'C' (the missing one) is the correct choice.
every 6 months For a lunar eclipse. solar eclipse take a lot longer.
In general, at least two to five solar eclipses happen every year. However, annular eclipses rarely happen. The latest annular solar eclipse happened in April 29, 2014.
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.
On average, every city WILL experience a LUNAR eclipse each year. About half of these will be partial eclipses.Solar eclipses are just as common - about two per year. But the area of totality for a solar eclipse is quite small compared to the area of the Earth, and the eclipses never occur in the same places twice in a row.
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.
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.
There are generally two solar eclipses and two lunar eclipses each year. Of the lunar eclipses, about 40% are "total"; the remainder are partial or penumbral. A lunar eclipse is visible from one-half of the Earth's surface. So on average, and weather permitting, you will see a total lunar eclipse about every third year.
Yes. There are 1 to 3 solar eclipses ... and the same number of lunar ones ... on the average every year.
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.
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.
No, eclipses can occur only at a new or full moon.
