Autumn comet imaging success by comet chaser, posing potential visibility through binoculars this autumn season

Newcomer Comet C/2025 K1 (ATLAS), initially spotted in May of 2025, is set to reach its nearest point to the Sun, known as perihelion, on October 8, 2025.

Autumn comet imaging success by comet chaser, posing potential visibility through binoculars this autumn season

The intriguing comet C/2025 K1 (ATLAS) has been capturing the attention of astronomers and stargazers alike since its discovery in May 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS). This celestial body is currently shining at about magnitude +12.5, making it visible to those with a keen eye and the right equipment.

Photographer and comet enthusiast, José J. Chambó, has been capturing images of the comet ahead of its perihelion, which is expected to occur on 8 October 2025. At this point, the comet will be a mere 0.33 AU from the Sun, a distance that places it well within Mercury's orbit.

As it approaches perihelion, the comet faces a high risk of disintegration. After this critical point, it may either disintegrate or become a bright object visible through binoculars in the autumn and winter of 2025.

If the comet survives perihelion, it could potentially be a spectacle to behold in the Northern Hemisphere, reaching a brightness near magnitude +8 and potentially being visible with binoculars. The comet is best seen from the Southern Hemisphere, or southerly latitudes within the Northern Hemisphere.

In the Northern Hemisphere, the comet's potential return towards Earth may occur in the morning sky, making it an exciting sight for early risers. For those interested in photographing this celestial event, a guide on how to do so is available on our website.

It is important to note that there is no information available about who discovered the comet C/2025 K1. The comet's tail extends roughly 20 arcminutes, and its coma is approximately 2 arcminutes wide with moderate central condensation.

If the comet survives perihelion and manages to make its return towards Earth, it could once again be observed, offering another opportunity for stargazers to marvel at this fascinating celestial body.
