As the Quadrantids meteor shower fades into memory, skywatchers have another cosmic event to look forward to: the arrival of Comet C/2024 G3 ATLAS. This celestial visitor is set to reach perihelion—the closest point in its orbit to the sun—on January 13, 2025. On the same day, it will also make its closest approach to Earth, potentially becoming the brightest comet of the year. Here’s what you need to know about this captivating astronomical event.
Discovery and Origins
Comet C/2024 G3 was first spotted on april 5, 2024, by the Asteroid Terrestrial-Impact Last Alert System (ATLAS), a network of telescopes designed to detect asteroids that could pose a threat to Earth. Comets like this one originate from the Oort Cloud,a distant region at the edge of our solar system. This icy reservoir is thought to contain remnants of the primordial material that formed the planets billions of years ago.
A Close Encounter with the Sun
When Comet C/2024 G3 reaches perihelion, it will be a mere 13.5 million kilometers from the sun. To put this into viewpoint, Mercury, the closest planet to the sun, orbits at a distance of 47 million kilometers. According to the Planetary Society, the comet could achieve a brightness of magnitude –4.5, rivaling the brilliance of Venus.This makes it a potential naked-eye object for observers in the Southern Hemisphere.
Will the Comet Survive?
The comet’s extremely close approach to the sun raises questions about its survival. Its orbital path suggests it is a dynamically old comet, meaning it has likely made similar journeys in the past. Estimates indicate its last perihelion passage occurred around 160,000 years ago. Nick James, director of the comet section of the British Astronomical Association, notes, “It would be vrey hot and probably not survive. but if it survives, it could become an notable object in the evening sky of the Southern Hemisphere after perihelion.”
How to Observe Comet C/2024 G3
If the comet survives its close encounter with the sun, it will be visible in the southern and western skies shortly after sunset on January 13, 2025. However, its orbital configuration makes it challenging to spot from the Northern Hemisphere, where it will appear low on the horizon and may be obscured by twilight.
Observing the comet requires caution due to its proximity to the sun. James advises,“C/2024 G3 should only be observed if you are an experienced observer.” Directly viewing the sun without proper protection can cause permanent eye damage. Additionally, the waning moon may interfere with visibility, making binoculars or a telescope essential for a clear view.
Option Ways to Experience the Event
for those unable to observe the comet directly, there are other ways to witness this celestial event.The Lasco C3 coronagraph on the Solar and Heliospheric Observatory will capture images of the comet as it approaches the sun. Alternatively, enthusiasts can consult the IAU Minor Planet center or the Comet OBServation (COBS) database for updates and detailed observations.
Final Thoughts
Comet C/2024 G3 ATLAS promises to be a highlight of the 2025 astronomical calendar, offering a rare opportunity to witness a potentially brilliant comet. Whether you’re an experienced stargazer or a casual observer,this event is a reminder of the wonders that lie beyond our planet. Keep your eyes on the skies—or your screens—for a chance to experience this cosmic spectacle.
What makes Comet C/2024 G3 ATLAS so special compared too other comets?
Interview with Dr. Elena Martinez, Astrophysicist and Comet Specialist
By Archyde News Editor
Archyde: dr.Martinez, thank you for joining us today. Comet C/2024 G3 ATLAS has been making headlines as one of the most anticipated celestial events of 2025. Can you tell us a bit about its revelation and what makes it so special?
Dr. Martinez: Thank you for having me! Comet C/2024 G3 ATLAS was frist discovered on April 5, 2024, by the Asteroid Terrestrial-Impact Last Alert System, or ATLAS. this network of telescopes is primarily designed to detect near-Earth asteroids that could pose a threat to our planet. However, it also occasionally spots comets, and this one is particularly interesting.
What makes C/2024 G3 ATLAS so special is its classification as a long-period, sungrazing comet. this means it originates from the distant oort Cloud, a vast reservoir of icy bodies at the edge of our solar system. Its orbit brings it extremely close to the Sun—just 0.09 astronomical units (AU) at perihelion—which is why it has the potential to become incredibly bright.
Archyde: The comet is expected to reach perihelion on January 13, 2025, and could become the brightest comet of the year. What can skywatchers expect to see?
Dr. Martinez: On January 13,2025,the comet will reach its closest point to the Sun,and on the same day,it will also make its closest approach to Earth. This dual event could make it a spectacular sight. current predictions suggest it could reach an apparent magnitude of -3.5, which is brighter than Venus and even some of the brightest stars in the night sky.
For observers in the southern hemisphere, the comet will be visible both before and after perihelion.however, around perihelion, it will be so close to the Sun that it will only be observable in the daytime sky for those in the northern hemisphere. This is a rare opportunity to see a comet during daylight hours, though it will require careful observation and possibly the use of solar filters or telescopes to avoid damaging your eyes.
Archyde: That sounds astonishing! What are the scientific implications of studying a comet like C/2024 G3 ATLAS?
Dr. Martinez: Comets like this are essentially time capsules from the early solar system. They carry pristine materials that have remained largely unchanged for billions of years. By studying its composition, we can gain insights into the conditions that existed when the solar system was forming.
Additionally, because C/2024 G3 ATLAS is a sungrazing comet, it will pass extremely close to the Sun. This allows us to observe how its ices and dust react to intense solar radiation and heat. Such observations can help us understand the processes that shape comets and their tails, as well as their potential role in delivering water and organic molecules to planets like Earth.
Archyde: What advice would you give to amateur astronomers hoping to catch a glimpse of this comet?
Dr. Martinez: For those in the southern hemisphere, the best time to observe the comet will be in the weeks leading up to and following perihelion. Look for it in the pre-dawn or post-sunset sky, depending on its position relative to the Sun. A good pair of binoculars or a small telescope will enhance the view, especially if the comet develops a bright tail.
For northern hemisphere observers,daytime viewing around perihelion will be challenging but not impossible. Use extreme caution if attempting to observe the comet near the sun, and consider joining a local astronomy club or event where professionals can provide safe viewing equipment.
Archyde: what excites you most about this comet?
Dr. Martinez: What excites me most is the unpredictability of comets. while we can make educated predictions about their brightness and behavior, they frequently enough surprise us. C/2024 G3 ATLAS has the potential to be a once-in-a-lifetime event, and I’m thrilled to see how it unfolds. It’s a reminder of how dynamic and awe-inspiring our solar system truly is.
Archyde: Thank you, dr. Martinez, for sharing your expertise with us. We look forward to witnessing this celestial spectacle alongside you!
Dr. Martinez: Thank you! Clear skies, everyone!
