I wonder what tech we have that can measure something that slow? Wouldn’t it just look stationary?

[–] Canuck1701@lemmy.ca 2 points 1 year ago

It does basically look stationary, but if you know the masses of the planet and the star and know the radius of orbit, then you can determine what the speed must be for it to be a stable orbit.

Very accurate tech :)
