Lupus has no extremely bright starFor alternate meanings see star (disambiguation Hubble Space Telescope of the Sagittarius Star Cloud in the Milky Way Galaxy. A star is any massive gaseous celestial body in outer space. Stars appear as shining points in the nighttime sky that twinkle becs, but has around thirty stars of second and third magnitudeIn science, magnitude refers to the numerical size of something: see orders of magnitude. In mathematics, the magnitude of an object is a non-negative real number, which in simple terms is its length. In astronomy, magnitude refers to the logarithmic meas and 70 of greater than sixth, including a number of binaryA binary star system consists of two stars both orbiting around their barycenter. The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star the union of two stars that are formed together in one sy or multiple stars. The stars which make up the constellation figure have no names, the brightest is α Lupi, a blue giantIn astronomy, a blue giant or blue supergiant is a very hot, very massive (at least 18 times the mass of the sun) blue star of spectral type O or B. In the standard Hertzsprung-Russell diagram, blue giants are found on the upper left corner, thanks to the.
Towards the north of the constellation are globular clusterA globular cluster is a spherical bundle of stars that orbits a galaxy as a satellite. Globular clusters are very tightly gravitationally bound, which gives them their spherical shape, and extremely dense (in relative terms) towards their core. Globular Cs NGC 5824 and NGC 5986 , and close by the dark nebula B 228 . Two open clusters are to the south of the constellation, NGC 5822 and NGC 5749 . On the western border are two spiral galaxies and the Wolf-Rayet planetary nebula IC 4406 , containing some of the hottest stars in existence. Another planetary nebula, NGC 5882 , is towards the centre of the constellation.
