[1] Nessus is a centaur, a dynamically unstable population of minor planets between the classical asteroids and the trans-Neptunian objects.
[15] Fifty clones of the orbit of Nessus suggest that it will not pass within 1 AU (or 150 million kilometers) of any planet for at least 20,000 years.
[16] Nessus was discovered by David Rabinowitz (not officially credited), working with the Spacewatch program, at Kitt Peak National Observatory on 26 April 1993.
[1] This minor planet was named after Nessus, a centaur from Greek mythology, who poisoned and was killed by the divine hero Heracles.
[18] A symbol derived from that for 2060 Chiron, U+2BDC ⯜ NESSUS (), was devised in the late 1990s by German astrologer Robert von Heeren.
[9] The Collaborative Asteroid Lightcurve Link assumes a carbonaceous standard albedo of 0.057 and derives a diameter of 68.48 kilometers based on an absolute magnitude of 9.55.
