But so to would Artemis 2.
In the reference frame of the Solar system's barycentre, Ted and #Artemis2, whilst not co-moving, have similar paths now that they are both on Terra.
We'd need to pick a reference frame closer to home, where Artemis 2 is now stationary and Ted continues to move. WGS-84 is the obvious choice, I think. I suspect Ted is already being measured in it.
I *definitely* wouldn't pick one with a billionaire as the origin point. The billionaire hopping onto a private (or even public) jet would make it seem like Artemis 2 was moving once again. Aside from complicating what is already a non-inertial frame, this seems like cheating to keep raising Artemis 2's total. (-:
Artemis 2 does get legitimate credit for a few thousand extra km, though, because the service module took its own path around the globe after separation from the crew module.

La fourmi, ce GPS vivant qui nous donne une leçon d'humilité
Pas de smartphone, pas de satellite, et pourtant la fourmi ne se perd jamais.
Pendant que nous cherchons désespérément notre chemin en fixant notre smartphone... elles lisent le ciel, suivent des pistes chimiques invisibles et comptent leurs pas comme une calculatrice vivante.
Leur secret ?
Un cocktail fascinant de phéromones, de lumière polarisée et d'intelligence collective. Le tout logé dans un cerveau grand comme un grain de poussière.
Et si le véritable paradoxe, c'était nous, l'être humain ?
Armés de milliards de neurones et des meilleures technologies du monde... pour mieux tourner en rond.

Today I learned that police can use GM's OnStar to remotely control a vehicle they are tracking.
From the Ontario Special Investigations Unit (SIU) report on shooting a man chased in a 2 day manhunt in Temagami in Oct 2025: "OPP communications coordinated with OnStar to track a pick-up truck, receiving intermittent GPS updates indicating the vehicle was moving and later stationary near Highway 11. OPP crews attended and set up a containment site at Roosevelt Road and Highway 11. The Complainant’s vehicle was sighted approaching the containment and then reversing away. Authorization was provided to OnStar to initiate a gradual slowdown of his vehicle."
The SIU report (case #25-PFI-401):

Many articles online about how US CBP/ICE and FBI have been making use of this.
