Abstract: Test of the gravity theory near the Galactic center massive black hole candidate Sgr A* has just begun using the pericenter passage of the star S0-2 (or S2) in 2018. The non-Newtonian effect was detectable in the spectroscopic observation of the event (the observation of the redshift of photons coming from S0-2). We, Japanese group, assess the difference between the predictions of Einstein gravity (general relativity, GR) and Newton gravity (NG), while American and European groups assess the hypothesis that the GR is true. If the GR is favored by two different approaches, then the GR can be favored more definitely than the case using only one approach. Our results obtained by 2018 are published in Saida et al. (2019).
