The Mercury-Mars synodic period is 100.888 days.
Certain spacecraft orbits, Sun-synchronous orbits,have orbital periods that are a fraction of a synodic day.
This period of 223 synodic months is called a saros.
The synodic day is distinguished from the sidereal day, which is one complete rotation in relation to distant stars.
Such months(lunations) are synodic months and last approximately 29.53 days.
A synodic day is the period it takes for a planet to rotate once in relation to the star it is orbiting(its primary body).
When combined with the EarthâMoon system's common orbit around the Sun,the period of the synodic month, from new moon to new moon, is 29.53 days.
The 8-year cycle(99 synodic months, including 3 embolismic months) was used in the ancient Athenian calendar.
The moon is represented by a sphere that makes a complete orbit once every 29.53 days exactly,which corresponds to the synodic period of our natural satellite.
For Earth, the synodic day is known as a solar day, and its mean length is 24 hours and 2.5 ms.[1].
The average calendrical month, which is 1/12 of a year, is about 30.44 days,while the Moon's phase(synodic) cycle repeats on average every 29.53 days.
A synodic day is from"sunrise to sunrise", whereas a sidereal day is from the rise of a given star of reference to the next.
Their complex luni-solarcalendar, deciphered by ManuelIzquierdo based on work by Duquesne, followed three different sets of years,where the sidereal and synodic months were represented.
The synodic month(full moon to full moon) averages 29.530589 days, which is shorter than every calendar month in the year except February.
The next approximation(arising from continued fractions) after the Metonic cycle(such as a 334-year cycle)is very sensitive to the values one adopts for the lunation(synodic month) and the year, especially the year.
However, the length of any one synodic month can vary from 29.26 to 29.80 days due to the perturbing effects of the Sun's gravity on the Moon's eccentric orbit.
A solar year could be more evenly divided into weeks of 5 days, and the moon phases five-day and six-day weeks make a better short term fit(6 times 5 is 30)to the lunar(synodic) month(of about 29.53 days) than the current week(4 times 7 is 28).
This synodic month is longer than the time it takes the Moon to make one orbit around the Earth with respect to the fixed stars(the sidereal month), which is about 27.32 days.
This cycle corresponds fairly closely to 151 Mars orbits, 284 Earth orbits,and 133 synodic periods, and is analogous to the cycle of transits of Venus from Earth, which follow a cycle of 243 years(121.5, 8, 105.5, 8).
The lunar synodic cycle- the moon's regular journey from full moon to full moon again over 28 nights- causes changes in the Earth's magnetic field, the moon's gravitational pull on Earth, and light levels at night.
From the Moon,the Earth phases gradually and cyclically change over the period of a synodic month(about 29.53 days), as the orbital positions of the Moon around the Earth and of the Earth around the Sun shift.[ 1][ 2][ 3][ 4][ 5][ 6].
The synodic day is not constant, and changes in length slightly over the course of the year due to the eccentricity of the Earth's orbit around the Sun.[5][6] This change accounts for some of the difference between the mean and apparent solar time in the equation of time.
As viewed from Earth during the year, the Sun appears to slowly drift along an imaginary path coplanar with Earth's orbit, known as the ecliptic,on a spherical background of seemingly fixed stars.[3] Each synodic day, this gradual motion is a little less than 1° eastward(360°/year or 365.25 days/year), in a manner known as prograde motion.
However, the length of any one synodic month can vary from 29.26 to 29.80 days due to the perturbing effects of the Sun's gravity on the Moon's eccentric orbit.[3] In a lunar calendar, each month corresponds to a lunation.
