Sidereal Period
The 'fixed stars' provide a useful reference frame for measuring the motions of celestial bodies. Relative to the stars, the sidereal period is the time it takes for a planet to complete one orbit.

Sidereal Period
The time it takes for a planet or satellite to make one complete circuit of its orbit (360°) relative to the stars. Earth's sidereal period (or sidereal year) is equal to 365.2564 mean solar days.

SIDEREAL PERIOD
The sidereal period is the time it takes a planet (or other body) to complete one orbit around the sun (with reference to the stars). It is usually expressed in Earth years.
Sidereal periods are "physical," in the sense that they are the quantities to which the laws of Kepler and Newton refer.
The Sidereal Period is the time taken by the planet to return to the same place in its orbit, relative to the stars.
sidereal period the period of revolution of one object around another measured with respect to the stars (e.g., for the Moon, it is 27.3 days).
The time it takes an object to complete one revolution with respect to the stars is called a sidereal period. The Moon has a sidereal period of 27.3 days and a synodic period of 29.5 days. The Earth has a sidereal period of 365.

With an orbital period (sidereal period) of 164.88 Julian years, Neptune will soon return (for the first time since its discovery) to the same position in the sky where it was discovered in 1846.
The Moon's orbital period, measured by the stars ("sidereal period") is 27. 321662 days. However, the monthly cycle of the Moon--thin crescent to half-moon, to full and back to crescent--takes 29.
The period of one revolution of a planet's orbit is known as its sidereal period or year.
This would be the Moon's Sidereal Period since it is the time for the Moon to be back in the same location relative to the stars, and this is also the time for one orbit. How long does it take for one rotation (spin) on its axis?
Venus spins retrograde with a sidereal period of 243.01 days. It has an orbital period of 225 days, so its solar period (Venus day) is 117 earth days. The sidereal rotation period is very close to a resonance with Earth at 243.
This is called the sidereal period (which means the period relative to stars).
Sidereal period 27d7h43m11s, e = 0.0549, inclination of orbital plane to ecliptic 5°8'43". Obliquity 6°41'. Synodic period 29d12h44m2s.9. Vorb = 1.02 km s-1. Albedo 0.07.
