Most years have 12 Full Moons, one each month. When a Full Moon is close to the apogee, it is called a Micromoon. When a Full Moon is close to the perigee, it is known as a Supermoon or Super Full Moon. The point of the Moon's orbit closest to Earth is called perigee, and the point farthest away is known as apogee. On the other hand, solar eclipses happen if the Moon comes close to the lunar nodes around New Moon.Ī red Moon during a total lunar eclipse on September 28, 2015. When this happens, Earth casts its shadow on the Full Moon, causing a lunar eclipse. These are the points where the Moon's orbit crosses the ecliptic, which is the Sun's path, seen from Earth.
Two or three times a year, the Full Moon phase coincides with the Moon reaching the lunar nodes of its orbit. In special cases, however, the effect of refraction (as well as the tilt of the Moon's orbit) means that it is possible for the Sun and the Full Moon to be visible at the same time. Generally speaking, at the precise moment of the Full Moon alignment, the Moon is only visible in the night part of Earth. The Full Moon is visible in the sky from around sunset to sunrise. When the side of the Moon we can see from Earth is fully lit up at Full Moon, the other side is in darkness. The technical term for when three bodies-such as the Sun, Earth, and the Moon-are in alignment is syzygy. That can make it tricky to tell the difference between a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.įull Moon is when the Sun and the Moon are aligned on opposite sides of Earth. Still, the Moon can appear to be full a day before or after when more than 98% of the Moon's disc is lit-up. This means the exact time for Full Moon is during the day on parts of the planet. The Moon is in constant motion around the Earth, so-technically speaking-the Full Moon only lasts for an instant of time. If the Full Moon occurs at a moment when the Moon is above or below the ecliptic, we view the Moon at an angle that diminishes the illumination percentage by a tiny amount. The reason why we cannot see the entire illuminated hemisphere of the Moon during some Full Moons is that the Moon's orbit around Earth is inclined at an angle of about 5° in relation to the Earth's orbital plane, the ecliptic. That said, some Full Moons are only 99.9% illuminated, as seen from Earth. The Full Moon is when the Sun and the Moon are aligned on opposite sides of Earth, and 100% of the Moon's face is illuminated by the Sun (see illustration). Times and dates are based on the local time in Odesa. Times for the Full Moon vary by time zone. Our mobile observatory will be in Roswell, New Mexico, in the US to capture it for you.
