Trifid Nebula (M20, NGC6514) Facts Emission/Reflection Nebula in Sagittarius

Trifid Nebula (M20, NGC6514) is an emission/reflection nebula object of interest in space. It lies at a distance of about 5,200.00 light years away in the constellation of Sagittarius.

It is referred to as M(20) when it was catalogued by Charles Messier in 18th - 19th Century France. It is also referred to as NGC(6514) 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 Emission/Reflection Nebula's location is 18:02.6 (R.A.) and -23:02 (Dec.). Its Visual (Apparent) Brightness is 6.00 Magnitude with an apparent dimension of 28.0 . The object can be seen with the naked eye from Earth, that is, you don't need a telescope/binoculars to see it.

Trifid Nebula (M20, NGC6514) has a radius of 21 light years or to put it another way, it has a diameter of 42 light years. It would take a space ship 42 years travelling at the speed of light to get from one side to the other.

Trifid nebula (M20,NGC6514) is a emission/reflection nebula. It was discovered in 1764 by Charles Messier. It's location is RA(18:02.6), Dec(-23:02) and its distance is calculated 5.2 light years away. Its visual Brightness is 9.0. Its apparent dimensions measured in arcmins is 28.0.

Travel Time to Trifid Nebula (M20, NGC6514)

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.
