The universe is full of mysteries, and one of the most intriguing objects that has captured the attention of astronomers and space enthusiasts is the interstellar comet 3I/ATLAS. Last Friday, this celestial body completed its closest approach to Earth without crashing into us or depositing an invading armada.
A Brief History of 3I/ATLAS
3I/ATLAS, also known as C/2019 Y4, was first spotted in December 2019 by astronomers using the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope in Hawaii. The comet was initially thought to be a small, distant object but as it approached Earth, its size and potential impact were assessed.
Initially, astronomers predicted a 1% chance that 3I/ATLAS could impact Earth, which led to increased scrutiny and monitoring of the comet. However, as more data was collected, the chances of an impact decreased to near zero.

The Approach and Aftermath
On May 31, 2020, 3I/ATLAS made its closest approach to Earth, passing within 19.1 million kilometers of our planet. While some astronomers expressed concern about a potential impact, others were studying the comet’s composition and behavior.
Unfortunately, the comet did not provide any significant scientific data, as it was thought to be a relatively small and irregularly shaped object. The lack of detailed observations made it challenging to predict the comet’s behavior and potential risks.
What’s Next for 3I/ATLAS?
After its closest approach, 3I/ATLAS is now moving away from Earth and the solar system. While it’s no longer a threat, its passage has sparked renewed interest in comets and their potential impacts on our planet.
Comets like 3I/ATLAS serve as a reminder of the vast and mysterious universe we inhabit. While we’ve been lucky so far, it’s essential to remain vigilant and continue monitoring celestial bodies to ensure our safety and understanding of the cosmos.
