Messier 69 (also known as M69 or NGC 6637) is a globular cluster in the constellation Sagittarius. The solar mass is a standard way to express Mass in Astronomy, used to describe the masses of other Stars and galaxies. The New General Catalogue ( NGC) is the best-known catalogue of Deep sky objects in Amateur astronomy. A globular cluster is a spherical collection of Stars that orbits a galactic core as a Satellite. This is a list of Globular clusters. The apparentmagnitude does not include an extinction correction A globular cluster is a spherical collection of Stars that orbits a galactic core as a Satellite. In common usage a constellation is a group of celestial bodies that are connected together in some arrangement typically stars to form a visible figure or picture It was discovered by Charles Messier in August 31, 1780, the same night he discovered M70. Charles Messier ( June 26, 1730 &ndash April 12, 1817) was a French astronomer most notable for publishing an Year 1780 ( MDCCLXXX) was a Leap year starting on Saturday (link will display the full calendar of the Gregorian calendar (or a At the time, he was searching for an object described by LaCaille in 1751-2 and thought he had rediscovered it, but it is unclear if LaCaille actually described M69.
M69 is at a distance of about 29,700 light-years away from Earth and has a spatial radius of 42 light-years. A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 It is a close neighbor of Globular Cluster M70, 1,800 light-years separating the two objects, and both these clusters lie close to the Galactic Center. Messier 70 (also known as M70 or NGC 6681) is a Globular cluster in the Constellation Sagittarius. The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Γαλαξίας (Galaxias sometimes referred to simply It is one of the most metal-rich globular cluster known.
