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:
“I swear to keep the dead upon my mind,/Disdain for all time to be overglad./Among spring flowers, under summer trees./By chilling autumn waters, in the frosts/Of supercilious winter—all my days/I’ll have as mentors those reproving ghosts.”
—Gwendolyn Brooks (b. 1917)
