In the Northern Hemisphere, an extraordinary celestial event is approaching: the sighting of a comet that has remained hidden from Earth for more than four centuries.

Named Nishimura after the amateur Japanese astronomer who first spotted it, this unique green comet will come closest to Earth, reaching a distance of 78 million miles, on September 12, as reported by the Associated Press.

To catch a glimpse of this comet in the Northern Hemisphere, you’ll need to wake up approximately 90 minutes before sunrise and direct your gaze north, roughly 10 degrees above the horizon, near the Leo constellation.

The comet will shine more brightly as it draws nearer to the sun but will gradually dim as it descends lower in the sky, the Local12 reported.

While visible to the naked eye, using binoculars will provide a clearer view.

According to Gianluca Masi, an Italian astronomer and the founder of the Virtual Telescope Project, next week represents “the last, practical opportunities” to observe this comet, which hasn’t approached Earth this closely in 430 years.
