In this way, how long is the sidereal year?
A sidereal day is 23 hours 56 minutes and 4.09 seconds long. A sidereal year is the time it takes for the sun to return to the same position with respect to the stars. Due to the precession of the equinoxes the sidereal year is about 20 minutes longer than the tropical year.
what is the sidereal period of the moon? The Moon's sidereal orbital period (the sidereal month) is ~27.3 days; this is the time interval that the Moon takes to orbit 360° around the Earth relative to the "fixed" stars. The period of the lunar phases (the synodic month), e.g. the full moon to full moon period, is longer at ~29.5 days.
Correspondingly, how long is the lunar month?
It's the duration between successive new moons. Also called a lunation or synodic month, it has a mean period of 29.53059 days (29 days 12 hours and 44 minutes). That's the mean, but the the true length varies throughout the year.
What is the difference between a sidereal month and a synodic month which is longer Why?
The reason the synodic month is longer than the sidereal month is because the earth orbits the sun at the same time the moon goes through its phases. By extension, the moon has to travel more than 360 degrees along its own orbit around the earth to cycle through all of its phases.
