The star is referred to as HD 319718A with the associated star being referred to as HD 319718B.
The location of the supergiant 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 Pismis 24-1 A (NE), the location is 17h 24m 43.497 and –34° 11` 56.86 .
Based on the star's spectral type of O3.5If* , Pismis 24-1 A (NE)'s colour and type is blue - white supergiant star. Based on the star's spectral, the stars temperature is anything up to -1.00 degrees kelvin. This star is amongst the coldest stars in the universe.
Pismis 24-1 A (NE) has an apparent magnitude of 11.00 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of -0.51 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.
The Parallax of the star is given as 0.50000 which gives a calculated distance to Pismis 24-1 A (NE) of 6523.27 light years from the Earth or 2000 parsecs. It is about 38,347,860,538,127,448 miles from Earth.
The star is roughly 412,526,737.97 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.
