Interstellar Comet Nears Earth!
16 Dec, 2025
Summary
- Interstellar comet 3I/ATLAS will make its closest approach to Earth on December 19.
- Scientists are studying the comet to learn about materials from other star systems.
- Despite theories, NASA confirms 3I/ATLAS poses no threat and is not alien technology.
The interstellar comet 3I/ATLAS is currently nearing Earth, with its closest approach scheduled for December 19. This unique celestial body, confirmed in July 2025 as originating from outside our solar system, travels at an astonishing speed of 137,000 mph. Its trajectory is hyperbolic, meaning it will eventually leave our solar system, making it a rare visitor.
Scientists are keenly observing 3I/ATLAS, utilizing powerful instruments like the Hubble and James Webb Space Telescopes. They aim to analyze materials that formed in a different star system, offering unprecedented insights into cosmic origins. The comet's nucleus is estimated to be between 1,400 feet and 3.5 miles in diameter.
Despite some popular speculation, including theories of it being an alien spaceship, NASA officials have dismissed such notions. They affirm that 3I/ATLAS poses no danger to Earth and exhibits no evidence of extraterrestrial technology. The comet, while not visible to the naked eye, can be observed through telescopes until spring 2026.
