This snapshot shows the overall orbit and current position of Comet C/2025 D1 (Gröller) on March 11, 2025. Note that not all the terrestrial planets are shown.

The comet is expected to possibly be the brightest comet of the year, as it reached a magnitude of -3.4 during its perihelion—brighter than the 0.4 magnitude C/2023 A3 (Tsuchinshan-ATLAS) last year.

Mind you, the hyperbolic nature of 2023 A3’s orbit means that once it rounds the sun, it will never return. This is literally your only chance to see it, so I hope you have clear skies and a ...

On its orbit, the comet will come within 1.18 AU of the sun and stretch as far as 32.64 AU away from the sun. The comet is currently approaching its perihelion — its closest point to the sun.
