Astronomers use magnitudes to describe the brightness of an object in the sky. It is a non-linear, numerical scale where the smaller numbers represent brighter objects. Generally, the unaided eye can see stars down to magnitude 6 in good skies. Pluto is magnitude 14, and thus, is invisible without optical aid or photography. Venus has a magnitude of about -4 and the Sun is -27.

| magnitude |
The degree of brightness of a celestial body as seen from the Earth designated on a numerical scale, on which the brightest star has magnitude ?.4 and the faintest visible star has magnitude 6, with the scale rule such that a decrease of one unit represents an increase in apparent brightness by a factor of 2.512. Negative magnitudes are reserved for the most brilliant objects: the Full Moon is ?2.7; the Sun is ?6.7.
