Beyound Jupiter, The World of Distant Minor Planets: (15810) Arawn

JOA 2021, Vol. 11, No. 4, Page 18

Author(s): Konrad Guhl

Abstract: The Plutino (15810) Arawn was discovered in 1994, orbiting the Sun every 250 years. The orbit is in a 2:3 resonance with Neptune. The diameter is uncertain with estimates ranging from 130–250 km. Observations from the New Horizons spacecraft indicate a rotation period of 5.47 ±0.33 h, and a red colour. No moons have been detected.
