Geminga is a Pulsar that can be located in the constellation of Gemini. The star can not be seen by the naked eye, you need a telescope to see it.
More details on star alternative names can be found at Star Names.
The location of the star in the galaxy 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 Geminga, the location is 06h 33m 54.5 and +17° 46` 12.9 .
Geminga is an estimated 815.00 light years from our Solar System (Earth and Sun). It would take a spaceship 815.00 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.
