Astronomers think the object they’ve labeled C/2019 Q4 – discovered August 30 – came from a place far, far away. If confirmed, it’s only the 2nd interstellar object ever detected, after ‘Oumuamua in 2017. Source: https://earthsky.org/space/astronomers-find-2nd-interstellar-object-c-2019-q4…

Astronomers Have Spotted An Interstellar Comet Flying Toward Earth
A comet first spotted by a Ukrainian amateur astronomer looks to be just the second known object to visit our cosmic neighborhood from beyond the solar system. What could be an even bigger deal is the fact that this one was discovered as it’s still approaching us. CNET reports: The comet was found by Gennady Borisov of Crimea on Aug. 30,…
We may have spotted an interstellar comet flying toward Earth

What asteroid Ryugu told us
The Hayabusa2 mission has confirmed that – if asteroid Ryugu or a similar asteroid were to come dangerously close to Earth – we’d need to take care in trying to divert it, lest it break up into fragments that might then impact Earth.

Short Film ‘The Comet’ Uses Real Images From ESA’s Rosetta Space Probe
Launched in 2004, the ESA’s Rosetta space probe spent 10 years flying to the comet Churyumov-Gerasimenko (67p), circled it for two years, and then culminated its mission with a controlled hard landing. Now video artist Christian Stangl and composer Wolfgang Stangl have teamed up to create The Comet, a 3 minute 25 second movie made from digitally-enhanced footage derived from the…
What’s the Difference Between Asteroids, Comets and Meteors?
Look! Up in the sky! It’s an asteroid…. No, it’s a comet…. Wait, it’s neither? Source: https://www.livescience.com/difference-between-asteroids-comets-and-meteors.html
By continuously watching the moon, we could detect interstellar meteorites
When “Oumuamua crossed Earth’s orbit on October 19th, 2017, it became the first interstellar object ever to be observed by humans. These and subsequent observations, rather than dispelling the mystery of “Oumuamua’s true nature, only deepened it. The debate raged about whether it was an asteroid or a comet, with some even suggesting it could be an extraterrestrial solar sail. Source:…

Arecibo gets $19M grant to find and study NEOs
NEOs are near-Earth objects, asteroids and small comets that sweep near Earth and have the potential to cause harm. Arecibo Observatory in Puerto Rico has, since the 1990s, been finding about 60 to 120 of these objects every year. Source: https://earthsky.org/human-world/arecibo-observatory-19-million-grant-neos…
