Understand

Two recent papers (Ghez et al.

2008, Gillessen et al.
2009) have estimated the mass of and the distance to the massive black hole in the center of the Milky Way using stellar orbits.
The two astrometric data sets are independent and yielded consistent results, even though the measured positions do not match when simply overplotting the two sets.
