What is the maximum number of eclipses that can occur each month?

Answer 1

Frequency of a Full MoonOnce every month.roughly. it actuly takes 27 days for the moon to travel around the earth but because the moon is traveling around the sun the moon has to catch up. so there is a full moon aproximatly 12.37 times a year.

One every 29.531 days.

Answer 2

Approximately 13.4 times per year. This is based on the moon's sidereal orbital period of 27.32 days. The sidereal orbit is the orbit around earth as it is observed from the distant stars, and independent of the moon's apparent movement as observed from earth. The synodic period of revolution is 29.53 days, and this is how long it takes for the moon to go through one full cycle of moon phases as observed from earth. There are roughly 12.4 lunar cycles per year. Because the earth is orbiting the sun at the same time that the moon is orbiting the earth, the moon has to revolve a little extra (beyond a full sidereal orbit) in order to get to the same phase as observed from earth as when the cycle began. In other words, the moon has to "catch up" with the earth in a sense. This is why the synodic period is a little longer than the sidereal period.

Rotations occur about an axis, while revolutions occur when one astronomical body orbits around another.

Every 29.5 days, for the past, oh, 3 billion years or so. We don't know precisely when the Moon came into being, but 3 billion years is a conservative estimate.

Answer 3

Solar eclipses generally occur about twice a year, depending on the exact alignment of the Sun, the Earth and the Moon. Sometimes the alignment isn't quite right and we see two partial eclipses a month apart instead of one total eclipse. But on average, there is a solar eclipse about every 6 months.

However, solar eclipses occur when the shadow of the Moon falls on the Earth. Because the Moon is so much smaller than the Earth, the shadow of the Moon is also smaller, and covers a fairly small area. So the same spot on Earth will only see a solar eclipse every few centuries or so. The next solar eclipse may only be 6 months later - but it will fall on a different part of the Earth.

Answer 4

Total solar eclipses happen every 1.5 years or so, but in any one calendar year there are between zero and five partial, annular, and/or total ones.

Typically, we expect two lunar eclipses and two solar eclipses each year. Next year, 2011, is one of the rare years with no solar eclipses at all.

You can look up the complete catalog of eclipses from 2000 BCE to 3000 AD on the NASA Eclipse Web Page at the link below.

Answer 5

The moon completes a cycle of phases every 29.53 days, so there are 12.37

complete sets of phases in 365.25 days.

Depending on when the first Full Moon is, there are either 12 or 13 total in

that year.

There are always 12. And if the first one occurs by January 10, then there's

enough time after it for 12 more by the end of the year.

And there's another, more elegant way to look at it: All of the moon's phases

are seen 12 times every year. And all of those phases that occur during the

first 10 days of January are seen one extra time that same year.

Answer 6

There are generally two solar eclipses and two lunar eclipses each year. Sometimes, we get two partial eclipses a month apart in place of one total eclipse. For example, in 2011 there will be four partial solar eclipses, and no total eclipses.

The maximum possible number of eclipses is five in a year, which is very rare.

You can take a look at NASA's Eclipse Page to see a catalog of all eclipses from 2000 BCE to 3000 AD.

The next eclipse will be a total lunar eclipse visible anywhere in North America on December 21, 2010.

Answer 7

See the related link, below, for a list of the dates for 2010.

One year of time ... 365.24 days ... is 12.37 times the period that elapses between

consecutive full moons. So, depending on the date of the January Full Moon, there

will be either 12 or 13 of them in the calendar year.

If there's a full moon on any of the first 10 days of January, then there's time for

12 more in that same year.

Answer 8

The moon revolves around the Earth, which in turn revolves around the Sun. So, the time taken for the Moon to complete one round around the Sun is the same as the Earth. That is 365 days. To answer your question, I must say that the moon revolves around the Sun 1/365 times a day.

Answer 9

Well, a solar eclipse can only occur at New Moon, and a lunar one only at Full Moon.

So, during one complete cycle of moon phases ... 29.53 days ... the maximum possible

is one eclipse of each flavor, for a grand total of two max.

Answer 10

In 365.25 days, there are 12.368 complete cycles of moon phases.

So there will always be 12 New Moons in a calendar year, and if the first one

occurs in the first 11 days of January, then there will be 13 that year.

The moon takes 27.32 days to orbit the earth, but a complete cycle of

the moon's 'phases' takes 29.53 days.
