Most anticipated comet of the year to make its closest approach to Earth this weekend

A once-in-80,000-year sight will make its closest approach to Earth this weekend before heading into the vast abyss of outer space. 

Comet C/2023 A3 Tsuchinshan-Atlas made its closest approach to the Sun in September and will come within 44 million miles of Earth. 

Due to its proximity, the celestial object will appear in the western sky after sunset each evening until around mid to late month.

“Comet C/2023 A3 is no threat to Earth,” Peter Veres, a research scientist at the Minor Planet Center, previously told FOX Weather. “We know the comet’s orbit well. The orbit is becoming better and better with more and more astrometric observations incoming to our center – the MPC.”

The celestial object was only recently discovered in 2023 when observers at China’s Tsuchinshan Observatory were conducting routine monitoring.

Astronauts aboard the International Space Station have also observed Tsuchinshan-Atlas comet on its journey around the Sun.

The space station captured a photo of the comet on September 19, showing its dusty tail in the vast darkness of outer space.

Astronomers say the closer a comet gets to the Sun, the longer the tail tends to grow.

Comets are simply the remnants of the solar system’s formation, which took place approximately 4.5 billion years ago and are composed of a mixture of ice, dust, rock and gases.

“Some comets do not survive close encounters with the Sun. If they get too close, radiation and gravitational forces may disintegrate them completely. Tsuchinshan-ATLAS did not suffer this fate, but another comet astronomers were watching, C/2024 S1 ATLAS, may have,” NASA stated.

The celestial feature will likely be visible until the next Full Moon cycle approaches, which is the Full Hunter’s Moon on Oct. 17.

Based on orbital calculations, astronomers believe once the comet leaves Earth’s sight, it could be another 80,000 years before the comet is visible again if it survives its voyage around the solar system.

If you miss the Tsuchinshan-Atlas comet, not too many celestial events are left in the calendar year, with three Full Moons and a close bypass with Jupiter, which will all occur before the winter solstice.
