The Sun is the brightest star as viewed from Earth, at −26.78 mag. The second brightest is Sirius at −1.46 mag. For comparison, the brightest non-stellar objects in the Solar System have maximum brightnesses of: the Moon −12.7 mag [1] Venus −4.92 mag; Jupiter −2.94 mag; Mars −2.94 mag; Mercury −2.48 mag; Saturn −0.55 mag [2]
The Sun is by far the brightest object in the Earth's sky, with an apparent magnitude of −26.74. [33] [34] This is about 13 billion times brighter than the next brightest star, Sirius, which has an apparent magnitude of −1.46. [35]

Absolute magnitudes for Solar System objects are frequently quoted based on a distance of 1 AU. These are referred to with a capital H symbol. Since these objects are lit primarily by reflected light from the Sun, an H magnitude is defined as the apparent magnitude of the object at 1 AU from the Sun and 1 AU from the observer. [10]
Some comets have been around for thousands of years, including Comet C/2024 G3, which has already made several passes into the solar system. The last time the comet passed in the solar system was ...
Along the ecliptic plane there are enhancements in the zodiacal light where it is much brighter near the Sun and with a secondary maximum opposite the Sun at 180 degrees longitude (the gegenschein). In extreme cases natural zenith sky brightness can be as high as ~21.0 mag/arcsec², roughly twice as bright as nominal conditions.
This artist's visualisation of WASP-127b, a giant gas planet located about 520 light-years from Earth, shows its newly discovered supersonic jet winds that move around the planet's equator.
