TL;DR

Astronomers say the newly spotted Comet C/2025 R3 (Pan-STARRS) could become 2026’s Great Comet, with perihelion around April 20 and Earth flyby around April 27. Brightness is uncertain—estimates range from magnitude 8 (visible with a telescope) to about magnitude 2.5 (visible to the naked eye). The best naked-eye viewing window may be around April 17 near the new Moon, and the comet will be in Pisces near Pegasus as it approaches the Sun; forward scattering could boost brightness if the geometry aligns.
