how long does it take the earth to travel around the sun?

Question

in days please

give reasons

give good reasons

Answer 1

365.25 days.

Which is why there are 365 days in a year, but 366 every 4 years.

I hope that helps.

Additional: Give reasons? Mass of earth, mass of sun, distance from sun... It's simple astro-physics. How long would you *like* it to take?

Additional v2: Good reasons? Any planet with the same mass as the Earth orbiting any star with the same mass as the Sun, at the same distance as we are from our sun (roughly 93 million miles) will take 365.25 days to orbit. It's gravity. There's no getting away from it! ;-)

Answer 2

It takes 365.25 days for the Earth to go round the Sun (a year). As for reasons, well, the reason is that that's how long it takes.

If the Earth was closer to the Sun it would be shorter, if it was further away it would be longer. It takes that long because of how large our orbit around the Sun is.

Answer 3

1 year exactly - 365.25 days = 8876 hours.
the .25 od a day is why we have a leap year every 4 years

is is due to the gravitational pull of the sun that the earth goes round it - why it takes 365 days is due to a huge multitude of forces - the size of the earth, the distance it is from the sun, the spinning of the sun itself, forces from all the little parts that joined to make the earth, the collision of the earth with another large rock that formed the moon, the moon itself etcetcetc. It would take the biggest supercomputer years to eplain the exact forces that explain why it takes exactly as long as it does.

Answer 4

It takes one Side Real Year for the Earth to orbit around the Sun as viewed relative to a star its aprox 366.25 (three hundred sixty six & one quarter )Side Real days in neglecting the seconds that the Earth slows down over time and increases it orbital radius.
That means the Earth orbit is not static but is dynamic it follows the rules of gravity.

Answer 5

It takes 365 days or 1 year. 1 day = one rotation of the earth on its axis. and 1 year = the time it takes the earth to go around the sun from where it starts = as the 3rd planet from the sun.

Answer 6

Hi. A little over 366 days. During that time the Sun has traveled around the Earth's sky so we only 'see' a little over 365 days.

Answer 7

it takes the earth one year to go around the sun. by definition one year is the time earth takes to go around the sun in days it is i think 365.25 days. this .25 days is not counted and we take it as 365 days after every 4 years we have a leap year which has 366 days (this counts for those .25 days left out), in a leap year Feb has 29 days not 28.

Answer 8

Several different types of year are defined, with differing lengths, depending on the reference point chosen. An anomalistic year is one revolution relative to perihelion (point in time when a planet is closest to the sun) and equals 365.25964 days. An eclipse year is one revolution relative to the same node of the moon's orbit - equal to 346.62003 days. A sidereal year is one revolution relative to the fixed stars and equals 365.25636 days. A tropical, or solar, year is one revolution relative to the equinoxes. It is equivalent to 365.24219 days. For convenience, the civil (calendar) year is set at a whole number of days, usually 365 but 366 in a leap year.

Answer 9

actually the orbital period is 365.26 days. the earth orbits the sun at an average speed of 108,000kph (67,000mph) in an anticlockwise direction. like the other planets, earth orbits the sun along an elliptical path. earths spin axis is tilted at an angle of 23.5' meaning the earth spins once every 23.93 hours. even though the earth is 3 per cent closer to the sun in january(perihelion) than in july (aphelion) it will still spin the same.

Answer 10

365 1/4 days. A whole year.
