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]
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]

Sky brightness refers to the visual perception of the sky and how it scatters and diffuses light. The fact that the sky is not completely dark at night is easily visible. If light sources (e.g. the Moon and light pollution ) were removed from the night sky , only direct starlight would be visible.
Watch the Moon pass a couple of bright stars and planets, see below for dates. Evening sky: Saturn is getting lower in the southwest and sets around 9 p.m. in early January and around 7 p.m. by ...
The constellation's brightest star is Gamma Microscopii of apparent magnitude 4.68, a yellow giant 2.5 times the Sun's mass located 223 ± 8 light-years distant. It passed within 1.14 and 3.45 light-years of the Sun some 3.9 million years ago, possibly disturbing the outer Solar System.
The European Southern Observatory spotted the object, J0529-4351, during a 1980 sky survey, but it was thought to be a star. It was not identified as a quasar — the extremely active and luminous ...
“Because it's so close to the sun in the sky, the glare of the sun is making it extremely challenging to find it in the sky,” Fazekas said. Still, the comet is there, rounding the sun.
