The earth's distance from the sun is not constant, but varies slightly. Naturally, when the earth is closer to the sun, the sun appears slightly larger, but the effect is so small that we never notice it. The moon's distance from the earth is not constant, but varies slightly. Naturally, when the moon is farther from the earth, it appears slightly smaller, but the effect is so small that we never notice it. When a 'central' solar eclipse happens to take place at a moment when the sun is closer than average AND the moon is farther than average, the sun looks bigger than average and the moon looks smaller than average. At that moment, their centers coincide and we would hope for a beautiful total solar eclipse. But the moon is not quite big enough to cover the full disk of the sun, so there is a narrow ring of unobstructed sun sticking out around the edge of the moon. Just to sound wise, astronomers call the ring an "annulus", and this event is called an "annular" eclipse.

∙ 14y agoThe Moon is in an elliptical orbit; some times it is closer to the Earth, and sometimes farther away. When there is a solar eclipse with the Moon close to Earth, we get a total eclipse. When the eclipse happens when the Moon is farther away, it appears smaller - too small to completely cover the Sun. which gives us an annular eclipse.

Is the ring nebula a cloud?
The Ring Nebula is classified as a planetary nebula which is a shell of gas and plasma, formed when certain stars die.So, in a way they are clouds of matter in space.
The word ''ring'' is an example of what type of figure of speech?
The word hiss is an example of onomatopoeia - when a word is formed from the sound of something.
How is umbra formed?
When the Earth experiences a total solar of lunar eclipse, the shadow of the moon falls on the Earth and on one particular spot. There you can see the total solar or lunar eclipse, but any other place you don't realize it.

What is the moon phase during an annular eclipse?
An ANNULAR Eclipse only occurs at a NEW MOON. An annular eclipse is a 'ring' of sunlight around the Black Lunar Disc.
What an annular eclipse?
An annular eclipse is a solar eclipse in which the thin outer disc of the sun can be seen as a ring around the moon.
When a thin solar ring is visible around the edge of the moon is what?
This is seen during an "annular eclipse".
What is a solar eclipse that leaves a ring around the sun?
An annular eclipse.
What is the ring around a full solar eclipse called?
This type of eclipse is called an "annular eclipse" and the ring is an "annulus".
What causes an annular eclipse?
An annular eclipse or annular solar eclipse is when the moon isn't close enough to the Earth during a solar eclipse to cover the whole circumference of the Sun, leaving a ring of light around the Moon.
When the earth enters into the moon shadows what is the name of the eclipse?
Solar eclipse, either Total, Partial or Annular aka Ring of Fire
What causes a solar eclipse to be annular?
The Moon's distance from the Earth can vary. This is because the Moon orbits the Earth in an ellipsoid manner, with the Earth at one of the foci. On this ellipsoid the Moon can be nearer to, or further away from the Earth. When all objects are further away from the observer, they appear to be smaller. Hence fir an annular eclipse the Moon is further away, therefore it appears smaller and allows a 'ring' of solar light around the black lunar disc. When the Moon is nearer the Earth you have a Total Solar Eclipse, where at best you only see the corona. NB the word 'foci' is the plural of the noun 'focus'. 'Focuses' is the verb. An ellipse has two foci. The Earth being at one of the foci, the other being a 'blind' foci. The word 'foci' is pronounced as 'foe-s-eye'. the 'c' is soft and pronounced like an 's'.
What does an annular eclipse look like?
it has a ring around it go to this site for more and look at the picture it shows http://sci.esa.int/science-e-media/img/c0/Mvc-680f-410.jpg
If the moon's umbra fails to reach Earth?
There are times that the umbra of the moon fails to reach the Earth. This is when the moon is at apogee. When this happens, observers witness an annular, or ring, eclipse. During anannular eclipse, observers in the umbra see a thin, bright ring around the moon.
A ring eclipse is?
Also known as Annular, it would be a total Solar eclipse if the Moon were nearer the Earth at the time (the Moon's orbit is not a perfect circle). The further the Moon is from the Earth, the smaller it appears and thus cannot completely cover the Sun.
When is the 2013 solar eclipse?
Solar Eclipses occur when the Moon passes between the Sun and the Earth and directly blocks the light of the Sun. Because the Moon is located between the Sun and Earth the dark side of the Moon is facing Earth and is in a New Moon Phase. An Annular Solar Eclipse is a solar eclipse in which the Moon's antumbral shadow traverses Earth (the Moon is too far from Earth to completely cover the Sun). During the maximum phase of an annular eclipse, the Sun appears as a blindingly bright ring surrounding the Moon. An annular eclipse will be visible in Australia, New Zealand, and the Central Pacific on May 10, 2013. A hybrid solar eclipse is a solar eclipse in which the Moon's umbral and antumbral shadows traverse Earth (the eclipse appears annular and total along different sections of its path). Hybrid eclipses are also known as annular-total eclipses. In most cases, hybrid eclipses begin as annular, transform into total, and then revert back to annular before the end of their track. In rare instances, a hybrid eclipse may begin as annular and end total, or vice versa. A hybrid eclipse will be visible in the Eastern Americas, Southern Europse, and Africa occur on November 3, 2012.
