Next Full Moon

The next Full Moon will occur on:

That's in 11 days, 7 hours and 3 minutes.

At that exact time the Moon will be at the distance of 399,740.1 kilometers (248,387.6 miles) from Earth and from Majuro, Marshall Islands [change location] it will be visible in the constellation of Ophiuchus. The precise celestial position of the Moon at that time can be viewed on our interactive sky map.

The apparent size of the Moon will be 0.50°.

Understanding the Full Moon

A Full Moon occurs when the side of the Moon facing Earth appears 100% illuminated by the Sun. This happens when Earth is positioned roughly between the Sun and the Moon, meaning the Moon is on the opposite side of Earth from the Sun.

Trajectory in the Sky

Because of the geometric configuration with respect to the Sun (also known as "opposition"), a Full Moon rises around sunset, reaches its maximum altitude around midnight, and sets around the time of sunrise.

Another interesting fact about the Full Moon's trajectory in the sky during the 24 hours, is that it roughly follows the Sun's path from the opposite season. This means that in winter the Full Moon will approximately follow the trajectory followed by the Sun during summer and vice-versa. That is why, for instance, full moons in winter reach high altitudes in the sky (as the Sun does during summer) and in summer they remain lower.

Interval Between Full Moons

The interval between two full moons is approximately 29.53 days, i.e. 29 days, 12 hours and 43 minutes. This time interval is also called a Synodic Month or Lunation. This is an average value; the actual interval can vary by several hours. This variation occurs primarily because the Moon's orbit around Earth is not perfectly circular, and also due to the Earth's elliptical orbit around the Sun.

Full Moon and Eclipses

A Full Moon can happen when the Moon transits across the shadow of the Earth projected into space. In such a situation a Lunar Eclipse occurs. Lunar eclipses do not happen at every Full Moon because the orbit of the Moon around the Earth is tilted with respect to the orbit of the Earth around the Sun. So, most of the time, a Full Moon passes above or below the shadow of the Earth.
