Although it does not emit its own light like a star, the planet Venus is very close to Earth compared to the stars. This means that the light reflected off its surface from the sun makes it brighter than the distant stars.
Sirius, which means that Rigel is brighter.
The apparent magnitude is 2.4
The apparent magnitude is 4.5821
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
Yes, Rigel has a greater magnitude than Sirius. Rigel has an apparent magnitude of around 0.12, making it one of the brightest stars in the night sky, while Sirius has an apparent magnitude of about -1.46, making it the brightest star in the night sky.
No. Absolute magnitude is an intrinsic property of the star, but apparent magnitude also depends on the star's distance from Earth.
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
Sirius, which means that Rigel is brighter.
The apparent magnitude is 2.4
The apparent magnitude of a star is a measure of its brightness.
That object is easily visible with a pair of binoculars. A star's apparent brightness is exactly 100 times less than another star if its apparent magnitude is +5 greater. So, the star of magnitude 7.3 appears 100 times fainter than a star of magnitude 2.3. (Polaris is a bit brighter than magnitude 2.3).
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).

The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.
Rigel is the brightest star in Orion and the sixth brightest star in the sky, with an apparent magnitude of 0.18.
