Messier 55 (NGC6809) is a globular cluster object of interest in space. It lies at a distance of about 17,600.00 light years away in the constellation of Sagittarius.

It is referred to as M(55) when it was catalogued by Charles Messier in 18th - 19th Century France. It is also referred to as NGC(6809) in the New General Catalogue. This is a list of deep space objects that was compiled by John Louis Emil Dreyer in 1888 in an update to John Herschel earlier catalogue.

The Globular Cluster's location is 19:40 (R.A.) and -30:58 (Dec.). Its Visual (Apparent) Brightness is 7.00 Magnitude with an apparent dimension of 19.0 . The object can not be seen by the naked eye from Earth, you need a telescope to see it.

(M55,NGC6809) is a globular cluster. It was discovered in 1751 by Abbe Nicholas Louis de la Caille. It's location is RA(19:40), Dec(-30:58) and its distance is calculated 17.6 light years away. Its visual Brightness is 6.3. Its apparent dimensions measured in arcmins is 19.0.

Travel Time to Messier 55 (NGC6809)

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
