- the sun - How to calculate the apparent magnitude of sun? - Astronomy . . .
The apparent magnitude is how bright it "appears" to be from Earth The only difficulty with finding the apparent magnitude of the sun is that it is so bright that the highly sensitive light detectors that would be used to measure the apparent magnitude of a star would be damaged by the brightness of the sun But that is a practical difficulty
- the sun - Suns apparent magnitude at 2. 5 AU? - Astronomy Stack Exchange
What is the apparent magnitude of the Sun at that distance? Fortunately, there's a formula known as the Distance Modulus which is defined to calculate precisely this information
- A what distance could we see the Sun? - Astronomy Stack Exchange
The Sun has an absolute visual magnitude of about 4 75 This means, that ignoring extinction, it will have an apparent magnitude of 6 at a distance modulus of $6-4 75 = 1 25$
- Does the reflected light from Earth boost Venus apparent magnitude . . .
So, the magnitude of Earth, as seen from Venus in your case should be around -6 8, a lot brighter than the brightest Venus as seen from Earth (magnitude -4 92) How much does this illuminate Venus, compared to the illumination by the sun? When viewed from Earth, the Sun has the impressive apparent magnitude of -26 74
- apparent magnitude - Why was the standard distance set to 10 parsec and . . .
In 1902, the Dutch astronomer Julius Kapteyn defined "absolute magnitude" He wrote: We further define the absolute magnitude (M) of a star, of which the parallax is π and the distance r as the apparent magnitude that star would have if transferred to a distance from the sun corresponding to a parallax of 0 1 [arcseconds]
- Is the Sun visible from Proxima Centauri to human eyes?
The key to this is the so called Absolute Magnitude, which represents the visual magnitude from a distance of 10 parsecs (about 32 light years) The sun is much brighter than Proxima Centauri
- Why is the absolute magnitude of Venus only slightly dimmer than its . . .
Why? The apparent magnitude denotes the planet's visual brightness as seen from Earth (a distance of about 42,000,000 km here), while the absolute magnitude denotes its brightness if it was in a distance of 10 parsecs (32 67 light-years)
- Why is Deneb brighter than Mu Cephei?
The apparent bolometric magnitude of an A-type star, across all wavelengths, is by definition approximately equal to its visual magnitude However, the bolometric magnitude of an M2 giant is roughly 1 5 magnitudes brighter than the visual magnitude I think this accounts for most of any apparent discrepancy
- Compute Planets Apparent Visual Magnitude - Astronomy Stack Exchange
Assume that the second planet is magically lit up entirely by the sun (so it does not have phases when viewed from Earth) Now how can I compute the apparent visual magnitude of the second planet with respect to Earth? If there are other parameters required, please tell me
- Is there a formula for absolute magnitude that does not contain an . . .
Is there a formula for absolute magnitude that does not contain an apparent magnitude term? Ask Question Asked 5 years, 4 months ago Modified 5 years, 4 months ago
