Comet PanSTARRS Approaches Visibility Peak as It Brightens Toward Perihelion

- Comet C/2025 R3 (PanSTARRS) is brightening in the night sky and could become visible to the naked eye after April 13, with observations in early April showing it at magnitude 6, approaching naked-eye visibility thresholds.
- Light-curve data from the Comet Observation database indicates the comet could brighten to approximately magnitude 4 in coming weeks as it approaches perihelion on April 20, when it will pass within 47.4 million miles from the sun.
- The comet will make its closest approach to Earth on April 27 at approximately 44 million miles distant, with close approaches to the sun typically increasing comet activity and brightness as ice sublimates into glowing gas.
