The cycle repeats once a month (every 29.5 days). These eight phases are, in order, new Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent. The rest of the month we see parts of the daytime side of the Moon, or phases. When sunlight reflects off the near side, we call it a full Moon. Because Earth is the third planet from the Sun, we are able to observe transits of both Mercury and Venus.When sunlight hits off the Moon's far side - the side we can't see without from Earth the aid of a spacecraft - it is called a new Moon. For example, when Mercury passes between the Sun and the Earth, this is called a transit of Mercury. A transit occurs when one celestial body passes between a larger celestial body and a third celestial body.There is also a phenomenon called a transit, which is similar to an eclipse, though not quite as visually stunning: The effect is so slight that a penumbral eclipse can be hard to recognize unless you know to look for it! Penumbral eclipses occur when the Moon enters only the faint outer edge of Earth’s shadow (called the penumbra), which causes the Moon to appear slightly darker than usual. A penumbral eclipse is a type of lunar eclipse.This results in a very bright ring of light called an annulus. Annular eclipses are similar to total solar eclipses (where the Sun is completely obscured by the Moon), but in an annular eclipse, the Moon’s apparent size is smaller than the Sun’s, meaning that the Sun is not completely obscured. ![]()
