Comet Wierzchos buzzes the sun later today: But can you see it?

C/2024 E1 (Wierzchos) brightened significantly ahead of its close approach to the sun.

In late April 2026, a long-period comet will swing through the inner solar system. It will likely be visible with binoculars, and there’s a small chance it could be seen with the naked eye.
