I have some remarks about the orbital object data displayed in the tracking center. Please check my statements and please cut me down ruthlessly if I am wrong
Eccentricity should have no unit - it is a unitless measure. Currently it shows "°" (as in degrees angle)
Sidereal period is a time value and should be in seconds (or a derived unit). It now shows as m/s (as in speed)
Circumference (in the Physical block) I would expect to give me the circumference of the planet itself.
I have no idea what that value represents, but definitely not the circumference of the body (2 x PI x Radius of the planet). I approximated the orbital circumference, but that does not fit either.
The values for planet gravity have a unit as if they are absolute values, but when I calculate based on mass and density the values for all objects seem to be off by a factor of approx. 9.80 or the earth surface gravity (g).
Either use absolute values (Kerbin about 9.8 m/s^2 and Laythe about 7.84 m/s^2) or use relative values: the presented numbers but with a unit g (small letter to avoid confusion with G for Gravitational constant)
Just my 2 cents to help improve the work already done.
