The orbit of S2 is shown to precess as general relativity predicts
node
The GRAVITY collaboration reported that the orbit of S2 does not close: its pericentre advances from orbit to orbit by the amount general relativity predicts for the Schwarzschild geometry. It is the same class of effect as the anomalous precession of Mercury that supported general relativity in 1915, measured in a field vastly stronger, around an object four million times the mass of the Sun. The measurement also constrains any extended mass distribution inside the orbit.
A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
