Get ready for an astronomical event! On September 12, 2023, Comet Nishimura, also known as Comet C/2023 P1 (Nishimura), will pass by Earth at a distance of 125.4 million kilometers (77.9 million miles). The best part? You don’t need any fancy equipment to witness this celestial wonder. It will be visible to the naked eye, so grab a blanket and prepare for some stargazing.
Comet Nishimura has already been spotted by keen-eyed observers since August 11. Amateur astronomer Hideo Nishimura, the namesake of the comet, has an impressive track record, having discovered two other comets in the past. If you haven’t seen it yet, talented astrophotographers have captured stunning images of the comet, showcasing its vibrant green color and long thin tail.
Don’t miss out on this once-in-a-lifetime opportunity! Comet Nishimura will reach its perihelion, the closest point to the Sun, on September 17. After that, it will become much harder to observe. So, if the skies are clear tomorrow morning, make sure to seize your chance.
If you’re in the UK, the best time to see the comet is just before dawn on Tuesday, between 4 am and 6 am. While it may be visible to the naked eye, using a pair of small binoculars will enhance your viewing experience.

Comet Nishimura is not the only green comet to grace our skies. Earlier this year, C/2022 E3 (ZTF) made its closest pass to Earth in 50,000 years, providing stunning photo opportunities.
Here’s the catch: Comet Nishimura won’t be visible again until 2431, a time period that even many sci-fi franchises dare not explore. So, set your alarm a couple of hours early tomorrow and witness this celestial spectacle for yourself. It’s a rare event you won’t want to miss.
