Understand the moon phases and you can wager a pretty good guess for when the next full moon is no matter where we are in the lunar cycle. Here's how.
As the Moon waxes (the amount of illuminated surface as seen from Earth increases), the lunar phases progress through the new moon, crescent moon, first-quarter moon, gibbous moon, and full moon phases. The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon.
For example, a last quarter rises at midnight and sets at noon. [5] A waning gibbous is best seen from late night to early morning . [ 6 ] The Moon rises 30 to 70 minutes (should be a fixed number, about 50 minutes, if it's the same 13 degrees) later each day /night than the day/night before, due to the fact that the Moon moves 13 degrees every ...
When the moon is nearly full, it is called a gibbous moon. The crescent and gibbous moons each last approximately a week. [5] Each phase is also described in accordance to its position on the full 29.5-day cycle. The eight phases of the moon in order: [5] new moon; waxing crescent moon; first quarter moon; waxing gibbous moon; full moon; waning ...
Best visible shortly before or after a new moon (during the waning and waxing crescent phases respectively), Earthshine is the faint glow of the non-illuminated (night) side of the Moon caused by sunlight reflecting off the surface of Earth (which would appear nearly full to an observer situated on the Moon at this time) and onto the night side ...
Looking at the diagram, note that when the Moon's line of nodes (N1 & N2) rotates a little more than shown, and aligns with Earth's equator, the Moon's orbit will reach its steepest angle with the Earth's equator, and 9.3 years later it will be the shallowest: the 5.14° declination (tilt) of the Moon's orbit either adds to (major standstill ...
It is a gibbous phase when it approaches or leaves the opposite side of the Sun. It shows a quarter phase when it is at its maximum elongation from the Sun. Venus presents a thin crescent in telescopic views as it comes around to the near side between the Earth and the Sun and presents its new phase when it is between the Earth and the Sun.
Simplified schematic of only the lunar portion of Earth's tides, showing (exaggerated) high tides at the sublunar point and its antipode for the hypothetical case of an ocean of constant depth without land, and on the assumption that Earth is not rotating; otherwise there is a lag angle.
