## What are the synodic and sidereal periods of a planet quizlet?

The synodic period refers to the planet’s period with respect to the Earth’s motion, whereas the sidereal period is the true period with respect to the background stars. The observation showed that bodies can orbit an object other than the Earth.

### What does a planet’s synodic period mean or represent?

the time interval during which a planet, moving in orbit around the sun, returns to its former position relative to the sun as seen from the earth. The synodic period represents the time necessary for the repetition of a planet’s configuration. …

What is a synodic period and how will you determine it?

A synodic period is the time it takes for an astro-body to return to the same angular position from the Sun as seen from the Earth. The term is usually used for the Moon and the planets. For the Moon the synodic period is the lunar month of 29.531 days on average.

Why are sidereal and synodic periods different?

However, because the Earth is constantly moving along its orbit about the Sun, the Moon must travel slightly more than 360° to get from one new moon to the next. Thus, the synodic month, or lunar month, is longer than the sidereal month. A sidereal month lasts 27.322 days, while a synodic month lasts 29.531 days.

## What is a sidereal period quizlet?

The sidereal period is the time required to complete one full orbit as viewed from a stationary point such as the stars. The synodic period is the time required to complete one full set of phases like new moon to the next new moon.

### What is the difference between sidereal and synodic periods?

The Sidereal and Synodic Months. The sidereal month is the time the Moon takes to complete one full revolution around the Earth with respect to the background stars. Thus, the synodic month, or lunar month, is longer than the sidereal month. A sidereal month lasts 27.322 days, while a synodic month lasts 29.531 days.

What is Mercury’s sidereal period?

What is sidereal period of Earth?

The sidereal period of the Earth is 365.25636 mean solar days, which is slightly longer than the tropical year (measured between successive vernal equinoxes) of 365.24219. In most calendar systems, the length of the year is taken to be 365 days, which is close to the Earth’s sidereal period.

## What is the difference between sidereal and synodic month?

### What is the difference between a sidereal year and a tropical year?

What does synodic month mean in astronomy?

The synodic month, or complete cycle of phases of the Moon as seen from Earth, averages 29.530588 mean solar days in length (i.e., 29 days 12 hours 44 minutes 3 seconds); because of perturbations in the Moon’s orbit, the lengths of all astronomical months vary slightly.…
