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.
In any case, the alignment must be close to perfect to cause an eclipse. An eclipse can only occur when the Moon is close to the plane of the orbit of the Earth, i.e. when its ecliptic latitude is small. This happens when the Moon is near one of the two nodes of its orbit on the ecliptic at the time of the syzygy.
