The Sun is about a million miles across, while the Earth is only 8000 miles across and the Moon is only 2150 miles in diameter. Because the Sun is so much bigger than the Earth or the Moon, the shadows of the Earth and Moon are cone-shaped.

So the shadow of the small Moon gets even smaller by the time the shadow gets all the way to Earth, 240,000 miles away. In fact, the distance from the Sun to the Moon varies from 225,000 miles at the perigee to 252,000 miles at the apogee. When the Moon is in close, the diameter of the total part of the shadow - the "umbra" - is only about 300 miles. When the Moon is further away, the cone-shaped umbra of the Moon's shadow doesn't reach all the way to the Earth; that's when we have "annular" (ring-shaped) eclipses.

Where the umbra of the Moon's shadow touches the Earth, we have a "total" eclipse. Around that spot is a ring of "partial" eclipse where the Sun is peeking out from behind the Moon. Further away from the umbra, the Moon doesn't block the Sun at all.

Do the people in the umbra only see a partial solar eclipse?

NO they don't. First the Solar Eclipse is on the other side of Umbra. They don't git to see much of it.Because it is usually to dark to see the moon in Umbra.


When a solar eclipse happens who can see it?

A solar eclipse can be seen by people located within the path of totality, which is a narrow area where the moon completely blocks the sun. Those outside this path will experience a partial eclipse. Viewing a solar eclipse requires proper eye protection to avoid damage to the eyes.


Can everyone see the solar eclipse?

Definitely not! Two people standing right next to each other will generally have the same view, but if two people are a mile apart, its' possible that one will experience a total solar eclipse while the other will see only a partial eclipse. For people who are right on the edge of the path of totality, it's possible to do an interesting experiment; line up a set of telescopes every 10 yards or so, connected to photosensors and highly accurate clocks. Measure the precise time at which the Sun flickers into view through the valleys in the mountains on the Moon, and you can create amazingly accurate elevation maps of the lunar mountains.


Why do partial solar eclipses occur more than total solar eclipses?

There are 4 types of solar eclipse. Total, Hybrid, Annular and Partial eclipses.A Total Eclipse is when the sun totally covers the sun.An Annular Eclipse is when the whole moon is in line with the sun but the apparent diameter of the moon is less than the apparent diameter of the sun.A Hybrid Eclipse is when some places on Earth experience a annular eclipse and other places see a total eclipse.A Partial Eclipse is when the moon is not totally in line with the sun and only eclipses part of the sun.


A total solar eclipse can only be seen by people in the area of Earth within the Moon's umbra?

Short answer: True. Long answer: not entirely true as follows: The eclipse event as a whole is visible to anyone within either the umbra or the penumbra, however it appears as truly total only to those within the umbra. That is, those who are not in the umbra are seeing an event that will be called a "total eclipse", just not optimally, as it will appear only partial to them.

What do people in the penumbra see during an eclipse?

People in the penumbra during a solar eclipse will see a partial eclipse, where the sun is only partially covered by the moon. This results in a crescent shape of sunlight rather than a total blockage. The amount of sunlight that is blocked will depend on how close they are to the umbra, the central region of the shadow.

Who on earth's surface can observe the total solar eclipse when it occurs?

People located within the path of totality, which is the narrow area where the total solar eclipse can be seen, will be able to observe it. This path can vary for each eclipse and location. Those outside the path will only see a partial eclipse.

What happens if the moons shadow falls on the Earth?

In that case, a Solar Eclipse occurs. It can be a partial or total eclipse depending on the positions at the time of the eclipse. In total Solar Eclipses, the sun is completely blocked out for a short time in some parts of the world. Likewise, Earth's shadow falling on the Moon is known as a lunar eclipse.


When is a solar eclipse visible from any place on earth?

No single eclipse ... solar or lunar ... is ever visible from every place on earth.No single solar eclipse is ever visible from every place or even half of the earth.

Wise people get experience from others?

wise people don't get experience from others. It is a big generation brain power thing. ;1!


Do partial lunar eclipse occur more often than total eclipse?

Total solar eclipses are much less frequent because it is much more likely that part of a planet/moon/satellite gets partly in our way of the sun than a planet/moon/satellite gets 100% in our way.


Why are people in the umbra the only ones to expierence a total solar eclipse?

By definition, they are the only ones that cannot see any part of the Sun as the Moon passes in front of it. As opposed to "penumbra"... or partial solar eclipse.
