List of brightest natural objects in the sky

Edit links
From Wikipedia, the free encyclopedia

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. Objects are listed by their proper names or their most commonly used stellar designation. This list does not include transient objects such as comets, man-made objects, or supernovae.
