@orbitalradar.bsky.socialAsteroid 2026 SC13 will pass Earth on 2026-Sep-28, coming within 7.7 lunar distances at 12.4 km/s. That's 2,964,519 km away—close in cosmic terms, but perfectly safe.

@frumpysketch.bsky.socialDay 2641 Asteroids. My robots join the cause to see if they can mine some asteroids and destroy some while they are at it. #asteroids #videogames #robots #frumpysketch
@tchapacan.bsky.socialA space rock the size of a skyscraper just zipped past us at 84,523 km/h. To put that in perspective, 1998 FF14 was cruising at 40 times the distance to the Moon. It’s one of three hazardous visitors passing by our neighborhood today. Space is busy! ☄️

@tchapacan.bsky.socialAsteroid 2019 SH7 is cruising past us today at 34,525 km/h. At its biggest, it’s about the length of a soccer field, yet it’s staying a safe 84 times the distance of the Moon. Space is quiet, but these cosmic travelers are definitely keeping things busy. ☄️
@jmannius.itch.io#20GamesChallenge #Asteroids using #Godot #GodotEngine Making this again is annoying but making notes on tutorials, rather than following along, really helps the learning. Player has lives, and we have a funky game over screen. Almost done #GameDev #SoloDev #IndieDev
@orbitalradar.bsky.socialNext asteroid close approach: 2026 SC flies past Earth on 25 Sep 2026 at ~1.7 lunar distances, around 655,062 km away. Moving at 7.8 km/s, it's a cosmic visitor to track, not fear.

@hydezero-message.bsky.socialPaid guide: work through Atira's slit-loss correction, absorption depth and porosity error propagation. Article exercises clarify the assumptions linking surface minerals to the interior, and how to design follow-up observations.

@hydezero-message.bsky.socialHow can photometry help recover Atira's spectrum? Explore slit-loss correction, CM-meteorite comparisons and continuum choices behind the inference of hydrated minerals. An absorption depth is not a water fraction.

@hydezero-message.bsky.socialCould Atira's rocks retain traces of past water? Corrected visible spectra resemble CM meteorites, suggesting hydrated minerals. The inference depends on slit-loss and continuum choices; it is not a detection of liquid water.

@tchapacan.bsky.socialA massive space rock the size of the Golden Gate Bridge is cruising past us today. At over 50 times the distance to the Moon, 2001 RY47 is just a giant cosmic tourist passing through our neck of the woods. Space is truly humongous. ☄️
@orbitalradar.bsky.socialNext asteroid close approach: 2026 SC will miss us by just 1.7 lunar distances on 2026-Sep-25.
Traveling at 7.8 km/s, it's a spectacular flyby, not a threat. Track its live orbit and distance from Earth at our site.

@tchapacan.bsky.socialSpace rock 2016 LY8 is swinging by today, measuring up to the height of a 40-story skyscraper. It’s staying a safe 34 times the distance of our Moon, moving at a casual 26,000 mph. Just a quiet Friday cruise for our neighborhood cosmic neighbors. ☄️
@ccaf595.bsky.socialNEO follow-up: Amor asteroid 2026 SO12 confirmed at mag 19.6 by our 0.61-m telescope.
Closest approach: Oct 09, 19:07 UT

@stellarvisions.bsky.socialLe vaisseau Dawn, prêt à explorer les mystères de la ceinture d'astéroïdes. 🚀✨
@tchapacan.bsky.socialA giant rock the size of two football fields is zooming past us today at over 100,000 km/h. While it’s technically on the hazardous list, it’s hanging out safely at nearly 200 times the distance to the Moon. Space is wild. ☄️

@tchapacan.bsky.socialA 350-meter space giant is zooming past us today—that’s taller than the Eiffel Tower! While it’s cruising at a safe distance of 190 times the trip to the Moon, its speed is a staggering 78,794 km/h. Space is definitely keeping things busy out there tonight. ☄️
