Back burning sensations are any sensations anywhere on the back that elicit a feeling of warmth or heat and may or may not be accompanied by pain. Back burning sensation may also be accompanied by a wide variety of other symptoms, some of which may include feelings of tingling or numbness (paresthesia) or itching. A host of underlying events or conditions may cause back burning sensations.
The Moonâs synodic period is the time between successive recurrences of the same phase; e.g., between full moon and full moon. The synodic period of a planet is the time required for the Earth to overtake it as both go around the Sunâor, in the case of fast-moving Mercury or Venus, for the planet in question to overtake the Earth.
As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days catching up because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth. At the new Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated (position 1 in illustration). In other words, the Moon is between Earth and Sun. At first quarter, the half-lit Moon is highest in the sky at sunset, then sets about six hours later (3).
