What star has the brightest apparent magnitude as seen from earth?
The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.
Is sun the brightest star?
The brightness of a star is usually referred to as its magnitude. Every star has two magnitudes. The apparent magnitude is how bright it appears to us here on earth. The absolute magnitude is the apparent magnitude that the star would have, if it were viewed from a standard distance. The apparent magnitude of our sun is vastly greater than that of any other celestial object. In terms of absolute magnitude, our sun can't begin to compare with some of the big bright stars in the universe.
What is the magnitude of Pluto?
At its brightest its apparent magnitude is 13.65.
What is the name of the brightness of a star viewed from earth?
Apparent magnitude.
What does apparent magnitude depend upon?
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
What is the apparent magnitude of the star Deneb?
The apparent magnitude of Deneb is +1.25, a fairly bright bright star from Earth.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
What star is the brightest?
The Sun (Sol) has an apparent magnitude of - 26.74Siruis (Dog star) with an apparent magnitude of -1.47 (Brightest in the Northern Hemisphere)Canopus with an apparent magnitude of -0.72 (Brightest in the Southern Hemisphere)Arcturus with an apparent magnitude of -0.04 (Variable)Alpha Centauri A with an apparent magnitude of -0.01Vega with an apparent magnitude of 0.03Rigel with apparent magnitude of 0.18Procyon with apparent magnitude of 0.34Achernar with apparent magnitude of 0.50Betelgeuse with apparent magnitude of 0.58 (Variable)A lower number means more brightness. All of these are apparent magnitudes. If you mean intrinsic magnitude, the answers are somewhat different. Sirius and Alpha Centauri A are bright because they're close to us. Canopus, on the other hand, is much brighter, but also much further away (Sirius is about 8 light years away; Canopus is more than 300 light years away).Off subject:Some planets are brighter (in apparent magnitude) than stars; for example, when Venus appears in the sky, she is always the brightest object (after the Sun and the Moon). In fact, Venus is bright enough to be seen in the broad daylight, if you know where to look. Planets look like stars, but their movement between the stars can be detected if you observe them just for a few nights.
What is an example of apparent magnitude?
Apparent magnitude is a measure of how bright a celestial object appears from Earth. For example, the star Sirius, which is the brightest star in the night sky, has an apparent magnitude of about -1.46. This value indicates its brightness relative to other stars, with lower numbers representing brighter objects.
Compare and contrast apparent magnitude and absolute magnitude?
Apparent magnitude is the brightness of a celestial object as seen from Earth, taking into account distance and extinction from the atmosphere. Absolute magnitude measures the intrinsic brightness of a celestial object if it were placed at a standard distance of 10 parsecs (about 32.6 light-years) away from Earth. In essence, apparent magnitude is how bright an object appears from Earth, while absolute magnitude is how bright it would be at a standardized distance.
What is an apparent magnitude?
Apparent magnitude is a measure of how bright a celestial object appears from Earth. It is a logarithmic scale where lower numbers indicate brighter objects. Apparent magnitude takes into account the intrinsic brightness of the object as well as its distance from Earth.
Would the apparent magnitude of the sun increase or decrease if it were farther away from Earth?
The numeric value of the apparent magnitude would increase, since bright objects have lower magnitude values than dim objects.To give some actual numbers as an example: the Sun has an apparent magnitude of about -27. It is much, much brighter than the moon, which at its brightest has an apparent magnitude of -13 or so.
