The absolute magnitude M, of a star or astronomical object is defined as the apparent magnitude it would have as seen from a distance of 10 parsecs (33 ly). The absolute magnitude of the Sun is 4.83 in the V band (visual), 4.68 in the Gaia satellite's G band (green) and 5.48 in the B band (blue). [20] [21] [22]
NGC 6166 is a supermassive, type cD galaxy, with several smaller galaxies within its envelope. [3]Suspected to have formed through a number of galaxy collisions, NGC 6166 has a large number of globular clusters (estimated as between 6,200 and 22,000 in 1996) [2] orbiting the galaxy. [4]

Messier 90 is a member of the Virgo Cluster, [5] being one of its largest and brightest spiral galaxies, with an absolute magnitude of around −22 (brighter than the Andromeda Galaxy). [6] The galaxy is found about 1.5° from the central subgroup of Messier 87 . [ 7 ]
HD 154345 is a star in the northern constellation of Hercules.With an apparent visual magnitude of +6.76 [2] it is a challenge to view with the naked eye, but using binoculars it is an easy target. [8]
It was discovered on May 3, 1764, [10] and was the first Messier object to be discovered by Charles Messier himself. Messier originally mistook the object for a nebula without stars. This mistake was corrected after the stars were resolved by William Herschel around 1784. [11] Since then, it has become one of the best-studied globular clusters.
