The Spring Triangle is an astronomical asterism involving an imaginary triangle drawn upon the celestial sphere, with its defining vertices at Arcturus, Spica, and alternately Denebola or Regulus. This triangle connects the constellations of Boötes, Virgo, and Leo. It is visible in the northern hemisphere night sky between March and May.
It forms part of a larger Spring asterism called the Great Diamond.
Famous quotes containing the word spring:
“Whatever does not spring from a man’s free choice, or is only the result of instruction and guidance, does not enter into his very being, but still remains alien to his true nature; he does not perform it with truly human energies, but merely with mechanical exactness.”
—Karl Wilhelm Von Humboldt (1767–1835)
