Glossary term: Virgo
Description: Virgo is one of the constellations in the Zodiac, i.e. 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 Virgo. In the case of the Sun this occurs from late September to late October (at that time, of course, we cannot see the constellation's stars). Virgo 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. Virgo is notable as the location of the Virgo Cluster, a cluster of over a thousand galaxies which forms the core of a supercluster of which our Galaxy is a memberRelated Terms:
