Objects: 333P/LINEAR

Comet 333P/LINEAR will make its closest approach to the Sun on 29 November, at a distance of 1.11 AU.

From Cambridge on the day of perihelion it will be visible in the dawn sky, rising at 22:21 (EST) and reaching an altitude of 69° above the eastern horizon before fading from view as dawn breaks at around 05:37.

The events that comprise the 2024 apparition of 333P/LINEAR are as follows:

Comet brightnesses

Comets are intrinsically highly unpredictable objects, since their brightness depends on the scattering of sunlight from dust particles in the comet's coma and tail. This dust is continually streaming away from the comet's nucleus, and its density at any particular time is governed by the rate of sublimation of the ice in the comet's nucleus, as it is heated by the Sun's rays. It also depends on the amount of dust that is mixed in with that ice. This is very difficult to predict in advance, and can be highly variable even between successive apparitions of the same comet.

In consequence, while the future positions of comets are usually known with a high degree of confidence, their future brightnesses are not. For most comets, we do not publish any magnitude estimates at all. For the few comets where we do make estimates, we generally prefer the BAA's magnitude parameters to those published by the Minor Planet Center, since they are typically updated more often.

Based on the magnitude parameters published for this comet by the BAA Comet Section, we estimate that it may be around mag 11 on 29 November 2024. This estimate is based on observations that the BAA has received from amateur astronomers, assuming that its current level of activity will remain constant.

You will probably require a telescope to see this comet. It is unlikely to be visible through bird-watching binoculars, and even less likely to be visible to the unaided eye.

The comet's position at perihelion will be:

Comet 333P/LINEAR 12h10m50s 36°56'N 10.7
