Why does it take Earth 365 days to orbit the sun?

-------------------------------------------------------

Clive say: Because it does.
-
Kiki say: cuz she dummy thicc
-
Ronald 7 say: Because of the time it takes to two halves of its Solar Orbit and the distance that it takes
-
goring say: The Earth orbits the barry center which is the fulcrum between the earth and the Sun.

The motion of the sun and the earth are relative to the center of mass of the galaxy. any mass loss from the center of mass of the galaxy will affect the speed of the solar system ,hence the spin of the earth would change accordingly.

Thus the days of the earth will become longer as the years go by.
-
YKhan say: Due to Kepler's Laws of motion, especially the 3rd Law. The mass of the Sun plus the distance of the Earth from the Sun's center determines the orbital period.
-
Athena say: Speed of orbit plus circumference from the sun.
-
Donut Tim say: It is because of Earth's distance from the Sun.
The closer the orbit, the less time it takes. The planet Mercury is a little less than half as far from the sun and only takes around 88 days for one orbit.
-
Angel Mendez say: cuz it cant speed up or slow down unless pushed or pulled
-
say: Because there are lots of turds on the planet weighing it down so it’s not as fast
-
say: I blame Obama
-
Helmuth say: because ur mom is so fat she slows down the rotation
-
stephen say: It hasn't allows taken that amount of time if we go back Millions of years.
-
Bill say: Kepler; T^2 is proportional to R^3
Where T is the orbital period and R is the distance from the Sun.
You can use this simple formula to work out the planets year o distance from the sum referenced to Earth.
-
az_lender say: The speed is governed by (a) the distance from the earth to the sun, (b) the mass of the sun, which exerts a large gravitational force on the earth, and (c) the speed is then necessary, to provide enough centrifugal force, to exactly balance the gravitational force.
-
Bill-M say: The distance of the Earth from the Sun and the Speed of the Earth in it's orbit.
-
Poseidon say: I doesn't.

It take 365 and a quarter days to orbit the Sun.

This is why every 4 years we have a Leap Year in February which adds one day to February every 4 years and its February 29th. Basically we are playing 'catch up'.

The next Leap Year will be on 29 February 2020.
-
busterwasmycat say: because where it is requires that. The mass of sun and earth, and the distance, impose a force of gravity, and that imposes a rate of motion (or it would not stay where it is, yet it does). Why does the earth turn around 365 times while making that trip? That is just luck, where we are in time. It doesn't have to be that and it didn't used to be that, and it won't stay that, but it has to be something, and 365 (and change) is what it is now.

Adullah M say: It is actually 365.25 days per Solar year ,so every four years then we get one day added on the 29th of February ,as we call its leap year.
At the same time the moon orbit the earth 12 months per year ,having the average times of 354.75 days per Luna year .So the average days per year of both systems is 360 days .
Then this figure of 360 is being used as the total angles of a circle having 360 degrees. Again the average days per month of both systems of having 12 months , then equal to 30 days. By this token , mankind then use calculation for the time dimension ,on the base of 60 ie; 60 secs. ,60 mins. and 24 hours per day. More over if the length of the circumference of a circle is 22 units the length of its diameter would be 7 , so 22/7 = the constant of a circle or Pi.

So mankind divide a month in to weeks having 7 days per week ,as we are using this system of counting of time dimension up till now ,internationally .
-
Chris Ancor say: To match the length of a year. Amazing.
-
derfram say: Because that is the period of a stable orbit 93 million miles from the sun.
-
CarolOklaNola say: It's 365. 2422 days for a tropical solar day, AND Earths orbit is NOT circular. The Sun's AND the Earth's mass and gravity AND inertia AND conservation of momentum, energy and mass are why one tropical solar year is 365.2422 days long. Those numbers to the right of the decimal point are important. They can be the difference between life or death. Bring constantly overdosed with long acting insulin for 3 months was NOT "fun."
-
Razer say: bc math
-
Susie say: That’s a question for the maker.
