Scorpius X-1 has alternative name(s) :- V818 Scorpii.
More details on objects' alternative names can be found at Star Names .
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 .
Scorpius X-1 has a spectral type of Oev E. This means the star is a blue star.
The Parallax of the star is given as 0.30 which gives a calculated distance to Scorpius X-1 of 10872.11 light years from the Earth or 3333.33 parsecs. It would take a spaceship travelling at the speed of light, 10872.11 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
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.
