Interstellar Visitor: 3I/ATLAS Nears Sun — Scientists Brace for Unknowns
Astronomers around the world are now closely watching the interstellar object 3I/ATLAS, which is approaching its closest point to the Sun (perihelion). While its behaviour is largely comet-like, with sublimation and tail formation, some researchers have flagged its unusual trajectory and composition — prompting speculative debate about whether we are witnessing a genuinely novel type of object.
The object, first confirmed by NASA in early July 2025, is one of only three interstellar objects ever detected in our solar system. As 3I/ATLAS draws nearer to the Sun, scientists expect a surge of gas and dust emissions — and the possibility that its structure may fragment or evolve in surprising ways. According to reports, its closest approach will be roughly 1.4 astronomical units (≈210 million km) from the Sun.
What makes it especially intriguing: some set-of observers, including Avi Loeb, suggest that its behaviour (jet directions, speed, composition) might hint at something beyond a typical cometary body. While mainstream science remains cautious, the intrigue is capturing public imagination.
Why it matters
A rare opportunity to study material from outside our solar system, offering insights into other star systems.
Potential to enhance our understanding of comet-dynamics under intense solar heating.
Raises questions about the nature of small interstellar objects, and whether current models fully account for them.
