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 star is compared to the celestial equator and is expressed in degrees. For WISEPC J205628.90+145953.3, the location is 20h 56m 28.88 and 14° 59` 53.68 .
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 534.00 miliarcseconds/year towards the north and 812.00 miliarcseconds/year east if we saw them in the horizon. . 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.
WISEPC J205628.90+145953.3 has a spectral type of Y0. This means the star is a brown Sub-Brown Dwarf Star.
The Parallax of the star is given as 140.00 which gives a calculated distance to WISEPC J205628.90+145953.3 of 23.30 light years from the Earth or 7.14 parsecs. It would take a spaceship travelling at the speed of light, 23.30 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
The star is roughly 1,472,720.45 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.
