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.
occur because the plane of the moon's orbit crosses the plane of the sun's orbit (which is also called the ecliptic) at two points known as the nodes of the moon's orbit, the moon must be at one of the nodes and directly between the sun and the earth in order for a solar eclipse to occur (the moon phase is new), and it must be at the the other node and on the opposite side of the earth from the sun in order for a lunar eclipse to occur (the moon is full), I.E. the line connecting the nodes ...
