C/2025 R3 (PanSTARRS) is a hyperbolic comet originating from the Oort Cloud, discovered on 8 September 2025. The comet reached perihelion on 19 April 2026. Around perihelion the low elevation above the horizon limits practical observing from northern latitudes. Its ion tail was measured at least 7 degrees in length in photographs taken in early April. Closest approach to Earth occurs on 26 April 2026. The comet is classified as hyperbolic, meaning its trajectory is not gravitationally bound to the Solar System. Its future outbound path will result in ejection from the Solar System entirely. The nucleus is estimated to be less than one kilometre in diameter.

Comet C/2023 A3 (Tsuchinshan-ATLAS) has a long tail and can be seen without a telescope. This photo was taken on 14 October 2024, shortly after sunset when the comet was still bright before it fades as it moves further into our solar system.

An exciting object on the very early morning horizon in August/September 2023, comet C/2023 P1 Nishimura. A very short observation window unfortunately, due to its close proximity to the sun. But just enough to make a half hour image of this fast traveller through our solar system.

On 01 February the comet reached its closest proximity to Earth. A few hours of clear skies allowed to capture this moment as a second image

Comet C/2022 E3 (ZTF) is one of the brighter comets this year. It is still increasing in brightness, and while not likely, it could still possibly become visible with the naked eye. This post describes the image itself and also contains an animation of the comet moving across the backdrop of the stars.

Bright comets are seldom appearances in our solar system. Comet Leonard was one of the most striking examples this year. Just days before it would become at its brightest and before it would cross the ecliptic, this image was shot in the early morning hours.

One of the brightest and largest comets in a long time, comet Neowise. A spectacular object, photographed using a regular photo camera with telelens.

At one point comet 46P Wirtanen was promising to become a spectacular event. In the end it turned out to be a modest performance. See here a photo and video.
