SUMMARY

The largest known orbit of an object around the Sun is currently attributed to Sedna, with other notable objects including 2000 CR105 and 2000 OO67. Recent observations may have updated the record previously held by HIDALGO. A comprehensive list of comets and their orbits is not readily available, making research challenging. For detailed information, refer to the resources provided by the Institute for Astronomy at the University of Hawaii and the comet database linked in the discussion.

PREREQUISITES
  • Understanding of celestial mechanics
  • Familiarity with orbital dynamics
  • Knowledge of cometary nomenclature
  • Basic skills in astronomical research techniques
NEXT STEPS
  • Research the orbital characteristics of Sedna and its classification as a trans-Neptunian object
  • Explore the latest findings on 2000 CR105 and 2000 OO67
  • Investigate the methodologies for tracking cometary orbits
  • Review the resources available at the Institute for Astronomy for updated comet data
USEFUL FOR

Astronomers, astrophysicists, and space enthusiasts interested in the dynamics of celestial bodies and the latest discoveries in cometary orbits.

What is the largest known orbit of an object around the sun? I searched on yahoo, but nothing.
 
Astronomy news on Phys.org
do a search for HIDALGO its record may have been beaten by
new observations .
 
Sedna, 2000 CR105, 2000 OO67, and "many comets" - according to http://www.ifa.hawaii.edu/faculty/jewitt/kb.html (look in the column marked "Q" for the ones that go furthest from the Sun).

AFAIK, there is no single, reliable list of comets (past and present) and their last known orbits. There are plenty of http://www9.ocn.ne.jp/~comet/ ... happy searching!
