penumbral The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object of lesser size. In cases of equal or smaller impinging objects, only an umbra and penumba are generated. As ...

, 57 will be partial and 85 will be total. Of the total eclipses, 24 will be central, in the sense that the Moon will pass through the very center (axis) of the Earth's shadow (for more information see

gamma Gamma (; uppercase , lowercase ; ) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. In Ancient Greek, the letter gamma represented a voiced velar stop . In Modern Greek, this letter normally repr ...

). In the 21st century, the greatest number of eclipses in one year is four, in 2009, 2020, 2038, 2056, 2085, and 2096. The predictions given here are by

Fred Espenak Fred Espenak (August 1, 1953 – June 1, 2025) was an American astrophysicist. He worked at the Goddard Space Flight Center and published extensively on eclipse predictions. Career Espenak became interested in astronomy when he was 7–8 year ...

. The longest measured duration in which the Earth completely covered the Moon, known as totality, was during the lunar eclipse of July 27, 2018. This total lunar eclipse had a maximum duration of 1 hour, 42 minutes, and 57 seconds. The longest possible duration of a total lunar eclipse is 1 hour and 47 minutes. Lunar eclipses in the 21st century

The table contains the date and time of the greatest eclipse (in dynamical time, which in this case is the time when the axis of the Earth's shadow passes over the Moon; this is in (Ephemeris Time). The number of the saros series that the eclipse belongs to is given, followed by the type of the eclipse (either total, partial or penumbral), the gamma of the eclipse (how centrally the Moon passed through the Earth's shadow), and both the penumbral and umbral magnitude of the eclipse (the fraction of the Moon's diameter obscured by the Earth). For each eclipse, the duration of the eclipse is given, as well as the eclipse's contacts (the points at which the Moon reaches and exits the Earth's penumbra and umbra). Eclipses are listed in sets by
