lunar revolution?

Question

1. why do we not have 2 eclipses during one lunar evolution?


2. Which way does the moon revolve? and HOW does the moon revolve..like..wut does the moon do?

Answer 1

If the Moon's orbit around the earth were in exactly the same plane as the Earth's orbit around the Sun -- then we WOULD get two eclipses every month.

But in fact, the Moon's orbit is tilted by 5° from the plane of the Earth's orbit. That means that most of the time, when the Moon is new, it misses the position of the sun, and when full, most of the time the Moon misses Earth's shadow -- and no eclipse occurs.

But there are two times a year when the "nodes" (the places in the sky where the two orbits intersect) are aligned right, and eclipses can occur. Because these nodes move from year to year, the "eclipse seasons" shift from year to year too.

The moon revolves around its axis, like the Earth does, but because the Moon is in tidal lock with the Earth, one face of the Moon always points in Earth's direction. That means that it takes 29.5 days, on average, for the Moon to complete one revolution -- the same time as it is from one full Moon to the next.

Answer 2

The moon does what it was designed for . It is meant to be a mirror reflecting sun light at night so we would not be completely in the dark.
The moon trace a clover leaf path during a period of 18.5 years.
The motion of the moon as observed from a fixed star is a cyclodal path relative to the Sun.

The motion of the moon relative to the earth traces an elipsoical path.The moon spin takes 27.3 side real days. For that reaon we see the same face of the moon during its month period.

Answer 3

moon just rotate around the earth, thats all it does.
The earth and the moon rotate around the sun. It is the relative location of the earth to the sun and moon that produces the eclipses.
