Comet C2023-A3, or Tsuchinshan-ATLAS, was pictured about 99.4 million miles away from Earth by NASA astronaut Matthew Dominick using long-duration photography on a camera programmed for high ...
Periodic comets sometimes bear the same name repeatedly (e.g. the nine Shoemaker–Levy comets or the twenty-four NEAT comets); the IAU system distinguishes between them either through the number prefix or by the full designation (e. g. 181P and 192P/Shoemaker–Levy are both "Comet Shoemaker–Levy"). In the literature, an informal numbering ...

The Great Comet of 1577 is a well-known example of a great comet. It passed near Earth as a non-periodic comet and was seen by many, including well-known astronomers Tycho Brahe and Taqi ad-Din. Observations of this comet led to several significant findings regarding cometary science, especially for Brahe.
The comet will make its closest approach to Earth on June 2, when it will be about 144 million miles from our planet and offer another opportunity to see it. By July, it will be too dim to view ...
Comet Swift–Tuttle is by far the largest near-Earth object (Apollo or Aten asteroid or short-period comet) to cross Earth's orbit and make repeated close approaches to Earth. [16] With a relative velocity of 60 km/s, [ 17 ] [ 18 ] an Earth impact would have an estimated energy of ~27 times that of the Cretaceous–Paleogene impactor . [ 19 ]
It's steadily moving away from the Earth after reaching its closest point on Saturday. If you miss this chance, the comet won't return for 80,000 years. Social media users share images of Comet C ...
