What do you call a lunar eclipse when the moon is not big enough to cover the whole sun?

The Moon is in an elliptical (or oval-shaped) orbit. When a solar eclipse occurs near apogee, when the Moon is farthest away from the Earth, the apparent size of the Moon is smaller than the apparent size of the Sun. So we get an "annular" eclipse.

How is a total lunar eclipse different from other lunar eclipse?
A full lunar eclipse covers the whole sun while others only partially cover the sun
What is the difference between the lunar eclipse and solor eclipse?
In a lunar eclipse the Earth is in the middle and blocks the Sun's light from the Moon, so that happens always at Full Moon but not every time. A solar eclipse has the Moon in the middle so it happens at New Moon, but not every time, and the Moon is not big enough to shadow the whole Earth so a solar eclipse is seen only in a strip across the Earth's surface.
Why is totality during lunar eclipse not altogether dark?
Earth's atmosphere refracts some light, mostly red light, into its shadow. This light falls on the moon's surface during a lunar eclipse, turning it red. If Earth did not have an atmosphere, the moon would go completely dark during a lunar eclipse.
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.
Why more people see a lunar eclipse?
I believe it is because of the technology we have this day and age. It's because a lunar eclipse can be seen from half the Earth, while a solar eclipse only occurs along a relatively narrow track on the Earth's surface. The Moon is too small to eclipse the whole Earth all at once, so although there are as many solar eclipses as lunar, fewer people get to see each one.
Do the highlands cover a lot of the moon?
Yes, 83 per cent of the whole lunar surface (including the far side) is covered by lunar highlands.

When do lunar eclipses occur?
Lunar eclipses occur when the moon passes into the Earths shadow. So just as a solar eclipse occurs when you get the Sun, moon and Earth lined up (in that order), a lunar eclipse occurs when you get them lined up in the order Sun, Earth, moon.When the earth sun and moon comes in a straight line earth in the middle the lunar eclipse occurs.A lunar eclipse can only happen during a FULL MOON.It can only occur when the earth moon and sun are all lined up, with the earths shadow being cast on the moon (earth between the sun and moon). Even then it's not guaranteed, as the alignment has to be perfect. The orbits at not perfect circles and on the same plane so this is quite rare. A lunar eclipse will happen with a new moon.It occurs when the Earth is directly between the Sun and Moon. It must be a full moon when it happens. To see a full lunar eclipse, ou must be in the umbra. If you're in the penumbra, you wouldn't see the whole eclipse but most of it. ~ha.
Why do you have solar or lunar eclipses?
When the moon comes in between earth and the sun we witness solar eclipse. Though much smaller than the sun, the moon is much closer to earth so, it can cover the whole sun (from our view). The moon has no light of its own. It only reflects the light it gets from the sun. But, when earth comes in between the sun and the moon the shadow (umbra) of earth covers the moon completely. That's what we call lunar eclipse.
Why does the the Moon remain partly visible during a lunar eclipse?
The moon remains partly visible during a lunar eclipse because light is refracted round the earth by its atmosphere. A lunar eclipse is when the moon passes through earths shadow. A partial eclipse,is when only part of the moon is in earths shadow.Then the moon might look like something took a bite out of it.Unlike a partial eclipse,a total luna eclipse occurs whe the whole moon is in the earths shadow.The moon does not disappear during a lunar eclipse.Earths atmosphere bends and scatters some sunlight,allowing some of the suns rays to reach the moon.Lunar eclipses happen several times a year.
Why is lunar eclipse a fairly common phenomenon as compared to the solar eclipse?
Both types of eclipse occur in virtually identical numbers, averaging about 2.4 ofeach type per year over a long period of time. (The 20th Century had 238 solarand 239 lunar eclipses.)But ... a solar eclipse, when it happens, is visible from only a small part of theEarth's surface, whereas a lunar one, when it happens, is visible from anywhereon the whole night half of the Earth. So from any one place on Earth, lunar eclipsesare visible more often than solar ones.
When can you see a total solar eclipse?
A solar eclipse happens at New Moon when the Moon passes in front of the Sun. The Moon is not big enough to eclipse the whole of the Earth so the eclipse is seen only over a strip of the Earth's surface. The Moon's orbit is inclined to that of the Earth, and usually at New Moon the Moon passes above or below the Sun as seen from the Earth. When the Moon is at a node, that means that it is crossing the plane of the Earth's orbit, an eclipse can occur if that coincides with New Moon, because then all three are all in a line. The same applied to lunar eclipses at Full Moon, except that a lunar eclipse can be seen from the whole dark side of the Earth. This makes lunar eclipses seem more frequent. A solar eclipse on the Earth, seen from the Moon, looks like a circular area of shadow on the Earth's surface with a tiny black dot at the centre, which is the point of total eclipse, a moving circle of about 20-40 miles across. Anyone in that dot is seeing a total eclipse.
