Third Quarter Moon – After three-fourths of the Moon’s cycle, it is at its Last Quarter phase. It is now perpendicular to the Sun and Earth, but on the other side as the First Quarter Moon. Again, the Sun only illuminates about half of the Moon’s surface as viewed from the Earth. The Moon now READ MORE

Perigee – Based on the Greek word for the Earth (Gi), perigee is the position in an object’s orbit where it is the closest to the Earth. Typically, it is used for the Moon and other satellites.

New Moon – The Moon is in its New Moon Phase at the beginning and end of its lunar cycle. During the New Moon, the Sun’s light is illuminating the side the Moon that cannot be seen from Earth. The Moon is located between the Sun and the Earth is invisible to people there. The READ MORE

First Quarter Moon – After the first one-fourth of the length of the Moon’s cycle, it is at its First Quarter phase. It resides at a perpendicular plane in reference to the Sun and Earth, so the Sun only illuminates about half of the Moon’s surface as viewed from the Earth. The Moon now rises READ MORE

Apogee – Based on the Greek word for the Earth (Gi), apogee is the position in an object’s orbit where it is the farthest away from the Earth. Typically, it is used for the Moon and other satellites.

Ascending Node – An orbital node is the intersection of the celestial ecliptic and the orbital plane of a astronomical body. During an Ascending Node, the orbital body is crossing from the southern to the northern hemisphere of the celestial sphere. This gives the appearance of the object ascending. Eclipses can only occur when the READ MORE

Full Moon – The Moon is called Full when the side facing the Earth is completely illuminated by the Sun. This occurs halfway through the lunar cycle when the Moon is on the opposite side of the Sun as viewed from Earth. During this time, the Moon generally rises at dusk and sets at dawn, READ MORE

Perigee – Based on the Greek word for the Earth (Gi), perigee is the position in an object’s orbit where it is the closest to the Earth. Typically, it is used for the Moon and other satellites.

Third Quarter Moon – After three-fourths of the Moon’s cycle, it is at its Last Quarter phase. It is now perpendicular to the Sun and Earth, but on the other side as the First Quarter Moon. Again, the Sun only illuminates about half of the Moon’s surface as viewed from the Earth. The Moon now READ MORE
