The location of the giant 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 BP Piscium, the location is 23h 22m 24.7 and -2° 13` 41.4 .
All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -26.30 miliarcseconds/year towards the north and 44.40 miliarcseconds/year east if we saw them in the horizon.
The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -5.80 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.
BP Piscium has a spectral type of G9 IIIe C. This means the star is a white to yellow giant star. BP Piscium lies at a distance of 1,000.00 light years away from our Sun and our planet Earth or to put it another way, 306.59 parsecs away from the Sun.
BP Piscium is an estimated 1,000.00 light years from our Solar System (Earth and Sun). It would take a spaceship 1,000.00 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.
