A rare example of the opposite—positive effects arising from Earth encountering a comet—appears in H. G. Wells's 1906 novel In the Days of the Comet: the gases in the comet's tail alter the atmosphere in a way that transforms human character for the better. [1] [2] [4]: 119 [6]
Coin showing Caesar's Comet as a star with eight rays, tail upward. Non-periodic comets are seen only once. They are usually on near-parabolic orbits that will not return to the vicinity of the Sun for thousands of years, if ever.
This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...
The confirmation of the comet's return was the first time anything other than planets had been shown to orbit the Sun.

Comet Kohoutek (formally designated C/1973 E1 and formerly as 1973 XII and 1973f) [c] is a comet that passed close to the Sun towards the end of 1973. Early predictions of the comet's peak brightness suggested that it had the potential to become one of the brightest comets of the 20th century, capturing the attention of the wider public and the press and earning the comet the moniker of "Comet ...
