They never do. They're always at least a month apart,
and far more often several months apart.
Actually it doesn't. Typically, a lunar eclipse happens about twice a year.
TWICE.
It happens every month, but that does not mean in the same place. Lunar eclipses happen twice a year in a 1-2 month period.
The full moon cycles through each of the zodiac signs 12 times a year. Occasionally, it will occur in the same sign twice in one month.
Because the moon does not orbit in the same plane as the Earth-Sol plane. Note that they will only form a straight line twice per year, and if the three bodies are not lined up there will be no eclipse.
Lunar eclipses can happen a maximum of twice per year, and only at the time of the full moon. Sometimes the alignment is just right, and we get a total lunar eclipse. If the alignment isn't exact, we might get a partial or a penumbral eclipse instead of a total eclipse.
No. Two of them can't occur closer together than a few months.
Lunar Eclipses happen on average twice a year.
The moon crosses the equator twice each lunar month due to the moon's change of declination.
About twice a year.
Solar eclipses happen twice a year or so. The problem is that the geometry is a little touchy; if it isn't just so, you won't get a total eclipse, but only a partial eclipse. And the area of the Earth affected by the solar eclipse is very small; a path about 100 miles wide and a few thousand miles long. Since 75% of the Earth's surface is water, a lot of eclipses aren't visible on land at all. NASA's Eclipse web page will let you see when each eclipse will occur, and where.
If you're referring to complete lunar eclipses (a lunar eclipse when the moon is full) then unlikely....but any other lunar eclipse (any other moon phase) usually happens atleast twice a year.
