Mainly the distance between the Moon and Earth.
Annular solar eclipses occur when the moon is too far away from earth to completely cover the face of the sun, leaving a thin 'ring' of uncovered sun around the edge of the moon. This is different from a partial eclipse in which the moon does not align with the sun in such a way that the sun is completely blocked. Annular eclipses would occur only when the moon is at or near apogee, its farthest approach to earth. A+: when the moon is at apogee
ya..take a huge chunklet of cardboard n cut a square in the center then tape tin foil over it. p.s. it not a full solar eclipse c; so yuh might not need them..its only an annular one.good day mate.
Animals located near the center of a solar eclipse may think that night is coming,and may assume their sleeping positions temporarily.There is no evidence that a lunar eclipse has any effect at all on people or animals.
when the moon goes straight through the center of the Earth's shadow, or at least close enough to the center that there is some time when the moon is completely in it
Solar eclipse is when the Moon gets between the Sun and the Earth - the Moon's shadow falls on the Earth. If you stand in the center of the shadow it will look like the complete Sun is blocked out and things will get very dark - a total eclipse. If you stand on the edge or near to the edge of the shadow, only part of the Sun is blocked out and things just get a bit dull - a partial eclipse. Solar eclipses happen regularly every year and will be seen somewhere on Earth, maybe way out to sea.

an umbra is the center of the solar eclipse which is the darker part and the penumbra is farther away from the center of the eclipse and is brighter than the umbra

There will be an annular solar eclipse on January 15, 2010. It will be visible along a path from central Africa to the southern tip of India and the northern tip of Sri Lanka and across China.An annular eclipse is a "ring of fire" eclipse, when the Moon is so far away from the Earth that the Moon doesn't cover up the Sun completely, and the central "umbra" shadow doesn't reach the Earth at all. The wider partial eclipse will be visible for most of Africa, some of eastern Europe, India and Asia.
According to the following website:http://www.interfacebus.com/glossary-of-terms-minimum-annular-ring.htmlMinimum Annular RingThe minimum annular ring on a plated thur-hole is the minimum amount of copper (at the narrowest point) between the hole and the edge of the pad after plating of the finished hole. MIL-STD-275E and IPC class 3 calls for a minimum annular ring of 0.05mm (0.002") edge of hole to edge of pad. MIL-STD-275E also calls out .005 inches for via to trace distance. Minimum Annular Ring; PWB Internal ViaBoth diagrams indicate minimum annular ring measured from the outside ring of the pad and to the inside diameter of the plated thru-hole for an external pad [below], or to the center of the plated via for an internal pad [above].Minimum Annular Ring; PWB External PadMinimum Annular Ring applies regardless of the shape of the PCB pad. The next page shows two examples of different pad shapes.More Printed Wiring Board Terms

From Earth, we routinely experience two kinds of eclipses: an eclipse of the Moon and an eclipse of the Sun.Eclipses of the MoonSometimes, as the Earth orbits the Sun, it comes between the Sun and the Moon. When this happens, the Earth throws a dark shadow across the Moon. This is known as an eclipse of the Moon, or a lunar eclipse.Eclipses of the SunSometimes, the Moon passes between the Earth and the Sun. The Moon blocks the light of the Sun and a shadow of the Moon is cast on the Earth's surface. This is an eclipse of the Sun, or a solar eclipse. There are three types of a solar eclipse: total, partial, and annular. During a total eclipse, the Moon completely covers our view of the Sun. A total eclipse is only visible from a narrow strip (about 150 km wide) of the Earth's surface at any one time. From the areas outside this narrow strip, the Sun appears to be only partially covered and a partial eclipse is seen. A partial eclipse will also occur if the Sun, Moon, and Earth are not precisely lined up. The eclipse cannot be total unless the center of the Moon's shadow is able to strike the Earth. The eclipse type that occurs when the Moon is at its farthest distance from the Earth is an annular eclipse. The Moon then appears too small to completely block out the disk of the Sun.lol i know theres a lot but can u asnwer my question please if u can :)Actually I asked that question-this is the questioner-because people kept spelling it incorrectly and I wasn't sure if they were talking about eclipses or not and I'm still not sure if they mean Eclipses.Do you think they mean Eclipses???They better do cos i wasted my time lookin 4 tht cos im meant to be doing stuff 4 hwk wich im stuck on :S
