The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies. Other objects in the catalogue can be found in the other subpages of the list of NGC objects . The constellation information in these tables is taken from The Complete New General Catalogue and Index Catalogue of Nebulae and Star Clusters by J. L. E. Dreyer ...
The total, or bolometric luminosity of the star is 15% higher than the Sun, [7] while the abundance of elements other than hydrogen and helium—what astronomer's term the metallicity—is nearly the same as in the Sun. [8] The stellar atmosphere has an effective temperature of 5,940 [8] K, giving it the yellow-hued glow of a G-type star.

One of the most studied stars is S2, a relatively bright star that also passes close by Sgr A*. As of 2020 [update] , S4714 is the current record holder of closest approach to Sagittarius A*, at about 12.6 astronomical units (1.88 × 10 9 km), almost as close as Saturn gets to the Sun, traveling at about 8% of the speed of light.
This is a visual binary with an orbital period of 5.72 years, an eccentricity of 0.710, and an angular semimajor axis of 69 mas. The primary, component A, is an A-type star showing a mixed spectrum that matches a stellar classification of A3/5 IV/V. [ 3 ] Helmut Abt classified it as an Am star with a spectral type of kA5hF0VmF0. [ 11 ]
The Bayer designation Rho Sagittarii (Rho Sgr, ρ Sagittarii, ρ Sgr) is shared by two stars in the constellation Sagittarius.. ρ 1 Sagittarii [1]; ρ 2 Sagittarii [2]; The two stars are separated by 0.46° in the sky.
