"Blood Moon" lunar eclipse

Very nice. Of course here in New England we had pretty solid cloud cover, so............. maybe next time.
 
There are three more going to happen in the next 17 months.

Gravitational Force between the earth and the moon?

F = G mM / r^2, where
F = gravitational force between the earth and the moon,
G = Universal gravitational constant = 6.67 x 10^(-11) Nm^2/(kg)^2,
m = mass of the moon = 7.36 × 10^(22) kg
M = mass of the earth = 5.9742 × 10^(24) and
r = distance between the earth and the moon = 384,402 km

F
= 6.67 x 10^(-11) * (7.36 × 10^(22) * 5.9742 × 10^(24) / (384,402 )^2
= 1.985 x 10^(26) N

Now I got to start all over, forgot to figure in the blood moon effect! Great Pics.
