Comet P1 Nishimura will fly past Earth in September 2023, and it is expected to be visible to the naked eye.

The September 2023 comet was discovered by Japanese amateur astronomer Hideo Nishimura.

At the time of discovery, the comet had an apparent magnitude of 10.4, or about 40 times fainter than a star on the threshold of naked-eye visibility.

The comet is brightening as it approaches the Earth and the Sun. As of August 26, its magnitude had skyrocketed to 7.9, a ten-fold increase in brightness as compared to the night it was discovered.
