More details on objects' alternative names can be found at Star Names .

Location of Scorpius X-1

The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Scorpius X-1, the location is 16h 19m 55.07 and -15° 38` 25.02 .

Distance to Scorpius X-1

The Parallax of the star is given as 0.30000 which gives a calculated distance to Scorpius X-1 of 10872.11 light years from the Earth or 3333.33 parsecs. It is about 63,913,061,706,043,258 miles from Earth.

The star is roughly 687,543,875.74 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.

Travel Time to Scorpius X-1

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.
