Rosetta orbit
A Rosetta orbit is a complex type of orbit.
In astronomy, a Rosetta orbit occurs when an object approaching a black hole with an intermediate velocity enters a complex orbit pattern, bounded by a near and far distance to the hole and tracing an oscillating pattern known as a hypotrochoid. In 2020, scientists using observations made by the European Southern Observatory's Very Large Telescope revealed for the first time that star S2 orbits in this pattern around Sagittarius A*.
In quantum mechanics, the Rosetta orbit is a solution for spherically symmetric potentials.
