Learn how to witness this once-in-a-lifetime celestial event as it graces our skies. Explore the comet’s stunning green glow and find out if it will survive its daring encounter with the Sun. Don’t miss this extraordinary cosmic spectacle!

A recently discovered comet is expected to remain visible to the naked eye until next week. This celestial object, named Comet C/2023 P1 (Nishimura), was first spotted by amateur astrophotographer Hideo Nishimura in Japan using a digital camera on August 11, with 30-second exposures.

Comet Nishimura is currently passing through the constellation Cancer and may continue to be bright enough for viewing in the pre-dawn sky until mid-September. It has already crossed Earth’s orbital path and will pass between Venus and Mercury on its journey around the Sun before eventually heading back into space later this month.

Travelling at an astonishing speed of 240,000 miles per hour, the comet is already visible to the naked eye, as confirmed by Professor Brad Gibson, the director of the E A Milne Centre for Astrophysics at the University of Hull. To spot Comet Nishimura, one can look east-north-east, towards the crescent moon and Venus during the hour after sunset or the hour before dawn.

What makes this comet particularly special is its orbital period of 500 years, in stark contrast to Earth’s one-year orbit and the much longer orbits of outer planets. To put it into perspective, Halley’s Comet, which generated significant interest during its 1986 visit to Earth, takes 76 years to complete its orbit.

Professor Gibson emphasized, “To say this is a once-in-a-lifetime opportunity to see Nishimura isn’t an exaggeration.” However, there’s a caveat – the comet must remain intact as it approaches our Sun. NASA has cautioned that “The comet will get so close to the Sun – inside the orbit of planet Mercury – that its nucleus may break up.” A similar fate befell Comet ISON in 2013 when it disintegrated near the Sun.

Assuming Comet C/2023 P1 holds together, observers should be prepared to rise early around September 11. According to NASA, “As the comet dives toward the Sun, it will undoubtedly intensify and may become a naked-eye object in early September.” However, because of its closeness to the Sun, viewing possibilities may be restricted to times near sunset or sunrise.

Currently, the comet exhibits a bright green glow and a faint coma or tail, which is expected to grow brighter and longer as it approaches the Sun. Comets are composed of dust, rock, and ice, and as they heat up, the ice transforms into gases. Solar winds then disperse these gases and dust from the Sun, creating the characteristic “tail” trailing behind the comet as it approaches.

The origins of C/2023 P1 remain a mystery. Many comets in our solar system are thought to originate from the enigmatic Oort cloud, which is believed to be located between 2,000 and 100,000 astronomical units (AU) from the Sun. For reference, 1 AU is the distance between Earth and the Sun, roughly 93 million miles.

The Oort cloud, though never directly observed, helps explain the presence of comets within our solar system’s planetary region. Voyager 1, the farthest human-made object in space, is still about 300 years away from reaching the Oort cloud, despite travelling at a million miles per day.

If C/2023 P1 originates from the Oort cloud and survives its passage around the Sun, it will likely be centuries before it returns along its elliptical orbit. Alternatively, the comet might be on a hyperbolic orbit, making it a one-time visitor from interstellar space, never to be seen again.
