Questions about 2060 Chiron
Short answers, pulled from the story.
What is the orbital path of 2060 Chiron around the Sun?
2060 Chiron follows a highly eccentric path with an orbital eccentricity of 0.37 that extends between Saturn and Uranus. Its closest approach brings it inside Saturn's orbit while its farthest point reaches beyond Uranus.
How did James Webb Space Telescope observations change understanding of 2060 Chiron?
The James Webb Space Telescope revealed gas emissions and diverse ices on 2060 Chiron's surface between 0.97 and 5.27 micrometers. Fluorescent methane emissions provided the first evidence of a gas coma rich in this compound alongside carbon dioxide and other volatiles.
Why does 2060 Chiron have rings and when were they confirmed?
Unexpected stellar occultation events on the 7th of November 1993 led astronomers to propose ring structures around 2060 Chiron. Additional data from the 9th of March 1994 and the 29th of November 2011 refined these findings showing rings spanning roughly 280 kilometers in radius.
What are the proposed future missions to study 2060 Chiron?
The Chiron Orbiter Mission was proposed for NASA's New Frontiers program or Flagship program in May 2010 with launch dates ranging from 2023 to 2025. Another mission concept called Centaurus formed part of the Discovery Program if approved for funding to conduct a flyby during the 2030s.
