This is a list of the brightest natural objects in the sky. This list orders objects by apparent magnitude from Earth , not anywhere else . This list is with reference to naked eye viewing; all objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly.
The Messier catalogue comprises nearly all of the most spectacular examples of the five types of deep-sky object – diffuse nebulae, planetary nebulae, open clusters, globular clusters, and galaxies – visible from European latitudes. Furthermore, almost all of the Messier objects are among the closest to Earth in their respective classes ...

A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep-sky objects (galaxies, nebulae, and star clusters).

If this object were 10 parsecs away from Earth it would appear nearly as bright in the sky as the Sun (apparent magnitude −26.744). This quasar's luminosity is, therefore, about 2 trillion (10 12) times that of the Sun, or about 100 times that of the total light of average large galaxies like our Milky Way. (Note that quasars often vary ...
The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon. Natural light sources in a night sky include moonlight , starlight , and airglow , depending on location and timing.
Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1] although two objects (NGC 4244 and the Hyades) are listed out of sequence.
