Comet that could shine as bright as Venus set to be visible from Earth

A surprising comet, named C/2024 G3 (ATLAS), has caught the attention of astronomers with its unexpected brightness as it approaches Earth in the coming days. Initially discovered by NASA’s Asteroid Terrestrial-impact Last Alert System in April last year, the comet was thought to be at risk of disintegration due to its close orbit to the sun. However, recent observations have revealed a new path for the comet, indicating its potential survival and a close encounter with our planet.

This revised orbit, with a cycle of 160,000 years, allows the comet to traverse through the solar system, offering an impressive sight for sky watchers in the southern hemisphere. As it nears the sun, it may also become visible to observers in the northern hemisphere, albeit with binoculars.

Despite initial concerns of fragmentation as it approaches the sun, recent data shows that Comet C/2024 G3 is actually growing brighter, hinting at its intactness and potential for a dazzling display in the night sky. Some experts even speculate that its brilliance could rival that of Venus, making it one of the most luminous comets in recent memory.

However, the exact brightness of the comet remains uncertain. Factors such as its distance from the sun and possible interference from sunlight could impact its visibility. The phenomenon of forward scattering, where dust from the comet enhances its brightness, is also considered a remote possibility by meteorologists.

If the comet maintains its luminosity, it is expected to peak around its closest approach to the sun on January 13 at 10.17am GMT, followed by its nearest pass to Earth shortly after. This presents a prime viewing opportunity for sky gazers in the northern hemisphere from January 12 to 14, particularly in regions like the US and Europe. The best times to observe the comet would be just before sunrise on the 12th and half an hour after sunset on the 14th.
