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:
“all ignorance toboggans into know
and trudges up to ignorance again:
but winter’s not forever, even snow
melts; and if spring should spoil the game, what then?
all history’s a winter sport or three:”
—E.E. (Edward Estlin)
