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:
“The flattering, if arbitrary, label, First Lady of the Theatre, takes its toll. The demands are great, not only in energy but eventually in dramatic focus. It is difficult, if not impossible, for a star to occupy an inch of space without bursting seams, cramping everyone elses style and unbalancing a play. No matter how self-effacing a famous player may be, he makes an entrance as a casual neighbor and the audience interest shifts to the house next door.”
—Helen Hayes (19001993)
“I put the gold star up in the front window
beside the flag. Alterations is what I know
and what I did: hems, gussets and seams.”
—Anne Sexton (19281974)
“The star is the ultimate American verification of Jean Jacques Rousseaus Emile. His mere existence proves the perfectability of any man or woman. Oh wonderful pliability of human nature, in a society where anyone can become a celebrity! And where any celebrity ... may become a star!”
—Daniel J. Boorstin (b. 1914)
