The systematic search performed by the Asteroid Terrestrial-impact Last Alert System detected an asteroidal object with an estimated magnitude of 18.1 in images taken on 22 February 2023 using the 0.5 m f/2 Schmidt reflector at the Sutherland Observatory in South Africa, when the comet was about 7.3 AU (1.09 billion km; 680 million mi) from the ...
The object – which has the full name C/2023 A3 (Tsuchinshan–ATLAS) – was found last year but in recent weeks has passed close enough to Earth that it could be seen with the naked eye. The ...

The position of comet C/2023 P1 (Nishimura) in the starry sky in September 2023: - On September 1 at an apparent magnitude of 6.5 m in the upper right corner of the constellation Cancer. - From September 7 to 9 at an apparent magnitude of just over 4 m half to the upper right in the head of the constellation Leo.
The object orbits the Sun but makes slow close approaches to the Earth–Moon system. Between 29 September (19:54 UTC) and 25 November 2024 (16:43 UTC) (a period of 1 month and 27 days) [4] it passed just outside Earth's Hill sphere (roughly 0.01 AU [1.5 million km; 0.93 million mi]) at a low relative velocity (in the range 0.002 km/s (4.5 mph) – 0.439 km/s [980 mph]) and became temporarily ...
C/2023 V4 (Camarasa-Duszanowicz) is a hyperbolic comet that was discovered on November 5, 2023, by two astronomers Jordi Camarasa from Sabadell in Spain and Grzegorz Duszanowicz from Akersberga, Sweden, using Duszanowicz's two 280mm aperature, f/1.9 Schmidt-Cassegrain (Celestron C11) telescopes, located at Duszanowicz's "Moonbase South ...
