Glossary term: Capricornus
Description: Capricornus is the smallest constellation in the Zodiac. The stars that make up this constellation are in the part of the sky that intersects with the ecliptic (the plane defined by the Earth's path around the Sun). In fact, all the constellations that comprise the Zodiac intersect the ecliptic. From Earth, we can regularly find the planets, and also the Sun, in the constellation Capricornus. In the case of the Sun this occurs from late January to mid-February (at that time, of course, we cannot see the constellation's stars). Capricornus is one of the 88 modern constellations defined by the International Astronomical Union, but goes back much further – it was already one of the 48 constellations named by the 2nd century astronomer Claudius Ptolemy. The stars that make up the constellation Capricornus are relatively faint. With a telescope, you can find the globular cluster M30 in Capricornus.
