They are listed in order of decreasing sidereal hour angle, or from the vernal equinoxwestward across the sky. Starting with Ankaa in the constellation Phoenix, the list includes stars from the constellations Eridanus, Carina, Crux, Centaurus, Libra, Triangulum Australe, Scorpio, Sagittarius, Pavo, and Grus.
It contains Ursa Major and the Hyades star cluster, among others. The Local Bubble also contains the neighboring G-Cloud, which contains the stars Alpha Centauri and Altair. In the galactic context, the Local Bubble is a small part of the Orion Arm, which contains most stars that we can see without a telescope.
List of nearest stars by spectral type. Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C . The Alpha Centauri star system is the closest star system to the Sun.
Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares ', i.e ...
The longitude of the ascending node (bright green) as a part of a diagram of orbital parameters. The longitude of the ascending node (symbol ☊) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending ...
The most luminous known star. Quyllur: 2.1878: 5,540 2023 First red supergiant at cosmological distances. Mothra: 2.091: 5,400 2023 A binary consisting of a yellow supergiant and a B-type star. MACS J1149 Lensed Star 1: 1.49: 4,410 2018 The most distant known star prior to the discovery of Earendel. SDSS J1229+1122: 0.000127 17 2013
Hipparchus star catalog. The Hipparchus star catalog is a list of at least 850 stars that also contained coordinates of stellar positions in the sky, based on celestial equatorial latitude and longitude. [1] According to British classcist Thomas Heath, Hipparchus was the first to employ such a method to map the stars, at least in the West. [2]
Astronomical coordinate systems. A star 's galactic, ecliptic, and equatorial coordinates, as projected on the celestial sphere. Ecliptic and equatorial coordinates share the March equinox as the primary direction, and galactic coordinates are referred to the galactic center. The origin of coordinates (the "center of the sphere") is ambiguous ...
