Heliocentric distance to the descending (thick line) and ascending nodes (dotted line) of 83982 Crantor (2002 GO₉). Saturn’s aphelion, Uranus’ semi-major axis, and Neptune’s perihelion distances are also shown. Both nodal distances are at present relatively close to the value of Uranus’ semi-major axis, which explains why close encounters with Uranus are possible and relatively frequent, but most of the time the asteroid remains at a safe distance from Uranus.
