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:

    Find out the peaceful hermitage,
    The hairy gown and mossy cell,
    Where I may sit and rightly spell
    Of every star that heaven doth show,
    And every herb that sips the dew;
    Till old experience do attain
    To something like prophetic strain.
    These pleasures Melancholy give,
    And I with thee will choose to live.
    John Milton (1608–1674)

    Firmness yclept in heroes, kings and seamen,
    That is, when they succeed; but greatly blamed
    As obstinacy, both in men and women,
    Whene’er their triumph pales, or star is tamed —
    And ‘twill perplex the casuist in morality
    To fix the due bounds of this dangerous quality.
    George Gordon Noel Byron (1788–1824)

    With an occasional dream, a vision ...
