The Kepler name comes from the fact that the star was examined as part of the N.A.S.A. Kepler Space Telescope. The telescope operated between March 2009 and October 2018 studying a small section of space for exoplanets around the constellations of Cygnus, Draco and Lyra. After the telescope project came to an end, studies continued with T.E.S.S. space telescope which examined the majority of space for planets.

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 Kepler- 419, the location is 19 41 40.2991192329 and +51 11 05.166046221 .
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 -1.27 milliarcseconds/year towards the north and -0.07 milliarcseconds/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.
