WebUsing distance moduli makes computing magnitudes easy. As for instance, a solar type star (M= 5) in the Andromeda Galaxy (DM= 24.4) would have an apparent magnitude (m) of 5 + 24.4 = 29.4, so it would be barely visible for the HST, which has a limiting magnitude of about 30 [1]. This calculation can be done quickly in one's head. WebApr 10, 2024 · Magnitude measures how bright an object in space is. The brightest object in space is measured at -26.74, and it comes as no surprise that that object is the Sun. The dimmest objects we can see unaided without using a pair of binoculars or a telescope have a magnitude of 6.5. WebAlternatively, if we know the distance and the apparent magnitude of a star, we can calculate its absolute magnitude. Both calculations are made using: with m – M known … clegg chiropractor
