What comet will be visible in 2023?
The following chart shows the distance of Comet C/2023 A3 (Tsuchinshan-ATLAS) from Earth as a function of time. It’s about every 20 years or so that we do get a comet that’s visible to the unaided eye,” he explained. It was first discovered back in January of 2023 by an observatory in China, and then later confirmed to be a comet by the ATLAS group, earning it the name C-2023 A3 Tsuchinshan-Atlas.The comet was named for both observatories. Based on its orbital trajectory, astronomers estimate it visits the inner solar system once every 80,000 years. The life cycle of Tsuchinshan-ATLAS is so long that it has visited the Earth only three or four times since the birth of humanity.Comet Tsuchinshan-ATLAS, also known as C/2023 A3 to scientists and pronounced Choo-cheen-shahn, is expected to be visible to the naked eye across the Northern Hemisphere for several weeks in October, with the best opportunity between Oct. NASA.If a comet survives when it approaches the sun, it gets warmer. The heat from the sun causes the ice to sublimate into gas and these gases and dust become a glowing coma and tail that can extend millions of miles. In the case of Tsuchinshan-ATLAS, it’s believed to be as long as 18 million miles.
When to see comet c 2023 A3?
By the end of September 2024 it became a morning object and reached perihelion – the closest point to the Sun in its orbit – on 28 September 2024. Our best views of A3 are now, as it moved up into the evening sky around 10 October. Based on orbital calculations, astronomers believe it could be another 80,000 years before the comet is visible again, and that’s only if it survives its voyage around the solar system. Skygazers in the Northern Hemisphere can still catch a fading glimpse of this exit for the next several days just after sunset.October 9, 2024–October 12, 2024 However, because the comet will be extremely low to the horizon, looking through that much air plus being in so much sunset glare might counteract much of that visual brightness bump. It will also only be above the horizon for about 15 minutes or so after sunset before it sets.Although C/2023 A3 will certainly be visible to the naked eye, it remains to be seen if its brightness overtakes the record of any previous naked-eye comet. These cautions aside, avid space enthusiasts shouldn’t blow away their chance to send off this unearthly visitor.The next comet to reach perihelion is C/2025 A6 (Lemmon), which should become easy to spot with binoculars from the Northern Hemisphere in late October. We’ll keep you updated on all the news about upcoming comets.The best way to find the comet is to first locate Venus. Venus is visible in the southwest 20 minutes after sunset. On October 14, 2024, C/2023 A3 (Tsuchinshan-ATLAS) will be found about 22° north of Venus.
What time is ATLAS comet visible?
October 9, 2024–October 12, 2024 However, because the comet will be extremely low to the horizon, looking through that much air plus being in so much sunset glare might counteract much of that visual brightness bump. It will also only be above the horizon for about 15 minutes or so after sunset before it sets.

Skygazers in the Northern Hemisphere can still catch a fading glimpse of this exit for the next several days just after sunset.People in the southern hemisphere have already had a glimpse of Comet A3, but from now it can also be seen in the northern hemisphere. There will actually be two windows to spot it. First, between 27 September and 2 October, when it will be visible east just before sunrise, and then again between 12 and 30 October.You can spot it looking west-southwest, with the best viewing time around 45 minutes after sunset. This is when the comet, moving slowly toward the horizon, is illuminated by the sunset, showcasing its long, wispy “anti-tail.The brightest comet in over a decade is still visible in the night sky! C/2023 A3 (Tsuchinshan-ATLAS) is fading away, leaving the inner Solar System, but if you grab a pair of binoculars, you can still catch it in the evening over the western horizon.If you want to see comet C/2024 G3 (ATLAS), you’re going to need to find somewhere with a clear, unobstructed view of the horizon slightly to the south of due west.
Will a comet hit Earth?
The chance of a comet or asteroid of this size hitting us is extremely small – it’s estimated to happen around once every 10 million years. The Vredefort impact event, which occurred around 2 billion years ago in Kaapvaal craton (what is now South Africa), caused the largest verified crater, a multi-ringed structure 160–300 km (100–200 mi) across, forming from an impactor approximately 10–15 km (6.Although an asteroid or comet in Earth’s cosmic neighborhood is nothing new, the comet—known as 2014 UN271—is much larger than most: At between 100 and 370 kilometers wide, it dwarfs the 10-kilometer-wide asteroid that wiped out the dinosaurs 65 million years ago.The Chicxulub impactor At the end of the Cretaceous Period 66 million years ago, an asteroid the size of a city collided with Earth. The Chicxulub impactor, as it is called, was somewhere between 10 and 15 kilometres in diameter.
Did Comet Tsuchinshan-Atlas break up?
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. The Sun’s heat causes the comet’s ices to change to gases so the coma gets larger. The coma may extend hundreds of thousands of kilometers. The pressure of sunlight and high-speed solar particles (solar wind) can blow the coma dust and gas away from the Sun, sometimes forming a long, bright tail.Although we don’t know the exact cause of Comet ATLAS’s breakup, it’s likely that solar heating at perihelion caused intense jetting and outgassing from the nucleus, leading to fragmentation. For all their solid external appearance, comets are fragile, porous and subject to disruption.Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth’s diameter, while the tail may stretch beyond one astronomical unit.Comets form from a nucleus of dust, water, and gas in the farthest-known regions of our Solar System. This close-up of the Comet C/2024 G3 (ATLAS) cleanly shows the vaporized material of the nucleus creating the iconic cometary shape.
