What is the exact time taken by earth to revolve around the sun?

Answer 1

365 days....

Answer 2

The Earth takes approximately 365 1/4 days to complete 1 revolution around the sun.

Answer 3

Earth takes 365 days,6 hours to revolve around sun so every four years there is one day extra and every 400 years 1 day is added because there are some minutes and seconds extra.

Answer 4

Most of the answers here are not totally correct.

The amount of time it takes for Earth to make one complete orbit of the sun (the sidereal year) is currently 365.25636 days, or 365 days, 6hrs, 9mins, 9secs. The way we measure a year however is based on the position of the sun in the sky. The vernal equinox year (a particular type of tropical year), the year on which solar the Gregorian calendar used in a vast majority of the modern world is loosely based on, is 365.2424 days. It is slightly shorter than the sidereal year because of the precession of Earth's rotational axis. A tropical year is based on the intersection of the ecliptic with the celestial equator, and the precession of the Earth's axis causes this intersection to change over time. The length of a tropical year varies slightly depending on where you measure the start and stop point of the year, but the mean tropical year is the average of all possible tropical years, and is 365.24219 days.

The Gregorian year is 365.2425 days (a tad longer than the vernal equinox year).

Answer 5

The Earth rotates about on a fixed plane that is tilted 23.5° with respect to its vertical axis around the sun.

The average time the earth takes to move around the sun in approximately 365 days. This path that the earth takes to revolve around the sun is called the elliptical path.

The Earth needs 23hrs 56mins to complete one true rotation, or one sidereal period, around the sun. The solar day, on the other hand, is the time needed for a point on earth pointing towards a particular point on the sun to complete one rotation and return to the same point. It is defined as the time taken for the sun to move from the zenith on one day to the zenith of the next day, or from noon today to noon tomorrow. The length of a solar day varies, and thus on the average is calculated to be 24hrs.

Answer 6

The time taken is 365 days 5 hours and 54 minutes . Roughly : 365.24 or 365 1/4 days .

Answer 7

Time is relative . time cannot be identified unless there is a reference point to measure it from.The orbit of the earth relative to the sun continully changes.The motion of the Solar system relative to the Galaxy also continually changes.
Therefore we are not able to determine an exact time,Since time continually changes as a function of Gravitational motion.

Answer 8

It takes 365 and 1/4 days. That is why we have a leap year every four years.

Answer 9

365 days 5 hours 56 minutes.

Answer 10

365 days 5hours 56 minutes 45.51seconds
this is the result derrived frm laws of gravitation and kepler's law.
earth's orbit is elliptical always ,sun is at one of the foci .
all astronomical measurements are tested and correct as u must have heard about other predictions like that of eclipses

Answer 11

a year.
no two revolutions are exactly the same time as the path is always different so no matter what the time taken in any given revolution that is exactly a year.
