# Saros

### What is a saros period?

One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros. A series of eclipses that are separated by one saros is called a saros series. It corresponds to:

### What is saros series 120?

Solar eclipses of Saros 120 all occur at the Moon’s descending node and the Moon moves northward with each eclipse. The series began with a partial eclipse in the southern hemisphere on 0933 May 27. The series will end with a partial eclipse in the northern hemisphere on 2195 Jul 07. The total duration of Saros series 120 is 1262.11 years.

### How does the saros series work?

Each saros series starts with a partial eclipse (Sun first enters the end of the node), and each successive saros the path of the Moon is shifted either northward (when near the descending node) or southward (when near the ascending node) due to the fact that the saros is not an exact integer of draconic months (about one hour short).

### How do you determine if an eclipse is a Saros series?

If there is an eclipse one inex (29 years minus about 20 days) after an eclipse of a particular saros series then it is a member of the next series. For example, the eclipse of October 26, 1961 BC is in solar saros series 2.

### What happens during a saros period?

One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros. A series of eclipses that are separated by one saros is called a saros series.

### How many days are there in a Saros series?

The saros is not an integer number of days, but contains the fraction of ​ 1⁄ 3 of a day. Thus each successive eclipse in a saros series occurs about eight hours later in the day.

### What is the Saros cycle of lunar eclipses?

A saros cycle of Lunar Eclipses encompasses around 45 lunar eclipses over a period of around 800 years. The long periods of time involved make the saros cycle interesting for astrological interpreters of history.

### What is a Saros series?

A series of eclipses that are separated by one saros is called a saros series. It corresponds to: The 19 eclipse years means that if there is a solar eclipse (or lunar eclipse ), then after one saros a new moon will take place at the same node of the orbit of the Moon, and under these circumstances another eclipse can occur.

### What is the Saros cycle in astronomy?

…and important cycle was the saros, essentially an eclipse cycle. There has been some confusion over its precise nature because the name is derived from the Babylonian word shār or shāru, which could mean either “universe” or the number 3,600 (i.e., 60 × 60).
