  In three previous papers I showed that the series of the midpoints of the
times of all the X-ray flares of Sgr A* that have been detected so far harbor a
statistical trend termed pacemaker regularity. This means that X-ray flares are
detected more frequently around time points that are a subset of a periodic
grid on the time axis of period P_X=0.1032 day=149 minutes. The series of the
times of detection of the peaks of near IR (NIR) flares of the object are also
regulated by a pacemaker with a period of P_IR=0.028 day=41 minutes. Here, I
show that the series of the midpoints of the times of recorded NIR flares are
also regulated by a pacemaker of the period P_IRM=0.039 day=56 minutes. The two
pacemakers found in the previous papers were interpreted as signals of a star
that revolves around the black hole of Sgr A* in orbit with a mean radius of
~3.2 Schwarzschild radii of the black hole, here corrected to ~3.13. The
finding of the period of the third pacemaker is consistent with the suggested
revolving star model. Here, I present the specific orbit of the star as well as
a plausible description of its sidereal rotation. The model also implies that
the star has an unusual internal structure. I show that the discovery of the
GRAVITY collaboration of the motion of hotspots at distances from the black
hole that are of the order of very few Schwarzschild radii of it may well be
understood within the context of the revolving star model.
