BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+25 2497.

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 NGP 25 55, the location is 12h 22m 04.9211 and +25° 06` 20.234 .
Based on the star's spectral type of G6III , NGP 25 55's colour and type is yellow giant star. Based on the star's spectral, the stars temperature is between 5,200.00 and 6,000.00 degrees kelvin.
The Parallax of the star is given as 1.24000 which gives a calculated distance to NGP 25 55 of 2630.35 light years from the Earth or 806.45 parsecs. It is about 15,462,842,250,353,509 miles from Earth.
The star is roughly 166,341,093.92 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.
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.
