Okay, predicting eclipses without google 101.
Moon period is 27.3 days (.0748 years)(I used Google for this, but I didn't want to wait a month to do it myself.)
Using Kepler's third law, the semi-major axis is going to be (.07482/3)= .00257AU
moon's average distance= .00257AU
Sun's average distance= 1AU
moon is around 390 times closer than the sun.
moon's angular diameter= 31arcmin
sun's angular diameter= 30 arcmin
The moon should be completely eclipsed around around 40% of the time that it is annularly eclipsed (Kepler's second law)
lunar inclination is such that it only has two chances per earth year of eclipsing each orbit, and around 40% of those will be total.
so on average, around .8 total eclipses per earth year.
I haven't used google, so can anybody tell me how close I got?
