Once upon a time…….
….there was a young telescope and a young astronomer.

5145 Pholus (and friends)
• Discovered in 1992 (5145) Pholus joined 2060 Chiron as the 2nd known Centaur (outer planet crossing) object.
• UKIRT service observations at JHK confirmed optical observations that it was very red with V-J= 2.58
