Astronomers around the world are trying to track down a small, fast-moving object that is zipping through our solar system.
Is a comet? An asteroid? NASA's not sure. The space agency doesn't even know where it came from, but it's not behaving like the local space rocks and that means it may not be from our solar system.
If that's confirmed, NASA says "it would be the first interstellar object to be observed and confirmed by astronomers."

"We have been waiting for this day for decades," Paul Chodas, manager of NASA's Center for Near-Earth Object Studies, said in a NASA news release.

@edgarblythe,
It's moving fast. Barely enough time to say Aloha before it's gone.

The first one we've been able to spot, to be more precise.

@Olivier5,
Awesome opportunity for study. Where did it originate? How did it come to leave it's home system? Too bad we couldn't intercept it and bring it back for closer study.

Amusingly:

"It was discovered October 19 by the University of Hawaii's Pan-STARRS 1 telescope on Haleakala, Hawaii.

NASA say that on October 14, it safely passed our home world at a distance of about 15 million miles ."

Discovered 5 days later, no wonder my tin hat was playing up.

@TomTomBinks,
What amazes me is how close from us it flew by. I must admit I wondered about whether it was an artifact. Seems just a snowball though.

In theory, comets can be swung outside their star system when they fly near massive planets, which alter their orbit. Supposedly that's what happened here.

@Olivier5,
This proves that objects can get from system to system. Lends more credibility to the panspermia idea.

@TomTomBinks,
Interesting angle... Big fan of panspermia here. :-)

@Olivier5,
Apologies -- it seems to be an asteroid ie a rocky object rather than a comet ie a snowy object.

What is calling me the attention is the hyperbole made by the body.
