65.5 million years ago an asteroid crashed into Mexico and wiped out the dinosaurs.
Including those further north who hadn't the foresight to build a wall.
Too soon?

The South Pole of #Asteroid Vesta
Dawn satellite images reveal a circular structure at Vesta's south pole, possibly from an ancient collision or internal processes. Details may clarify as Dawn captures higher resolution images.

The stellar occultation by (893) Leopoldina is coming up.
On 2025 June 18 at ~00:39 UT the main-belt asteroid will occult TYC 5080-01162-1 (10.9 mag) with a max. duration of 6 s.
24 stations across Europe are ready to observe the event.

Origins of #Water on #Earth May Not Have Started with an #Asteroid Impact
They examined a rare type of #meteorite — known as an enstatite chondrite — that was built similarly to early Earth 4.5 billion years ago and the team discovered hydrogen present in the chemical. The logic is that if this material resembling early Earth's composition can contain hydrogen, so too could the young planet....

"Bright fireball explodes over Nuevo León, Mexico" by TheWatchers (#FPNF Fediverse presence not found - if you know them, invite them) - A bolide lit up the sky around 2am June 15 in northeastern Mexico. A sonic boom was reported, which indicates it was a somewhat larger asteroid than the small ones that hit Earth's atmosphere nearly every day. These are rare in any given location but weekly to monthly somewhere in the world. https://watchers.news/2025/06/15/bright-fireball-explodes-nuevo-leon-mexico-june-15-2025/ #astronomy #asteroid #LowFlyingRocks
Orbits of very distant #asteroid satellites: https://www.aanda.org/articles/aa/full_html/2025/06/aa51124-24/aa51124-24.html -> "The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and long orbital periods, on the order of tens to hundreds of days. The origin of these systems is debatable, and most members of this population are poorly characterized."

Can humanity stop killer asteroids?

Probability of #Asteroid #2024YR4 hitting the #Moon increases
Scientists improve knowledge by 20% thanks to #JamesWebb #Space #Telescope data
#NASA said data from the #JWST "improved our knowledge of where the asteroid will be on Dec. 22, 2032, by nearly 20 percent." The upshot is that there is now a 4.3% possibility that the asteroid will hit the Moon in 7.5 years' time, although it wouldn't alter the natural satellite's orbit.

Y'all, give a little wave to #Asteroid 2008 DG5 tonight as it swings by Earth a safe 9.1 lunar distances away. This lonely rock is ~the size of London's Tower Bridge, orbiting the Sun every 514 days. 0% chance of impact, impossible to see without a decent telescope, but let's wave nevertheless! 🧪🔭

The #multipolygon usage for #meteor #crater mapping in #OpenStreetMap seemed not to be clear, added some examples 🖼️ to the discussion : https://wiki.openstreetmap.org/wiki/Talk:Tag:geological%3Dmeteor_crater#Why_and_when_to_use_a_multipolygon
As already mentioned above, it would make sense if some #asteroid ☄️, #geology or #meteoritics specialists would give their input. The results could also be embedded in #Wikipedia
In case some astronomer has more #telescope time than what they know what to do with, I have a target-of-opportunity #asteroid observable right now: 2013 XV8 (apparent magnitude ~22.1 and rising). Today I've been going through an updated Karman+ mission target list and this guy has appeared there. I love it - Ch type, ~9 hr period (U code is 1 though) and I would love to verify it with more #lightcurve observations.
Hit me up if you have telescope time and want to help / have any questions 🙂
