🚨 Interstellar Comet Alert! 3I/ATLAS hurtles through our Solar System at 245,000 km/h — the third ever from beyond our Sun!
A cosmic visitor unlike any other has just slid past our Solar System.
What is it?
It’s 3I/ATLAS (officially C/2025 N1), a giant interstellar comet recently confirmed by NASA and the International Astronomical Union.
How fast is it going?
Around 152,000 mph (245,000 km/h)—far too swift to be bound by our Sun's gravity. That high-velocity, hyperbolic trajectory marks it as truly interstellar.
Why it matters:
It’s the third interstellar object ever detected, after 'Oumuamua (2017) and 2I/Borisov (2019).
At up to 20 km across, it may be the largest and brightest interstellar object yet .
Studying it offers a rare glimpse into materials from another star system, potentially unlocking clues about planetary formation beyond our own .
Will it hit Earth?
Not a chance—it will stay at least 1.6 AU away (about 240 million km), well clear of our planet.
When and where to look:
It's currently heading inward, aiming for perihelion around October 30, lying just inside Mars’s orbit. Best viewed through large telescopes through September, then again from December after passing behind the Sun.
