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:
“Through winter-time we call on spring,
And through the spring on summer call,
And when abounding hedges ring
Declare that winter’s best of all;
And after that there’s nothing good
Because the spring-time has not come....”
—William Butler Yeats (1865–1939)
