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 .

Physical Properties (Colour) of Scorpius X-1

Scorpius X-1 Colour and Temperature

Scorpius X-1 has a spectral type of Oev E. This means the star is a blue - white star.

Distance to Scorpius X-1

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 is about 63,913,061,706,043,149.40 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.

Time to Travel to Scorpius X-1

A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

If you were to drive there at about 120 m.p.h. in a car with an infinity engine so you didn't have to pull over for petrol, it would take you 532,608,847,550,359.58 hours or 60,800,096,752.32 years.

At the time of writing, the fastest probe so far created is the New Horizon probe which is travelling at a speed of 33,000 m.p.h. If the probe was travelling to Scorpius X-1 then it would take 1,936,759,445,637.67 hours / 221,091,260.92 years to get there. Speed Ref: N.A.S.A.

It would to take a spaceship journey 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.
