Glossary term: Capricorn
Description: Capricorn 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 orbits of the Solar System's planets). Hence, from Earth, we can regularly find the planets, and also the Sun, in the constellation Capricorn. 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). Capricorn 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. Capricorn's stars are relatively faint. With a telescope, you can find the globular cluster M30 in Capricorn.Related Terms:
