C/2024 E1 (Wierzchoś) is a hyperbolic Oort cloud comet, discovered on 3 March 2024 by Polish astronomer Kacper Wierzchoś. It will reach perihelion on 20 January 2026, when it could reach an apparent magnitude of +5.
Discovery
[edit ]During a routine Mt. Lemmon survey (G96) search on 3 March 2024, one of the scientists participating in the project, Kacper Wierzchoś, spotted a moving object in four, 30-second exposure images taken using an f/1.6 1.5 m (59 in) Cassegrain telescope, equipped with a 111.5 megapixel (10,560 x 10,560 pixel) CCD. It appeared as a 20th-magnitude object in the constellation Draco, about 2 degrees north of the star ν Dra.[5] Since the discovery announcement, the Zwicky Transient Facility have reported that they obtained precovery images of the comet between 15 and 29 February 2024.[3] The comet was reported to have a condensed coma about 4 arcseconds in diameter and a tail about 6 arcseconds long.[1] [2]
Perihelion
[edit ]The comet will approach perihelion on 20 January 2026 around 18 UT.[6] It will appear about 21 degrees from the Sun and will be visible from the Southern Hemisphere. Peak brightness will reach approximately +5 magnitude, meaning it could be visible through binoculars.[7] It will be about 1.351 AU (202.1 million km; 125.6 million mi) from Earth.[7]
