Circinus X-1 has alternative name(s) :- BR Circinus.
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 Circinus X-1, the location is 15h 20m 40.85 and -57° 10` 00.1 .
Circinus X-1 has a spectral type of B5-A0. This means the star is a blue star. Circinus X-1 lies at a distance of 31,000.00 light years away from our Sun and our planet Earth or to put it another way, 9,504.44 parsecs away from the Sun.
Circinus X-1 has an apparent magnitude of 21.40 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
Circinus X-1 is an estimated 31,000.00 light years from our Solar System (Earth and Sun). It would take a spaceship 31,000.00 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.
