Trajectory and characteristics of interstellar comet 3I/ATLAS in 2025
NASA has announced the discovery of comet 3I/ATLAS, the third known interstellar object passing through our solar system, originating from outside the Sun’s gravitational influence.
Why it matters: 3I/ATLAS offers rare insight into material from another star system, helping astronomers study the galaxy beyond our solar neighborhood.
Stunning stat: The comet travels at about 137,000 miles per hour and will pass no closer than 1.8 astronomical units from Earth.
The big picture: This is the third interstellar object discovered, following ‘Oumuamua in 2017 and 2I/Borisov in 2019, expanding knowledge of interstellar visitors.
Commenters say: Many express excitement about studying an object from another star system, with curiosity about its composition and origin.
