[SPACE] Tidal braking

[Agemegos]

No, dammit, that's not right. The unit for tidal range/amplitude in Space is the lunar tide on Earth, not the total tide. So the figure for lunar tide has to work out to 1.

Now let's see. Earth's diameter and density are both 1 by definition. The mass of the Moon is 0.0123, and the radius of its orbit is 30.16 Earth diameters. So

T = x * (M * D)/(rho * R^3)

1 = x * (0.0123 * 1)/(1 * 30.16^3)

x = 30.16^3 / 0.0123

= 2.23 million.

T (lunar) = 2.23 million * (M * D)/(rho * R^3)

All the variables are 1 by definition in the Solar tide on Earth, but since the tidal range unit is the Lunar tide not the total tide the coefficient ought to be 0.38, not 0.3.
