At first magnitude, the red giant Aldebaran is the brightest star in the constellation. In the northeast part of Taurus is Messier 1, more commonly known as the Crab Nebula, a supernova remnant containing a pulsar. One of the closest regions of active star formation, the Taurus-Auriga complex, crosses into the northern part of the constellation.
Ptolemy catalogued 19 stars jointly in this constellation and in the now obsolete constellation of Antinous, which was named in the reign of the emperor Hadrian (AD 117–138), but sometimes erroneously attributed to Tycho Brahe, who catalogued 12 stars in Aquila and seven in Antinous. Hevelius determined 23 stars in the first [4] and 19 in the ...
Eta Aquilae (η Aql, η Aquilae) is a multiple star in the equatorial constellation of Aquila, the eagle.It was once part of the former constellation Antinous.Its apparent visual magnitude varies between 3.49 and 4.3, [3] making it one of the brighter members of Aquila.
The companion, Zeta Tauri B, has about 94% the mass of the Sun, although it is unknown whether this is a main-sequence star, a neutron star, or a white dwarf. If it is a main sequence star, then the mass indicates it may have a stellar classification of G4. [4] The spectrum of the primary component has a stellar classification of B2 IIIpe. [4]
Tau Tauri, Latinized from τ Tauri, is a quadruple star system [5] in the constellation Taurus. It is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.33. [14] The distance to this system is approximately about 400 light years based on parallax. [1]

The absolute magnitude of Beta Tauri is −1.34, similar to another star in Taurus, Maia in the Pleiades star cluster. Like Maia, β Tauri is a B-class giant with a luminosity 700 times solar (L ☉). [18] It has evolved to become a giant star, larger and cooler than when it was on the main sequence. [19]
