Centaurs are small bodies in the solar system that have the characteristics of both asteroids and comets. It is estimated that there are about 50,000 centaurs in the solar system with a diameter of more than 1 kilometer; as of 2017, 408 centaurs have been discovered. Centaur Nessus revolves around the Sun in an orbit with a semi-major axis of 24.5 AU. e. Find the period of Ness’s revolution around the Sun. Eccentricity of Ness’s orbit is 0.518. Between which orbits of the major planets is Nessus moving?

T = √24.53 ^ 3 = 121 years. Perihelion distance q = a (1 – e) = 24.5 (1 – 0.518) * 11.8 a. e. Aphelion distance Q = a (1 + e) = 24.5 (1 + 0.518) = 37.2 a. e. Nessus revolves outside the orbit of Saturn. Intersection with the orbits of Uranus, Neptune.
