The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north. It uses the right-handed convention ...
The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center A starchart of the night sky towards the Galactic Center The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1][2] Its central massive object is a supermassive ...
Sagittarius A*, abbreviated as Sgr A* (/ ˈsædʒˈeɪstɑːr / SADGE-AY-star[ 3 ]), is the supermassive black hole [ 4 ][ 5 ][ 6 ] at the Galactic Center of the Milky Way. Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [ 7 ] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.

The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), [ 10 ] but only about 1,000 light-years thick at the spiral arms (more at the bulge).
There exist 5-point, 4-point and 3-point degenerate cases of Pascal's theorem. In a degenerate case, two previously connected points of the figure will formally coincide and the connecting line becomes the tangent at the coalesced point.
A globular cluster is a spheroidal conglomeration of stars that is bound together by gravity, with a higher concentration of stars towards its center. It can contain anywhere from tens of thousands to many millions of member stars, [2] all orbiting in a stable, compact formation. Globular clusters are similar in form to dwarf spheroidal ...
Satellite galaxies that orbit from 1,000 ly (310 pc) of the edge of the disc of the Milky Way Galaxy to the edge of the dark matter halo of the Milky Way at 980,000 ly (300 kpc) from the center of the galaxy, [ a ] are generally depleted in hydrogen gas compared to those that orbit more distantly. This is because of their interactions with the ...
