On Jan 26, 2009 there will be an Annular Solar Eclipse. This eclipse will be seen in South Africa, Antarctica, South East Asia, and Australia. On Feb 9, 2009 there will be a Penumbral Lunar Eclipse. This eclipse will be seen in East Europe, Pacific Ocean, and the Americas. On Jul 7, 2009 there will be a Penumbral Lunar Eclipse. This eclipse will be seen in Australia, Pacific Ocean, and the Americas. On Jul 22, 2009 there will be a Total Solar Eclipse. This eclipse will be seen in East Asia, Pacific Ocean, and Hawaii. On Aug 6, 2009 there will be a Penumbral Lunar Eclipse. This eclipse will be seen in West Asia, Europe, Africa, and the Americas. On Dec 31, 2009 there will be a Partial Lunar Eclipse. This eclipse will be seen in Africa, Australia, Europe, and Asia. I give most the credit to nasa.gov. My information was from that website.
Sooner or later, a lunar eclipse is seen by everybody on earth's "surface".
It could be seen by millions of people
Lunar eclipses and solar eclipses happen EQUALLY often; about two of each kind per year. However, solar eclipses are visible only across a small path on the Earth, while lunar eclipses are visible from the entire nighttime hemisphere of the planet.
About two per year, since the Moon formed. So, around 4000 solar eclipses (and 4000 lunar eclipses) since the year 1. You can check the list of all eclipses since the year 2000 BC on the NASA Eclipse Web Page at the link below.
You need to look up the dates of the next eclipses in your location and then be ready to look out for them. Eclipses of the moon are more frequent at any one place, because every eclipse is seen from the whole dark hemisphere of the Earth. Solar eclipses on the other hand are seen from a much smaller area because the Moon is much smaller than the Earth.
There are normally two solar eclipses each year. However, due to a curious alignment of the Earth, Moon and Sun, there will not be ANY solar eclipses in 2011!
Actually solar eclipses are slightly more common, but a solar eclipse, and especially the total phase, can only be seen in a relatively narrow strip of Earth.
On earth there are 2 eclipses, Lunar and Solar eclipses
Planets with moons may indeed have Earth-like eclipses. Eclipses happen when moon orbital plane intersects with planet orbital plane with respect to its star. Eclipses can only happen however if angular diameter of the moon is similar to (or greater than) angular diameter of star as seen from planet's surface, which is quite a rare condition. In the whole Solar System moon-eclipses only happen on Earth.
In the very distant past, the Moon's orbit was closer to Earth than it is now, and the Moon continues to VERY SLOWLY recede in its orbit. So it is likely (although I have not seen any calculations to bear this out) that in the distant past there would have been fewer annular eclipses and more total eclipses. However, there was nobody around to notice.
On average there are as many solar eclipses as there are lunar ones. But each lunar eclipse can be seen from half the Earth, while a solar eclipse can only be seen from a relatively small strip of the Earth's surface. So in any one place it seems that solar eclipses are rare.
Actually, globally solar eclipses are about as common as lunar eclipses, perhaps even a bit more common. However, they can only be seen from a narrow strip of Earth - especially if you want to see it as a total eclipse, while a lunar eclipse can be seen from half the Earth, more or less.
