how fast does the earth travel around the sun?

Answer 1

365 & 1/4 days for one round, roughly take a year to do so!

since 1 circle is 360 degree, its 360/364.25 ~ 0.988 degree per days, almost 1 degree per day.
We are 91 to 94.5 million miles from the sun,
average 92.75 million miles apart,

Rotating 0.988 degree ~ 0.01725 radians per day
a distance of 92.75 x 0.01725 x 10^6 miles a day
~ 1.6 million miles a day !!!!

Answer 2

At approximately 66000 miles per hour.
The Earth's orbit around the Sun is an ellipse, NOT a circle.
The Tudor age astronomer Johannes Kepler studied the Earth's orbital properties, and stated that when the Earth is furthest from the Sun it travels slowest and when nearest the Sun it travels fastest.
Later astronomers found a mean distance between the Earth & Sun of 92000000 miles.
Approximating all this by using the circumference of a circle equation (C = 2 pi r), where 'r', the radius, is the mean distance from Earth to Sun, the circumference (one full orbit of the Earth can be found. 5.78 x 10^8 miles.
The number of hours in 1 year is 24 x 365 = 8760 hours.
Finally, using the eq'n speed = distance/time
.speed = 5.78 x 10^8 / 8760 = 65981.7 miles per hour, or 66000 miles per hour.
NB This a very crude approximation, because of the assumptions used, but it gives a guide. The Royal Astronomical Society can probably offer more detailed guidance and advice.

Answer 3

Doing the math:

Average distance from earth to sun = 93,000,000 miles. That's a roughly accurate figure to use as a radius of a circle (note: earth's orbit is not circular, but it's very close. On an "ellipse eccentricity scale" of 0 to 1, Earth's eccentricity is about 0.016, meaning it's very nearly a circle).

Get circumference from a radius: 2*[pi]*radius = 584,335,740 miles in one orbit.

Divide circumference by days/year: 584,335,740 / 365.25 = 1599824 miles per day

Divided by 24 hours: 1599824/24 = 66659 mph

Again, those are rough numbers. As you can see by other responses, the calculations are varying within a certain order of magnitude (+/- 1000 mph).

Answer 4

Boy you have a bunch of bad answers here. Light takes eight minute to reach earth from sun so radius is 8 x 60 x 186,000 miles giving you a diameter of twice that. them multiply by pie and you have the circumference. Divide that by the hours in a year and you will get an approximate speed. Not exactly right as the orbit is not round and ome numbers wer rounded off.

Answer 5

The duration of 1 orbit is 365 days and a little short of 6 hours. With a radius of 149,597,900 Kilometres, the average speed of the Earth in its orbit about the sun is around 29,790 metres per second (about 66,700 miles per hour).

Answer 6

properly, Earth is approximately ninety 3 million miles from the sunlight, and all of us comprehend it takes 365.25 days to end an orbit. So... utilizing the formula to locate the circumference of a cirlce - C = 2 X pi X r - we get: C = 2 x (3.141529) x ninety 3,000,000 miles = 584,324,394 miles divide the style of miles via the time elapsed, you get: 584,324,394 / 365.25 = a million,599,793 miles according to day and, divide this via 24, you get sixty six,658 miles according to hour

Answer 7

Averages about 66,000 mph
Math: Circumference = Pi x Dia
3.1416 X 186,000,000 = 585,156,000 miles per year
Devide by 365 days = 1,630,167 miles per day
Devide by 24 hours = 66,798 miles per hour

Answer 8

It's about 18.5 miles/second, or around 66,000 miles/hour.

Answer 9

Not sure on MPH or anything, but it does take 364.5 days to make the complete loop. That's where we get our year!

Answer 10

66.000 miles per hour.
