Monoceros is a faint constellation on the celestial equator. Its name is Greek for unicorn. Monoceros is a relatively modern constellation. Its first certain appearance was on a globe created by the Dutch cartographer Petrus Plancius in 1612 or 1613 and it was later charted by Jakob Bartsch as Unicornus in his star chart of 1624. It is bordered by Orion to the west, Gemini to the north, Canis Major to the south and Hydra to the east. Other bordering constellations include Canis Minor, Lepus and Puppis. Canis Major and Canis Minor are two of the 48 constellations listed by the 2nd century astronomer Ptolemy, and they remain two of the 88 modern constellations defined by the International Astronomical Union. Canis Major is Latin for, greater dog, Canis Minor is Latin for, lesser dog, they are commonly represented as the dogs following Orion the hunter.
