The International Cloud Atlas or simply the Cloud Atlas, is a cloud atlas that was first published in 1896 [1] and has remained in print since. Its initial purposes included aiding the training of meteorologists and promoting more consistent use of vocabulary describing clouds , which were both important for early weather forecasting .
An example of a Cloud Atlas. A cloud atlas is a pictorial key (or an atlas) to the nomenclature of clouds.Early cloud atlases were an important element in the training of meteorologists and in weather forecasting, and the author of a 1923 atlas stated that "increasing use of the air as a means of transportation will require and lead to a detailed knowledge of all the secrets of cloud building."
C/2024 L5 (ATLAS) is a comet that was discovered on 14 June 2024 as A117uUD by the Asteroid Terrestrial-impact Last Alert System (ATLAS), South Africa, Sutherland. It will reach perihelion on 10 March 2025 at 3.432 AU (513.4 million km ) from the Sun. [ 4 ] [ 5 ]
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.

Astronomers have been discovering weakly hyperbolic comets that were perturbed out of the Oort Cloud since the mid-1800s. Prior to finding a well-determined orbit for comets, the JPL Small-Body Database and the Minor Planet Center list comet orbits as having an assumed eccentricity of 1.0. (This is the eccentricity of a parabolic trajectory ...
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 ...
