C/2025 R2 (SWAN) is a long-period comet discovered in September 2025 by Vladimir Bezugly using the SWAN instrument on the SOHO spacecraft, known for its green hue and gas tail, becoming a popular binocular target in late 2025 as it moved through constellations like Virgo and Libra, offering a celestial show even as it faded by early 2026, requiring telescopes for observation.
