"You're a Southern Keplerian, right?"

"Aww, don't say that! I punch blokes in the mouth for saying that! That's really hurtful. My family has been on Earth for 300 years!"

I'm calling him KEPLATTER. 😂😝

Just thought I'd share a small but personally significant milestone in my recovery. I've been getting back into my art, now that I'm back home and can sit up more comfortably for longer periods of time. It's easier to draw, especially not being hooked up to IVs and machines. I hope to introduce to you more aliens, sorry Terrans (don't want Keplatter to punch me in the mouth), as I go. 😊♥️

🪐 First direct #imaging of a forming #exoplanet carving multiple rings in its accretion disk! Van Capelleveen et al. (2025) reveal a ~5 MJup #protoplanet 57 AU (~8.5 billion km, farther than Pluto) from its star (#WISPIT2, ~133 pc) with #VLT/SPHERE, showing #Keplerian motion and Hα #accretion. A rare, striking view of planet–disk interaction in real time 💫

I am still in this rabbit hole, learning a bunch of new #numerical methods.

What I want at the end is *thrust* acceleration values recovered from satellite position and velocity data given at 1m intervals.

Any method will obviously also have the acc due to gravity and other effects. Methods will differ in how much numerical "noise" they add to the process.

Subtracting the Earth is easy with F=ma=GMm/r^2.

To compare the noise, I'm using a smooth #keplerian element set that has no thrusts.

<<Alternatively, a more exotic scenario is that Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization.>>

PS: the sad part is that if by chance it was an alien probe, she approached, saw us and left at full speed leaving us alone.
