Monoceros (The Unicorn)
A faint constellation, but one rich in stars and nebulae by virtue of its location in the Milky Way, straddling the celestial equator next to Orion. It is not one of the ancient constellations but seems to have gained general acceptance in the mid-seventeenth century. Its brightest stars are two of the third magnitude; it contains the Rosette Nebula, the Cone Nebula and Hubble's Variable Nebula.
