See it on NASA's siteComet Nishimura, C/2023 P1, was discovered just ten days ago by Hideo Nishimura using a standard digital camera. It is currently brightening and is expected to become visible to the unaided eye as it approaches the Sun. Its path through the inner Solar System has been determined, and astronomers are watching its continued intensification.
