Abstract
We present the Keplerian orbit of S62 around the supermassive black hole Sagittarius A* (SgrA*) in the center of our Galaxy. We monitor this S-star cluster member over more than a full orbit around SgrA* using the Very Large Telescope with the near-infrared instruments Spectrograph for INtegral Field Observations in the Near Infrared (SINFONI) and NAOS+CONICA (NACO). For that, we are deriving positional information from deconvolved images. We apply the Lucy–Richardson algorithm to the data sets. The NACO observations cover data from 2002 to 2018, and the SINFONI data cover 2008–2012. S62 can be traced reliably in both data sets. Additionally, we adapt one KECK data point for 2019 that supports the reidentification of S62 after the pericenter passage of S2. With a period of 9.9 years and a periapse (closest approach) velocity of approximately 10% of the speed of light, S62 has the shortest known stable orbit around the supermassive black hole in the center of our Galaxy to date. From the analysis, we also derive the enclosed mass from a maximum likelihood method to be 4.15 ± 0.6 × 106 M ⊙.

In an abstract published on January 31st of this year (2020), a group of astronomers have announced the discovery of a 2-solar-mass star moving in a highly elongated orbit around the supermassive black hole at the center of our galaxy. The star's orbit is so eccentric that it approaches within 16 astronomical units (within 2.4 billion km) of the black hole's center; more closely than Uranus approaches our Sun.

Conditions are so extreme that at its closest approach, the star is moving at about 10% of light speed, and its orbit precesses roughly 10 degrees per revolution... by far the greatest gravitational precession ever detected. The star's orbit has allowed the astronomers to refine our estimate of the mass of the supermassive black hole Sagittarius A* to 4.15 million solar masses (plus or minus 0.6 million).

the star on crack

defining black hole strength, outrageous

we should call it Charlie Sheen.

Has that any influencew on my horoscope? Not that something changes now.......*shock*

Let's pop Wollensock into orbit and see what happens to the black hole... hehehehhh...

There is a whole solar system, reigned by Spacecat!!
