What was Alan Hale's best known co-discovery formally designated as?
Comet Hale–Bopp Comet Hale–Bopp (formally designated C/1995 O1) is a comet that was perhaps the most widely observed of the 20th century, and one of the brightest seen for many decades.
Coronium Coronium, also called newtonium, was the name of a suggested chemical element, hypothesised in the 19th century. The name, inspired by the solar corona, was given by A. Gruenwald in 1887. A new atomic thin green line in the solar corona was then considered to be emitted a new element unlike anything else seen under laboratory conditions. Because of this it was also mis-classified as Iron Line Number 1474.
