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 2M 0103-55 (AB), the location is 01h 03m 36.00 and -55° 15` 56.16 .
2M 0103-55 (AB) has a spectral type of M. This means the star is a red star.
The star is believed to be about 0.03 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.
The Parallax of the star is given as 21.19 which gives a calculated distance to 2M 0103-55 (AB) of 153.95 light years from the Earth or 47.20 parsecs. It would take a spaceship travelling at the speed of light, 153.95 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
The star is roughly 9,735,631.02 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.
