It is the middle and brightest of the three stars of Orion's Belt. Alnilam is a B-type blue supergiant; despite being nearly twice as far from the Sun as the other two belt stars, its luminosity makes it nearly equal in magnitude. Alnilam is losing mass quickly, a consequence of its size. It is the farthest major star in Orion at 1,344 light years.

Chi 1 Orionis (χ 1 Ori, χ 1 Orionis) is a star about 28 light years away. [1] It is in the constellation Orion, where it can be seen in the tip of the hunter's upraised club. [11] A light curve for Chi 1 Orionis, plotted from TESS data. [12] The 5.5 day period derived by Stępień and Geyer is marked in red. χ 1 Ori is a G0V star. [7]
The Gould Belt is a local ring of stars in the Milky Way, tilted away from the galactic plane by about 16–20 degrees, first reported by John Herschel and Benjamin Gould in the 19th century. [1] It contains many O- and B-type stars , and many of the nearest star-forming regions of the local Orion Arm , to which the Sun belongs.
Map showing the location of NGC 2169. NGC 2169 is an open cluster in the Orion constellation. It was possibly discovered by Giovanni Batista Hodierna before 1654 and discovered by William Herschel on October 15, 1784. [1] NGC 2169 is at a distance of about 3,600 light years away from Earth.
Of particular note among these stars are "the dog star" Sirius, the brightest star in the sky, and four stars of the easily identified constellation Orion. Equatorial stars of the western hemisphere The equatorial region of the celestial sphere's western hemisphere includes 13 navigational stars from Gienah in the constellation Corvus to Markab ...
Palisa-Wolf-Sternatlas - picture in the star constellation Orion. The Palisa-Wolf-Star Map or Palisa-Wolf-Star Atlas (German: Palisa-Wolf-Sternatlas) is a map series produced between 1900 and 1916 as well as published between 1900 and 1931, which shows the entire starry sky visible in Europe in 210 large-scale sheets.
