Perihelion on October 29: What to Expect 🌌

On October 29, 2025, the interstellar object 3I/ATLAS will swing around the Sun at its closest point — a moment astronomers call perihelion. During this critical passage, the object will be hidden behind the Sun from Earth, leaving us unable to observe what happens in real time.
So far, 3I/ATLAS has shown all the hallmarks of a comet: a glowing coma, a dust tail, and even water vapor venting into space. But perihelion will be the ultimate test. Will it simply flare up like a normal comet, proving its natural origin? Or could its path change in ways gravity can’t explain — raising new questions about what’s really traveling through our solar system?

This is THE moment of truth at the Sun — and when 3I/ATLAS emerges again, astronomers around the world will be watching closely.
