Why can't the moon be eclipsed when it is halfway between the nodes of it's orbit? It can't be eclipsed because most full moons pass too far north or too far south of the ecliptic and miss Earth's shadow.
When you see the moon its lit by the sun when you can't see all the moon its because the Earth is in the way and stopping light getting to that part of the moon so when the Earth is blocking sunlight from hitting any part of the moon you cannot see the moon at all because none of the surface of the moon is lit up by the sun.
A lunar eclipse can ONLY happen at a full moon; but if it's noon where you are, the Moon (and the lunar eclipse!) is on the other side of the world from you. So you won't see it.

Full Moon.
Eclipses would happen twice a month if the moon's orbit were in the same plane as the Earth's orbit around the sun. The moon's orbit is slightly tilted, so eclipses are less frequent. The plane of the moon´s orbit is inclined 5 degrees to the plane of the earth´s orbit around the sun. this being the case the moon´s orbit interesects the plane of the ecliptic at two different points (nodes). when one of these nodes is lined up with the sun and the moon passes through one of these nodes there is a solar eclipse. if the moon is at it´s apogee when this happens we have what´s called an annular eclipse because the moon´s disc does not completely block out the disc of the sun. when the moon is at there is a total eclipse.
The two points where the moon crosses the plane of the earth's orbit are known as the 'nodes' of the moon's orbit. If the moon happens to be near one of the nodes at the time of New Moon or Full Moon, then that's exactly when either a solar or a lunar eclipse can occur (respectively).
Pretty much, yes. You have the spring (vernal) and autumn (autumnal) equinoxes, so it's around that time. Midsummer's day is around the first day of summer. But the equinoxes aren't precisely (to the smallest fraction of a second) halfway between, because the velocity of earth's orbit is constantly changing throughout the year.
A "node" is a point where the Moon passes through the ecliptic plane (Earth's orbit around the sun). Because the moon's orbital plane around the Earth is inclined 5 degrees with respect to Earth's orbit around the sun, the Moon's orbit only intersects the Earth's solar orbit every 6 months (approximately). Solar eclipses occur when the Moon touches a node on the line of nodes between the Earth and the Sun. A lunar eclipse occurs when the opposite happens - the moon touches the ecliptic plane when the Earth is between it and the sun.

At the ecliptic (the plane of Earth's orbit around the Sun).
The lunar nodes are the orbital nodes of the Moon, that is, the points where the orbit of the Moon crosses the ecliptic. The ascending node is where the moon crosses to the north of the ecliptic. The descending node is where it crosses to the south.

Mercury and Venus orbit between the Sun and Earth.
shell and orbit are same
The planets that orbit between the Earth and the Sun are Mercury and Venus.
