In simple terms - its the orbit of the moon bringing it closest to the earth during the new moon phase. This means the moon's disc appears considerably larger than 'normal'
super moon normally occur at intervals of 20 years.
Its just a full moon during the period of the closest approach of the moon to the Earth.
As a matter of fact, that's exactly when it doesoccur.
Solar eclipses only happen on New moons when the moon is exactly in orbit between the Sun and the Earth.
They occur about once a year. Called perigee-syzygy or perigee moons by the astronomical community, they occur when a full or new moon (syzygy) is closest in its orbit to the earth (perigee), when the sun, earth and moon are aligned.
It must occur at new moon when the moon passes exactly in fron of the sun as seen from a place on earth. Usually at new moon the moon is not exactly in line and it passes above or below the sun so there is no eclipse.
Exactly the opposite. An eclipse of the moon, whether partial,total, or any other kind, can only happen at FullMoon.
Solar eclipses always occur at the new moon because the sun, moon and earth are in alignment. However because the orbits of the earth and moon are not exactly aligned with each other there are new moons when the sun appears to be above or below the new moon as seen from the earth.
A solar eclipse can occur only at the time of New Moon. A lunar eclipse can occur only at the time of Full Moon.
It is a combination of:* A super moon * A blue moon * And a blood moon
The Sun shines on the Earth and Moon, and each cast a shadow straight out into space. When the Moon goes into the Earth's shadow - when the Sun, Earth and Moon are lined up exactly - we have a lunar eclipse.
The "new moon" is when the Moon passes (almost) between the Sun and the Earth. The next new moon will be on November 16, 2009.If the Moon were to pass EXACTLY between the Sun and the Earth, there would be a solar eclipse.
