2023 Aug 7: 50000 Quaoar, Weywot, and ring system 50000 Quaoar is a dwarf planet in the Kuiper belt that measures approximately 1,110 km in diameter, or about half the size of Pluto. It hosts a single moon named Weywot and two narrow rings which both orbit outside of Quaoar's Roche limit. The outer...

2022 Nov 21: DART Mission + Didymos & Dimorphos 65803 Didymos and its moon Dimorphos are the asteroid targets of NASA's Double Asteroid Redirection Test (DART), which impacted Dimorphos in 2022 and ultimately shortened the moon's orbital period by 32 minutes. This impact ejected tons of dust, e...

Here's plume.dds and Explosion.cmod:

It's worth noting that Dimorphos's SPICE trajectory does not yet include its orbit change after the impact.

The inaccuracies in the orbits and rotations of Didymos and Dimorphos bother me a lot... may I lend you some assistance? :hi: Here is my update to the Didymos-Dimorphos system to JVV's DART addon. Do note that this does not change DART's trajectory, so the spacecraft ends up disappearing at an incor...

The 47171 Lempo system addon has been updated for corrections. *** CHANGE LOG *** * Used assumed triaxial dimensions from Correia et al. (2018) * Corrected semi-major axes of Lempo and Hiisi; both should have similar separation distances from their barycenter. * Added darkasteroid.dds for those who ...

Here's a whole album of pictures, so prepare uranus

Kiviuq.png Saturn's irregular moon Kiviuq as a elongated contact binary based on its large lightcurve amplitude in photometry by the Cassini spacecraft. The contact binary nature of Kiviuq is just merely a speculation; however, it is most likely elongated in shape. Source: https://www.hou.usra.edu/...
