On Sunday, 11 July 2010 , a Total Eclipse of the Sun is visible from within a narrow corridor that traverses Earth's southern Hemisphere. The path of the Moon's umbral shadow crosses the South Pacific Ocean where it makes no landfall except for Mangaia (Cook Islands) and Easter Island (Isla de Pascua). The path of totality ends just after reaching southern Chile and Argentina. The Moon's penumbral shadow produces a partial eclipse visible from a much larger region covering the South Pacific and southern South America.
As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially covers the Sun as viewed from some location on Earth. This can only happen during a new moon, when the Sun and Moon are in conjunction as seen from Earth. At least two, and up to five, solar eclipses occur each year; no more than two can be total eclipses.Total solar eclipses are nevertheless rare at any particular location because totality exists only along a narrow path traced by the Moon's umbra.
A total solar eclipse is a natural phenomenon. Nevertheless, in ancient times, and in some cultures today, solar eclipses have been attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of their astronomical explanation, as the Sun seems to disappear in the middle of the day and the sky darkens in a matter of minutes.
There are four types of solar eclipses:
1- A total eclipse occurs when the Sun is completely obscured by the Moon. The intensely bright disk of the Sun is replaced by the dark silhouette of the Moon, and the much fainter corona is visible. During any one eclipse, totality is visible only from at most a narrow track on the surface of the Earth.
2- An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the outline of the Moon.
3- A hybrid eclipse (also called annular/total eclipse) transitions between a total and annular eclipse. At some points on the surface of the Earth it is visible as a total eclipse, whereas at others it is annular. Hybrid eclipses are comparatively rare.
4- A partial eclipse occurs when the Sun and Moon are not exactly in line and the Moon only partially obscures the Sun. This phenomenon can usually be seen from a large part of the Earth outside of the track of an annular or total eclipse. However, some eclipses can only be seen as a partial eclipse, because the umbra never intersects the Earth's surface, passing above the Earth's polar regions.
The Sun's distance from the Earth is about 390 times the Moon's distance, and the Sun's diameter is about 400 times the Moon's diameter. Because these ratios are approximately the same, the Sun and the Moon as seen from Earth appear to be approximately the same size: about 0.5 degree of arc in angular measure.
The Moon's orbit around the Earth is an ellipse, as is the Earth's orbit around the Sun; the apparent sizes of the Sun and Moon therefore vary.The magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse. An eclipse when the Moon is near its closest distance from the Earth (i.e., near its perigee) can be a total eclipse because the Moon will appear to be large enough to cover completely the Sun's bright disk, or photosphere; a total eclipse has a magnitude greater than 1. Conversely, an eclipse when the Moon is near its farthest distance from the Earth (i.e., near its apogee) can only be an annular eclipse because the Moon will appear to be slightly smaller than the Sun; the magnitude of an annular eclipse is less than 1. Slightly more solar eclipses are annular than total because, on average, the Moon lies too far from Earth to cover the Sun completely. A hybrid eclipse occurs when the magnitude of an eclipse transitions during the event from smaller than one to larger than one—or vice versa—so the eclipse appears to be total at some locations on Earth and annular at other locations. The Earth's orbit around the Sun is also elliptical, so the Earth's distance from the Sun varies throughout the year. This also affects the apparent sizes of the Sun and Moon, but not so much as the Moon's varying distance from the Earth. When the Earth approaches its farthest distance from the Sun (the aphelion) in July, this tends to favor a total eclipse. As the Earth approaches its closest distance from the Sun (the perihelion) in January, this tends to favor an annular eclipse.

Wow... nice video. I've always wanted to know..during a solar eclipse when the sky goes dark for a while, can you spot stars/constellations that you would not normally see as it only appears during the day?

@thangacchi you welcome..glad you enjoyed the video and found it useful..
yes during Total Solar Eclipses the planets and bright stars can be seen clearly. its a magical moment that lives forever ...

wait...how can this be? the video was posted in June, but its supposed to be showing something that happened in July! I know its a simulation, but wouldnt they know what the real one had to look like before the made a "fake" one? O_o

@metakirbydedede3 I tell you this myself, take the word of fake out of your mind when comes to Eclipses predictions and simulaltions.. as Astronomers do know the next 100000 years of Eclipses for sure and we do calculate the Ancient ones too...the video you see here I uploaded in 13 June 2010 to let every body aware of the Total Solar Eclispe that was going to happen in 11 July 2010, and those who looked at my video and knew about it, prepared for it, send me messages of appreciations.

@metakirbydedede3 I have a Planetarium that lets me to know of any Astronomical Events ahead of our times for the next 99999 years..so don't be surprised to show you how the actual eclipses look like before the real ones...its what I do here making videos about Solar and Lunar Eclipses, Seasons, Asteroids and comets too,..for that people subsribe to my channel to be aware of any future events...you too can be learn abut them to if you choose to do so...thanx

Hey, any idiot can see that the water is not moving, so this is obviously a simulation. Calm yourselves down, it's nothing special.

@EzioCampbelli Its a Planetarium program generated by computer to let you and others around the world that Solar Eclipse happen on that day, so tens of thousands people around the world who had seen and knew there would be a Toatal Solar Eclipse on that day, they prepared for it and when they did, they show their excitement here and their apprecitations, but all of these peole knew that I uploaded this a month before the actual day, to give them enough time to prepare, of course except 4 you!
