Interstellar Object 3I/Atlas passing through our galaxy in 2025

Interstellar Visitors?

The Internet is a buzz with the news of our third Interstellar visitor, but it’s most likely not an alien spacecraft, just another huge space rock. 

3I/ATLAS is an interstellar asteroid/comet discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile, on 1 July 2025. 

The comet follows an unbound, hyperbolic trajectory past the Sun with a very fast hyperbolic excess velocity of 58 km/s (36 mi/s) relative to the Sun. Astronomers calculate, although it will pass between Earth and Mars, 3I/ATLAS will not pose a threat to Earth. 

This is the third interstellar object confirmed passing through the Solar System, after 1I/ʻOumuamua (discovered in October 2017) and 2I/Borisov (discovered in August 2019),  giving Atlas the prefix "3I".

It would seem that with our recent new and significantly wider view of space, we will undoubtedly spot more and more of these distant space travellers. 

Keep looking up.

October Update: 

Toronto Blue Jays beat the New York Yankees and the went to game seven against the Seattle Mariners. 

Then the Jays took the America League East. Thirty-two years since the last time the Jays won the World Series of Baseball they are in it again!

The LA Dodgers and Toronto Blue Jays battled in what was one of the best and most exciting World Series ever. The Dodgers finally won in a contest that could’ve gone either way.
