4179 Toutatis - Wikipedia

WHOOSH

Looks like we had a bunch of near misses recently in the near-Earth asteroid department. A handful passed by with a miss distance closer than the Moon (<1.0 LD in the “Miss Distance” column). I amuse myself by looking up the date of the first observation (by clicking on the Asteroid name in the table). Often these are spotted *after* they've whooshed by.

If any astronomers who look for these things could offer a perspective on how thousands of Starlink satellites etc. are affecting the search, I would love to hear it.

The table is at https://spaceweather.com; scroll down a bit. Clicking on an asteroid name takes you to the JPL Small-Body Database Lookup page (https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/ ) with orbital elements, etc. for the body in question. There is also a nice Solar system orbit viewer there (https://ssd.jpl.nasa.gov/tools/orbit_viewer.html) that can show you a 3-d plot of the solar system and any small bodies you want to show (as long as they are in their database, but it's extensive).

Apparently there was a new #NearEarthAsteroids discovere that could hit us. It's called #2024yr4. Current estimates are at about 1% chance of it hitting the #earth. I know a few places that could use an #meteor strike. ☄️💥

The Earth is getting an extra mini moon for a few weeks… how many times has this happened in the past? The article already points out that this is relatively frequent, as it has happened a number of times since we’ve been tracking near earth objects.

Earth to have new mini-moon for two months

A pair of asteroid dynamics researchers from Universidad Complutense de Madrid Ciudad Universitaria have found that a small asteroid will make one orbit around the Earth starting this month before departing back into other parts of the solar system.

Arecibo Studied 191 Asteroids That Flew Past the Earth. All the Data are Available in a new Paper

Even from beyond the grave, Arecibo is still contributing to new discoveries. Back in October, researchers released a “treasure trove of data” from what was then the world’s most powerful radio telescope on the radar signatures of near-Earth asteroids (NEAs). Not only will these observations help defend the planet if any of those asteroids happen … Continue reading "Arecibo Studied 191 Asteroids That Flew Past the Earth.

Move along, nothing to see here. Nothing's going to happen despite the doomsday proclamations you may have heard. 🙂

"Two asteroids are set to zip past the Earth at relatively close distances over the next couple of months. Despite what you might read in the usual tabloid sites and weird YouTube channels with terrible audio, both are extremely unlikely to hit us."

No, two approaching near-Earth asteroids won’t hit us. 2020, cool your jets.

Two asteroids are set to zip past the Earth at relatively close distances over the next couple of months. Despite what you might read in the usual tabloid sites and weird YouTube channels with terrible audio, both are extremely unlikely to hit us. One is getting a lot of buzz on social media because it may pass us on Nov. 2, the eve of the US election. To me, the cool thing is that the asteroid’s designation is 2018 VP1, so at least that’s mildly appropriate.
