What is the apparent magnitude of the star polaris?
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
What is the color size and apparent brightness of polaris?
The main star in the Polaris system, Polaris Aa, is a yellow super-giant, with a radius which is 46 +/- 3 times that of the sun. Its apparent magnitude is 1.98 but it is a Cepheid variable.
Does Polaris reflect light?
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
What is the Antares absolute magnitude and its apparent magnitude?
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
What is the color size and apparent brightness of Vega Polaris and Arcturus?
Arcturus is orange in color, and has a mass of 2.188E30 kg. Vega has an apparent magnitude of 0.03, a white color, and the size is unknown. Comments. That answer does not fully answer the question. For example there's nothing about Polaris.
How bright is a Polaris star?
The main star of the system is Ursa Minor Aa which is a Cepheid Variable. Its apparent magnitude averages at 1.98
How many times is the star polaris brighter than the sun?
Polaris, also known as the North Star, is approximately 2,500 times brighter than the Sun. This brightness is measured in terms of absolute magnitude, where Polaris has an absolute magnitude of about -3.6, compared to the Sun's absolute magnitude of about +4.8. However, the apparent brightness of stars can vary based on their distance from Earth.
What is the apparent magnitude of Neptune?
The apparent magnitude of Neptune is 7.8
What is apparent magnitude of vega?
Vega has an apparent magnitude of 0.03.
The light from Sirius is 24.2 times more intense than light from Polaris What is the magnitude difference?
Apparent magnitude of Sirius = -1.44Apparent magnitude of Polaris = 1.97To the Earthbound observer, Sirius appears (1.44 + 1.97) = 3.41 magnitudesbrighter than Polaris.1 magnitude = (100)1/6 times as bright3.41 magnitudes = (100)3.41/6 = 13.7 times as bright as Polaris
What is the difference between apparent magnitude and surface magnitude?
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.
What is the apparent magnitude of cartwheel galaxy?
The apparent magnitude of the Cartwheel Galaxy is 15.2
