Messier 52 or M52, also known as NGC 7654 or the Scorpion Cluster, is an open cluster of stars in the highly northern constellation of Cassiopeia. It was discovered by Charles Messier in 1774. [ 3 ] [ a ] It can be seen from Earth under a good night sky with binoculars .
Cassiopeia (listen ⓘ) is a constellation and asterism in the northern sky named after the vain queen Cassiopeia, mother of Andromeda, in Greek mythology, who boasted about her unrivaled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy , and it remains one of the 88 modern constellations today.
1 Cassiopeiae is a single [10] star in the northern constellation of Cassiopeia, located around 1,130 light years from the Sun. [1] It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of +4.84. [2]
Rho Cassiopeiae (/ ˌ r oʊ k æ s i ə ˈ p iː aɪ,-s i oʊ-,-iː /; ρ Cas, ρ Cassiopeiae) is a yellow hypergiant star in the constellation Cassiopeia.It is about 8,150 light-years (2,500 pc) from Earth, yet can still be seen by the naked eye as it is over 300,000 times brighter than the Sun.
V762 Cassiopeiae is a red supergiant and a variable star located about 2,500 light-years away in the Cassiopeia constellation. Its apparent magnitude vary between 5.82 and 5.95, which makes it faintly visible to the naked eye under dark skies.
It has 1.39 times the mass of the Sun and is radiating 174 times the Sun's luminosity from its expanded photosphere at an effective temperature of 4,422 K. [5] There is a magnitude 12.50 visual companion at an angular separation of 17.80 arc seconds along a position angle of 61°, as of 2003.
Cassiopeia A (Cas A) (listen ⓘ) is a supernova remnant (SNR) in the constellation Cassiopeia and the brightest extrasolar radio source in the sky at frequencies above 1 GHz. The supernova occurred approximately 11,000 light-years (3.4 kpc ) away within the Milky Way ; [ 2 ] [ 3 ] given the width of the Orion Arm , it lies in the next-nearest ...
The Bayer designation Upsilon Cassiopeiae (υ Cas / υ Cassiopeiae) is shared by two star systems, in the constellation Cassiopeia: υ¹ Cassiopeiae; υ² Cassiopeiae; They are separated by 0.3° on the sky. [1]
