A rare pair of nomads from the depths of outer space are set to visit us this October! Are they aliens? Don’t worry, it’s not (though that would be fun!). Our mysterious travelers are none other than Comet C/2023 A3-Tsuchinshan and Comet C/2024 S1-ATLAS, and they’re getting ready to light up the night sky. We know our readers are quite smart—”soon” for astronomers can mean anywhere from hundreds to thousands of years. But luck is on our side this time because these cosmic spectacles will grace our skies this very autumn—specifically, in October!

Before we dive into the what and how, let’s get to know this icy wanderer with some fun facts:

    • Did you know? Comets C/2023 A3-Tsuchinshan and C/2024 S1-ATLAS were only recently identified, making their visits all the more intriguing.
    • Fun Fact: Comets are commonly referred to as “dirty snowballs” because of their composition of ice, dust, and rock. But trust me, this one is far from dirty—it’s a sparkling light display!
    • Wait, what? Some comets take thousands of years to complete one orbit around the Sun. You’re witnessing a cosmic nomad who has been on the road for a long, long time.
    • Why now? Comets like C/2023 A3-Tsuchinshan and C/2024 S1-ATLAS don’t visit Earth often, so this is one for the books. You can brag about seeing them for years!
    • When? Comet C/2023 A3-Tsuchinshan comet is expected to reach its peak visibility in mid-October 2024. On the other hand, Comet C/2024 S1-ATLAS will have its peak visibility in late October 2024.

Comets: Nature’s Cosmological Wanderers

 

After a quick overview of these comets, let’s go deeper. For centuries, humans have been fascinated by comets. These ice wanderers are composed of frozen gases, dust, and rocky particles. They follow an elongated elliptical orbit As they get closer to the sun, the frozen surface starts to vaporise, producing a bright coma and lovely tails. They can be several kilometres or tens of kilometres wide. A comet has two tails that get longer as it moves closer to the sun. Both tails always point away from the Sun. The ion tail (blue) always points directly away from the Sun, whereas the dust tail (yellow) does so in a slightly different direction.

The Life Cycle of a Comet

Comets typically originate from two primary regions in our solar system: the Kuiper Belt, located beyond the orbit of Neptune, and the Oort Cloud, a distant spherical shell surrounding the solar system. 

While some comets have predictable orbits and return regularly, others, like C/2023 A3-Tsuchinshan and C/2024 S1-ATLAS, are non-periodic and may only visit our inner solar system once, making their appearances incredibly special. The names of these comets are defined by the International Astronomical Union (IAU).

Are Comet C/2023 A3-Tsuchinshan and Comet C/2024 S1-ATLAS the Only Comets to Ever Visit Us?

The answer is no! While the visits of these nomadic icy bodies are indeed rare, they are far from the only comets to grace our skies. Numerous comets have passed by Earth throughout history, some becoming famous for their stunning displays and others for their infrequent appearances. As our observational technology improves, we continue to discover new comets, each presenting an exciting opportunity for skywatchers and astronomers alike.
