Double or Full beds are 15 wider than a Twin, but if two share the bed, each has only 27 of personal space -- much less than a twin! A Queen bed is 6 wider than a Double bed, allowing more room for each person, but still 9 less than a twin bed.
The two points at which the Moon's orbit crosses the Earth's orbital plane are called the nodes of the Moon's orbit. So another way to state the conditions for a lunar eclipse is that (1) it must be full moon, and (2) the Moon must be at or quite near one of the nodes of its orbit. î î î.
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in  syzygy ) exactly, or very closely so, with the Earth in the middle.ence, a lunar eclipse can occur only the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes. A total lunar eclipse has the direct sunlight completely blocked by the earth's shadow.
