well this is something for my school project and I really need this information... I can´t seem to find it on internet.. so i just hope you guys help me with it...
I found some differences between lunar eclipses and solar eclipses.. (such as.. the lunar eclipses last longer than the solar ones...there´s no danger in looking at the lunar eclipse without protection unlike the solar one...ohh please tell me if im not right).. and some others..but what i really need right now are the similarities.. although.. if you guys can tell me any other differences.. I´d really appreciate it..
thnxx

One similarity: The "middle" body casts a shadow on the body furthest from the sun. In a lunar eclipse, Earth is the middle body; in a solar eclipse the Moon is the middle body.
Differences:
Yes you can look at a lunar eclipse without eye protection.
We see the shadow projected on the Moon in a lunar eclipse; we on Earth are in the shadow in a solar eclipse.
A lunar eclipse is visible anywhere you can see the moon (unless it's a very partial eclipse in which case parallax may prevent a viewer at one extreme of the lunar visibility region (either the moonrise or the moonset extreme) from seeing it. Similarly a total lunar eclipse is generally visible wherever you can see the moon, but with the same possible exception if it's just barely total.
A partial solar eclipse may just "graze" the Earth (and be visible only in the grazed region); a non-grazing solar eclipse has a partial-eclipse path about 2000 miles wide (thus being missed in many locations where the sun is visible) and a total eclipse is normally only visible over a quite narrow path where just the tip of the moon's umbra (total shadow) intercept's Earth's surface. The ref. also mentions a "hybrid" solar eclipse in which, due to the Earth's non-spherical shape, some regions will see a total eclipse while others, slightly further from the moon, will see the annulus of light that is the outer edge of the sun's light-radiating surface.
These differences bring up what is perhaps one of the most significant features of a total solar eclipse: the fact that the Moon and the Sun have, coincidentally, almost exactly equal angular width when viewed from Earth, which in the early history of astronomy enabled study of the Sun's edge or "limb", prominences and corona, and possibly advanced the science considerably beyond what it might have been without this coincidence.

the solar eclipse occurs when the moon passes between the earth and the sun.Since the moon and the sun appear to the same size in the sky,the moon can completely block the sun if the relative positions of the moon and the viewer are just right. The lunar eclipse occurs when the earth passes between the sun and moon.Since the earths shadow is larger than the moon,it can be completely blacked out.Actually a total lunar eclipse rarely blacks out the moon completely.

In both kinds of eclipses, three bodies are in a line: sun, moon, earth.
Lunar eclipse - we can't see the moon because the Earth is in the way and the sun's light can't bounce off the moon.
Sun - Earth - Moon
Solar eclipse - we can't see the sun because the moon is in the way and we lose our view of the sun for a little bit.
Sun - Moon - Earth

Well, they both happen when they are in alignment with the Earth and Sun. Also, they both have three different kinds (Solar=Total, Partial, and Annular while Lunar=Total, Partial, and Penumbral). Lastly, each one happens at least 2 times a year--Lunar happens just a little bit more than the Solar.

Both involve the Earth and shadows. If you cannot find information about eclipses you are not even trying a search!
