'C' (the missing one) is the correct choice.
every 6 months For a lunar eclipse. solar eclipse take a lot longer.
No, annular eclipses do not happen every year. They occur when the Moon is farthest from Earth, making it appear smaller and not fully cover the Sun during the eclipse. This alignment is not a regular occurrence, so annular eclipses happen less frequently than total solar eclipses.
Yes, there were several eclipses in 2012. There was a total solar eclipse on November 13, 2012, and a lunar eclipse on November 28, 2012.
On average, there are about 2-4 lunar eclipses each year. These can vary in type, with some being total eclipses and others being partial or penumbral eclipses.
Lunar eclipses happen about twice a year at the full moon. Solar eclipses happen about twice a year at the new moon.The link below to the NASA Eclipse Site lists details about every eclipse from 2000 BC to 3000 AD.
Every year there are at least two lunar eclipses, although total lunar eclipses are significantly less common.There was a total eclipse of the Moon on December 21, 2010The next total eclipse of the Moon will occur on June 15, 2011.
We see solar eclipses only during New Moon, but not every New Moon is accompanied by a solar eclipse.
Yes. There are 1 to 3 solar eclipses ... and the same number of lunar ones ... on the average every year.
There are generally two solar eclipses and two lunar eclipses every year. You can see a list of all the eclipses from 2000 BC to 3000 AD on the NASA Eclipse Web Site at http://eclipse.gsfc.nasa.gov/eclipse.html. The next total solar eclipse will be on July 22, 2009. It will be visible in northern India and China, and across the Pacific Ocean.
Generally, a lunar eclipse happens _about_ every 6 months - or, to be more precise, every 6 full moons, which isn't exactly the same thing. Sometimes there are two partial lunar eclipses a month apart rather than one total lunar eclipse, but on average, every 6 months or so. You can see the catalog of all eclipses from 2000 BCE to 3000 AD on the NASA Eclipse Web Site at the link below.
Globally, solar eclipses are slightly more frequent. But a lunar eclipse can be seen from any place where the Moon is above the horizon, whereas a solar eclipse can only be seen from a narrow strip of land. So, for any particular fixed observer, solar eclipses - and especially total solar eclipses - are quite rare. During the 100 years of the 20th Century, there were 228 solar eclipses and 229 lunar ones. So over the long term, you can figure on equal numbers, at the rate of around 7 of each every 3 years.
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.
