The Brightest Comet of 2025: Comet Atlas C/2024 G3 Lights up the sky
Following the dazzling Quadrantids meteor shower, another celestial spectacle is set to captivate stargazers: the arrival of Comet Atlas C/2024 G3. On January 13, this comet reached its closest approach to the Sun, known as perihelion, and also came nearest to Earth on the same day. Expected to be the brightest comet of 2025, this event is a rare treat for astronomy enthusiasts, especially in the southern hemisphere.

Discovered on April 5, 2024, by the Asteroid Terrestrial-Impact Last Alert System (ATLAS), comet C/2024 G3 originates from the Oort Cloud, a distant region at the edge of our solar system filled with icy remnants from the formation of the planets.During its perihelion, the comet ventured just 13.5 million kilometers from the Sun—closer than Mercury, which orbits at 47 million kilometers. According to the Planetary Society, the comet could shine with a brightness of magnitude –4.5, rivaling the brilliance of Venus.
How Luminous Will It Be?
Scientists classify comet C/2024 G3 as a dynamically old comet, meaning it has orbited the Sun before.Its last close encounter with our star occurred approximately 160,000 years ago,suggesting it may have survived similar conditions in the past.However, the intense heat of this perihelion poses a risk. Nick James, director of the British Astronomical Association’s comet section, explains, “The intense heat might cause it to disintegrate, but if it holds together, it could become a striking sight in the southern hemisphere’s evening sky after it passes the sun.”
How to Observe the comet
For those in the southern hemisphere, Comet C/2024 G3 will be visible shortly after sunset on January 13. Look to the west for the best view.However, observers in the northern hemisphere will face challenges, as the comet will appear very low on the horizon, either just after sunset or before sunrise, and may be obscured by twilight.
Due to its proximity to the Sun, viewing the comet requires caution. Nick James advises that onyl experienced observers attempt to spot it, warning that looking directly at the Sun without proper protective equipment can cause permanent eye damage. The waning phases of the Moon may also add to the difficulty of observation. While the comet might be visible to the naked eye in the southern hemisphere, using binoculars or a telescope is recommended for a clearer view.
For those unable to observe the comet directly, images captured by the Solar and Heliospheric Observatory’s Lasco C3 coronagraph offer an alternative. Resources like the IAU Minor Planet Center or the Comet OBServation (COBS) database can also provide updates and observation details.
Tips for the Best Viewing Experience
To maximize your chances of spotting Comet C/2024 G3, find a dark location away from light pollution. Consider heading to the countryside or organizing a comet-watching event in your community. Set a reminder for the event, and don’t forget to bring warm clothing, blankets, and a pleasant chair for the chilly January night. Avoid looking at bright screens to let your eyes adjust to the darkness, ensuring you don’t miss this cosmic spectacle.
