The time required for the Earth to move around its orbit, relative to the fixed stars. Equal to the time required for the Sun to move around the Ecliptic, relative to the fixed stars.
the time required for the Earth to complete an exactly 360° orbit around the Sun as measured with respect to the stars = 365.2564 mean solar days (contrast with tropical year).
The time required for one complete revolution of the earth around the sun, relative to the fixed stars, or 365 days, 6 hours, 9 minutes, 9.54 seconds in units of mean solar time.
the time for the earth to make one complete revolution around the sun, relative to the fixed stars
Period of the Earth's revolution about the Sun with respect to the stars.
Time of one orbital revolution of the earth about the sun, with a fixed stellar object as reference.
The time it takes Earth to complete one orbit of the Sun relative to the stars or 365 days 6 hours 9 minutes and 10 seconds. It is also the time it takes the Sun to travel once around the sky relative to the stars.
The period of time required for Earth to complete one revolution around the sun in relation to the fixed stars: 365 days, 6 hours, 9 minutes and 9.54 seconds. Because of Earth's precession, this is 20 minutes longer than the mean tropical year.
the amount of time it takes one body to revolve about another with respect to the stars
A sidereal year is measured relative to the stars (the period between successive conjunctions with any star). One sidereal year, equal to 365 days, 6 hours, 9 minutes, and 9.5 seconds, is the period during which the earth completes one revolution around the Sun (this is the same as the time it takes to come into alignment with a particular star).
The time it takes the earth to complete one full orbit around the sun relative to the fixed stars.
The sidereal year is the time for the Sun to return to the same position in respect to the stars of the celestial sphere. The sidereal year is the orbital period of Earth. A sidereal year equals 365.25636042 mean solar days (which is 366.25636042 earth rotations or sidereal days; a true cycle will always compare two bodily objects that differ mathematically by exactly 1.)
