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]
Isaac Newton, in his Principia Mathematica of 1687, proved that an object moving under the influence of gravity by an inverse square law must trace out an orbit shaped like one of the conic sections, and he demonstrated how to fit a comet's path through the sky to a parabolic orbit, using the comet of 1680 as an example.

The comet was reported to have a nuclear shadow, a dark lane in the tail, and was marginally visible with naked eye on that day. [10] On 7 January the comet was reported to be of first magnitude, with a tail about 20 arcminutes long. [5] The comet was photographed by cosmonaut Ivan Vagner onboard the International Space Station on 10 January. [11]
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however.
Giotto made the closest approach to Halley's Comet and provided the best data for this comet. [17] Giotto was the first spacecraft: to provide detailed pictures of a cometary nucleus. [18] to make a close flyby of two comets. Young and active comet Halley could be compared to old comet Grigg–Skjellerup.
The object had a cigar-like shape and was 750 feet by 115 feet in size, or roughly as large as a skyscraper. ... The object, called 'Oumuamua, is a comet from another star system.
It is estimated that a layer with an average thickness of about 1 ± 0.5 m (3.3 ± 1.6 ft) is lost per orbit as of 2015. [28] The comet has a mass of approximately 10 billion tonnes. [6] The two-lobe shape of the comet is the result of a gentle, low-velocity collision of two objects, and is called a contact binary. The "terraces", layers of the ...
