C/2025 R3 (Pan-STARRS) is a newly discovered long-period comet from the distant Oort Cloud that became one of the standout skywatching objects of 2026. First detected by the Pan-STARRS survey telescope in Hawaii on September 8, 2025, the comet swung through the inner Solar System in April 2026, passing just inside Earth’s orbit and briefly becoming visible to the naked eye under dark skies.
