The comet can be seen in the western sky about 30 to 45 minutes after sunset through about Oct. 31. The comet C/2023 A3 Tsuchinshan–ATLAS is seen near the western horizon over the Millers ...
48P/Johnson is a periodic comet in the Solar System. The comet nucleus is estimated to be 5.74 km (3.57 mi) in diameter by Lamy, Fernandez, and Weaver. [ 2 ] Meanwhile, David C. Jewitt and Scott S. Sheppard estimate the nucleus to have dimensions of 6.0 × 4.4 km (3.7 × 2.7 mi).
A bright comet has made a rare appearance in the sky, and skywatchers will have several opportunities to see it before it retreats into the icy depths of space. Comet C/2023 A3, also known as ...
Comet Tsuchinshan-ATLAS is expected to come within approximately 44 million miles of Earth on Saturday. Comet visible with naked eye in sky this weekend comes around only every 80,000 years Skip ...
The nucleus of the comet was found to rotate every 8.5 [8] to 8.7 hours. [9] In the spectrum of the comet in the wavelength range between 5000 and 7000 Å many emission lines of NH 2, C 2, and [OI] are detected. [36] [37] The spectrum of the comet was obtained on 10 March 2023 and lines associated with CN, diatomic and triatomic carbon and ...
As the comet warms, parts of it sublimate; [1] this gives a comet a diffuse appearance when viewed through telescopes and distinguishes it from stars. The word coma comes from the Greek κόμη (kómē), which means "hair" and is the origin of the word comet itself. [2] [3] The coma is generally made of ice and comet dust. [1]

17P/Holmes is a periodic comet in the Solar System, discovered by the British amateur astronomer Edwin Holmes on November 6, 1892. In only 42 hours in October 2007, the comet brightened from a magnitude of about 17 to about 2.8. This represents a change of brightness by a factor of about a half million times, and is the largest known outburst ...
