of 8.0, it is significantly dimmer than the Great Orion Nebula that lies to its south.

Another fairly bright nebula in Orion is NGC 1999, also close to the Great Orion Nebula.

Besides these nebulae, surveying Orion with a small telescope will reveal a wealth of interesting deep-sky objects, including M43, M78, as well as multiple stars including Iota Orionis and Sigma Orionis. A larger telescope may reveal objects such as Barnard's Loop and the Flame Nebula (NGC 2024), as well as fainter and tighter multiple stars and nebulae.
