Living and learning on the land and under the skies of Treaty 4 (Saskatchewan, Canada).

Thanks to Saskatchewan's beautiful night sky, my research background in small body orbital dynamics, and a couple of really unfortunately placed SpaceX reentries, I spend a lot of time yelling about satellite pollution in international news media.

New dwarf planet!

AkaSci 🛰️ @AkaSci@fosstodon.org · open

The Vera C. Rubin Observatory has discovered a new Dwarf Planet candidate in our solar system - 2026 ED138, a large, bright trans-Neptunian object orbiting beyond Pluto.

Distance from Sun: ~46 au (1 au is the average distance between the Earth and the Sun. Pluto has an average distance of 40 au)
Orbital tilt: 25°
Diameter: 600 - 1500 km

If confirmed, ED138 would be among the largest dwarf planets ever discovered in this region of the Solar System.

Good moonrise, good dogs.

Our planet is really a neat one. Worth fighting for.

2 large fluffy light-coloured dogs in a hayfield, with the full moon rising over the edge of the very flat horizon. The Earth's shadow is just rising above the horizon, meeting the moon with a band of pink/purple.
