Summary
- Comet C/2025 R3 (PanSTARRS) will be visible before sunrise until April 21.

- Comet R3 PanSTARRS orbits the sun approximately every 170,000 years.
A newly discovered comet, C/2025 R3 (PanSTARRS), is set to make a temporary appearance in the Northern Hemisphere's sky. This celestial object, which has been traveling in our solar system since September, will be visible for a short period before sunrise each day until April 21. Observers can look forward to its closest approach to Earth on April 26, when it will be approximately 45.5 million miles away.
During its closest approach, comet R3 PanSTARRS is predicted to reach its maximum brightness, potentially making it visible without optical aid. The comet's path will take it between Mercury and Venus in the final days of April. This rare visitor has an estimated orbital period of about 170,000 years around the sun and was initially detected in September 2025 by the Pan-STARRS survey located in Hawaii.
For optimal viewing of comet C/2025 R3, sky watchers are advised to scan the lower eastern sky with binoculars approximately 90 minutes before sunrise. The comet is expected to brighten significantly as it nears perihelion, its closest point to the sun, around April 19-20. This event offers a unique chance to witness a long-period comet before it embarks on its distant journey.
