Glossary term: Taurus

Description: Taurus, "the bull", is a constellation in the Zodiac so it's close to the ecliptic – the intersection of the celestial sphere with the plane defined by the orbits of the planets in our Solar System. Hence, from our point of view here on Earth, we can regularly find the planets, and also the Sun, in this constellation – in the case of the Sun from May 14 to June 21. (Of course if the Sun is there, we cannot see the constellation's stars.) Taurus is one of the 88 modern constellations defined by the International Astronomical Union, and also one of the 48 classical constellations named by 2nd century astronomer Claudius Ptolemy. In the northern hemisphere, it's prominently visible in the night sky in winter. Its brightest star is the reddish Aldebaran.
