Star
A star is a massive, luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on the planet. Other stars are visible from Earth during the night when they are not obscured by atmospheric phenomena, appearing as a multitude of fixed luminous points because of their immense distance. Historically, the most prominent stars on the celestial sphere were grouped together into constellations and asterisms, and the brightest stars gained proper names. Extensive catalogues of stars have been assembled by astronomers, which provide standardized star designations.

Famous quotes containing the word star:
“Events, actions arise, that must be sung, that will sing themselves. Who can doubt, that poetry will revive and lead in a new age, as the star in the constellation Harp, which now flames in our zenith, astronomers announce, shall one day be the pole- star for a thousand years?”
—Ralph Waldo Emerson (1803–1882)
“Never tell me that not one star of all
That slip from heaven at night and softly fall
Has been picked up with stones to build a wall.”
—Robert Frost (1874–1963)
“And though in tinsel chain and popcorn rope
My tree, a captive in your window bay,
Has lost its footing on my mountain slope
And lost the stars of heaven, may, oh, may
The symbol star it lifts against your ceiling
Help me accept its fate with Christmas feeling.”
—Robert Frost (1874–1963)
