The comet C/2023 A3 (Tsuchinshan-ATLAS), often referred to as the “comet of the century,” will reach its peak brilliance and become visible to the naked eye from Earth, particularly in the southern hemisphere, starting tomorrow. Its intense brightness will enable it to stand out prominently in the night sky.
Comets are celestial objects primarily made up of ice, dust, and rock that orbit the Sun. As they draw closer to the Sun, the heat causes the ice to sublimate, which creates a bright atmosphere and often a tail that extends away from the Sun. They are regarded as “visitors” to the solar system, as they typically originate from distant regions such as the Kuiper Belt or, in the case of C/2023 A3, from the Oort Cloud.
The term “comet of the century” signifies that this celestial body has the potential to be the most luminous comet of the 21st century.
The discovery of the comet occurred at the Tsuchinshan Observatory in China in January 2023, and since then, scientists have been studying it to determine its trajectory. They have concluded that it will be visible from Earth between September in the southern hemisphere and October in the northern hemisphere.
In the southern hemisphere, including our country, comet C/2023 A3 has been visible binoculars or other magnification devices since September 18. It will reach its closest point to Earth on October 12, which will enhance its visibility in the northern hemisphere, displaying great luminosity.
In southern hemisphere countries, it will be observable from Friday, September 27 to October 2, when the comet will be at its perihelion, at a distance similar to Mercury’s orbit.
During these days, its brightness will allow it to be seen with the naked eye, as long as observers look up at the right time: around 30 minutes before sunrise in each location where it is visible.
This is because the path of C/2023 A3 is not a specific astronomical event; it will take several days to circle the Sun and move away from the solar system.
The positioning of the star in relation to the comet will allow it to be distinguished in the sky during an approximate period between 5 and 7 in the morning. Experts also recommend finding a location away from light pollution to fully enjoy the event.
It is a non-periodic comet, meaning that its orbit is unpredictable, and it could take between 200 to thousands of years to complete its orbit around the Sun. This rarity makes the opportunity to observe it unique.
Why will the comet be so bright?
As it nears its perihelion, the closest point to the Sun in its orbit, the comet will begin to heat up, leading to the sublimation of the ice, which will contribute to its intense brightness. Experts have noted that the comet’s proximity to the Sun could pose a risk of destruction.
“Despite these predictions, the Tsuchinshan-ATLAS comet appears to be capable of surviving perihelion (its closest approach to the Sun) and will allow us to observe it afterwards,” stated Josep M. Trigo Rodríguez, principal investigator of the Meteorite Group, Minor Bodies, and Planetary Sciences at the Institute of Space Sciences (ICE – CSIC).
Its composition contains a significant amount of dust particles, and its journey through space will create a phenomenon where sunlight reflects off the ice, which rapidly breaks off and forms the comet’s tail, dispersing towards the Earth. This will enable the object to emit brightness comparable to that of the brightest stars in the night sky.
“We understand that this phenomenon plays a key role in the sudden bursts of light observed in some comets,” he remarked.
Studying C/2023 A3 will be vital for science, as these comets are not often visible from Earth and offer valuable information about the origins and evolution of the solar system. By analyzing their composition, structure, and behavior, experts can enhance their understanding of the primordial conditions under which planets and potentially life formed millions of years ago.

Comet C/2023 A3 (Tsuchinshan-ATLAS): The Comet of the Century
What is Comet C/2023 A3 (Tsuchinshan-ATLAS)?
Comet C/2023 A3 (Tsuchinshan-ATLAS), dubbed the “comet of the century,” is set to grace the skies, and it will be visible to the naked eye, especially in the southern hemisphere. Its intense brightness promises to make it one of the most spectacular comets of the 21st century.
Understanding Comets
Comets are celestial bodies primarily composed of ice, dust, and rock that orbit the Sun. As they approach the Sun, the heat causes the ice to sublimate, creating a bright atmosphere and often a tail that extends away from the star. These cosmic travelers are considered “visitors” to our solar system, originating from distant regions like the Kuiper Belt or the Oort Cloud.
The Discovery and Trajectory of C/2023 A3
Discovered at the Tsuchinshan Observatory in China in January 2023, scientists have since studied its trajectory. The comet is predicted to be visible from Earth from late September in the southern hemisphere and into October in the northern hemisphere.
When and Where to See C/2023 A3
In the southern hemisphere, comet C/2023 A3 can be viewed with binoculars or other magnification tools since September 18. It will reach its closest point to Earth on October 12, enhancing visibility in the northern hemisphere as well.
Visibility in the Southern Hemisphere
The comet will be visible from September 27 to October 2, coinciding with its perihelion, where it passes close to the Sun and the orbit of Mercury. The ideal viewing time is approximately 30 minutes before sunrise, ensuring the best chance to spot this bright celestial marvel.
Visibility in the Northern Hemisphere
As the comet approaches the northern hemisphere in October, viewers will enjoy even more favorable viewing conditions. Observations are likely to peak around mid-October.
Viewing Tips
- Look for the comet between 5 AM and 7 AM for optimal visibility.
- Find a location free from light pollution to enhance your view.
- Use binoculars or telescopes for a closer look and a better experience.
Why is Comet C/2023 A3 So Bright?
The extreme brightness of Comet C/2023 A3 can be attributed to its approach to perihelion. As it nears the Sun, its surface heats up, causing the ice to sublimate and creating a glowing atmosphere. Experts contend that even though concerns exist about the comet’s possible disintegration, current analyses suggest it may survive this close encounter.
Scientific Importance of C/2023 A3
Studying comet C/2023 A3 is critical for advancing our understanding of the solar system’s origins and evolution. Non-periodic comets like this one provide scientists with crucial data about the primordial conditions that led to the formation of planets and potentially life. Observing its composition and behavior enables researchers to gather vital insights into the early solar environment.
The Unique Characteristics of Comet C/2023 A3
Composition and Structure
C/2023 A3 consists of a significant amount of dust particles, which plays a crucial role in the visibility of the comet. During its journey, sunlight reflects off the ice, creating brilliant flashes and forming a long tail that fans out as it moves through space.
Potential Risks and Challenges
While some comets disintegrate as they pass close to the Sun, recent assessments of C/2023 A3 indicate that it has a robust structure that should allow it to survive perihelion and provide extended viewing opportunities after its closest approach.
Scientific Implications: A Study in Cosmic History
Observing Comet C/2023 A3 provides scientists the chance to gather data that are often not available from other asteroids or celestial bodies. Understanding such comets will enhance our knowledge of the building blocks of the solar system and the intricate processes that dictate its evolution.
What to Expect When Observing C/2023 A3
Viewers can expect phenomena such as sudden bursts of light as the comet travels through space, leaving a dramatic tail in its wake. The experience is likely to be breathtaking, comparable to witnessing some of the brightest stars against the backdrop of the night sky.
