At what distance would a supernova of absolute magnitude -20 look as bright as the sun?
Sun apparent mag -26.37. The super need to be closer than 10 parsecs. 6.37/2 Mags. ( light dims by a square law. 5 mags= 100 . 1 Mag 2.5118, 3.19...uh 18.9 closer. 1.7LY?
What distance is absolute magnitude based on?
10 parsecs . . . 32.6 light-years
How bright is a star which is actually at a distance of 32.6 light years away from earth called?

What is the greatest distance at which an RR Lyrae star of absolute magnitude 0 could be seen by a telescope capable of detecting objects as faint as 20th magnitude?
Hmm... Absolute Mag is measured at 10 parsecs. 5 mags are 100. 20 is 10^8. distance is a square law. So... 10^4 times 10 parsecs, 32,600 Light yesrs. OK?
What could you say about a star whose absolute visual magnitude was 0 and whose visual magnitude was also 0?
That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.That means that by definition, the star is at the standard distance of 10 parsecs.
What is closer to the number 10 9.99 or 9.9?
9.99 is closer to 10 than 9.9 is.

Order of Magnitude for the number of tires on a motorcycle is 1?
Basically, that means that the number of tires (2) is closer to 1 than to 10.Basically, that means that the number of tires (2) is closer to 1 than to 10.Basically, that means that the number of tires (2) is closer to 1 than to 10.Basically, that means that the number of tires (2) is closer to 1 than to 10.
What is answer -20 closer to -40 or 10?
|-20 - (-40)| = 20 |-20 - 10| = 30 -20 is closer to -40 than 10.
How to convert kilometers per second into parsecs per year?
Your 1 kilometer equals 3.24077649 x 10-14 parsecs. And your second equals 3.16887646 x 10-8 years. Converting kilometers/second to parsecs/year involves multiplying by 3.24077649 x 10-14 and dividing by 3.16887646 x 10-8 to get your answer. Or do that bit of math in advance and then just multiply by 1.022689439 x 10-6 to get your answer. Make sure you have your beginning figure in km per one second. Your answer will appear in parsecs per one year, or just parsecs per year.
What is 6 rounded to the nearest ten?
10
What distance is 300mm?
300mm is 9.72 x 10-18 parsecs.
Which number is larger -5 or -10?
-5 is larger than -10 because the closer a number is to zero, the larger it is. In this case, -5 is closer to zero than -10.
Is square root of 10 closer to 3 or 4?
The square root of 10 is 3.1622776601683793319988935444327, so it is closer to 3 than 4
Is -10 larger than -20?
10
What distance is absolute magnitude based on?
10 parsecs . . . 32.6 light-years
If two stars have the same apparent magnitude are they the same distance from Earth?
No. Brighter distant stars can have the same apparent magnitude as fainter stars that are closer.(Absolute magnitude does not refer to actual brightness, but rather to what the brightness of a star would likely be at an arbitrary distance of 10 parsecs, rather than its actual distance.)
