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:

    One thing about being successful is that I stopped being afraid of dying. Once you’re a star you’re dead already. You’re embalmed.
    Dustin Hoffman (b. 1937)

    The eager fate which carried thee
    Took the largest part of me:
    For this losing is true dying;
    This is lordly man’s down-lying,
    This his slow but sure reclining,
    Star by star his world resigning.
    Ralph Waldo Emerson (1803–1882)

    Relying on any one disciplinary approach—time-out, negotiation, tough love, the star system—puts the parenting team at risk. Why? Because children adapt to any method very quickly; today’s effective technique becomes tomorrow’s worn dance.
    Ron Taffel (20th century)
