List of 21st-century lunar eclipses
This list of lunar eclipses of the 21st century contains all lunar eclipses, which can be observed in this century from the earth, including the Halbschattenfinsternisse.
Survey
In the 21st century, a total of 228 lunar eclipses take place. There are 78 years in which eclipses take place only two, what is the minimum possible number of eclipses in one year. The theoretical maximum of five eclipses in a year there are in the 21st century ever before. The four eclipses occur in the years 2009, 2020, 2038, 2056, 2085 and 2096th
The number of different types of lunar eclipses in the 21st century is as follows:
In 5 of the 86 Halbschattenfinsternisse the Moon completely immersed in the penumbra of the earth one without entering the umbra; Such eclipses are referred to as total penumbral eclipse. In 3 of the 57 partial umbra - lunar eclipses of the moon does not penetrate completely into the penumbra one. For 24 of the 85 total lunar eclipses the shadow axis strikes the lunar surface, it is central total eclipses, which are the darkest shadows and darkness with the longest duration. For this darkness type also includes the longest eclipse of July 27, 2018, a totality duration of 1 hour 42 minutes and 57 seconds.
Legend
The following table contains all lunar eclipses of the 21st century. It contains the following columns:
- Time: The time of maximum eclipse. The time is shown in Terrestrial dynamic time ( TDT ). This Universal Time (UT ) runs ahead increasingly. At the beginning of the century, the difference between TDT and UT was 64 seconds ( At), towards the end of the century, a value of 204 seconds is assumed.
- Type: Possible types are semi-shade, Partial or Total. In penumbra eclipse, it is possible that the moon is completely immersed in the penumbra cone of earth without it enters the umbra cone. These eclipses are also known as total Halbschattenfinsternisse and are made by the addition of " total" marked. In total lunar eclipses distinction is whether the shadow axis hitting the moon throughout the eclipse curve or missed him. Eclipses, where the shadow axis Meet the Moon are marked by "central".
- Saros: The number of the Saros cycle, which belongs to the darkness. If the number is odd, a descending lunar node finds the darkness near place, it is just rising on one. This is exactly opposite to that of solar eclipses.
- Gamma: Gamma value of a lunar eclipse, this corresponds to the smallest distance of the shadow axis from the center of the Moon, measured in units of the equatorial radius of the Earth. Passes through the shadow of the Moon's center axis north, the gamma value is positive otherwise negative.
- Size: The size is specified for the half - and umbra. It corresponds to the proportion of the diameter of the moon, which is more than covered by the half or umbra cone.
- Duration: The duration is specified in hours and minutes, it can be distinguished up to three values depending on the type of darkness: Penumbra: time between the inlet and outlet of the moon in and out of the penumbra
- Partial: time between the inlet and outlet of the Moon in or from the umbra. Closes the total phase, if necessary, with a.
- Total: period during which the moon is completely in the umbra.
