@orbitalradar.bsky.socialNext asteroid close approach: 2026 SY flies by at 5.5 lunar distances on 2026-Sep-21. That's ~2,131,541 km away, zooming past us at 9.8 km/s — safely distant but thrilling to track.
Live data shows its distance and orbit: orbitalradar.com/asteroid/2…
@tchapacan.bsky.socialA massive space rock the size of two football fields is cruising by today, but don't worry—it’s staying a safe 127 times further away than our Moon. Meanwhile, a smaller rock is zipping past at over 65,000 km/h. Space is busy, but we're perfectly safe. ☄️
@tchapacan.bsky.social2012 RL15 is tearing through the void today at 64,823 km/h. At about the size of a tennis court, this space rock is cruising by at roughly 97 times the distance to the Moon. Just another busy Sunday in our corner of the solar system ☄️
@orbitalradar.bsky.socialNext asteroid close approach: 2026 SK on 2026-Sep-19, at ~4.3 lunar distances — 1,652,398 km from Earth.
It'll speed by at 16.2 km/s. Safe but close enough to marvel.

@tchapacan.bsky.socialA space rock the size of a football stadium is cruising past us today at 66 times the distance to the Moon. Meanwhile, a smaller visitor is zipping by at nearly 30,000 km/h—roughly 50 times the lunar gap. All five of today's flybys are safely in the distance. ☄️
@orbitalradar.bsky.socialNext asteroid close approach: 2026 RF15 on 2026-Sep-19. It's 5.5 lunar distances away, speeding by at 14.1 km/s.

@stellarvisions.bsky.socialUn monde extraterrestre mystérieux entouré d'astéroïdes. 🌌🌠
@tchapacan.bsky.socialAn absolute giant is cruising past today! 2017 XD, a rock potentially twice the height of the Burj Khalifa, is hurtling through space at a staggering 133,396 km/h. It’s safely out at 125 times the Moon’s distance, but that is one serious cosmic speed demon. ☄️

@tchapacan.bsky.socialAsteroid 2019 GM1 is buzzing by today at 33 times the Moon's distance. At about the size of a school bus, it's just a pebble in the cosmic ocean compared to 2006 SB142, a space rock the height of a skyscraper cruising much further out in the dark. ☄️
