The distance from the Earth to the Sun is about 150 million kilometers all the time

The distance from the Earth to the Sun is about 150 million kilometers all the time (this distance varies quite a bit during the year) How fast is the Earth moving relative to the Sun?

Given:

R = 150 * 10 ^ 6 kilometers – the distance from the Earth to the Sun;

pi = 3.14 – geometric constant;

T = 1 year = 365 days = 8760 hours – the time it takes for the Earth to complete a revolution around the Sun.

It is required to determine v (km / h) – the speed with which the Earth moves around the Sun.

The Earth moves around the Sun in a circular orbit with a radius R. Then the circumference of this orbit will be:

L = 2 * pi * R.

Then the speed of the Earth is equal to:

v = L / T = 2 * pi * R / T = 2 * 3.14 * 150 * 10 ^ 6/8760 =

= 6.28 * 150 * 10 ^ 6/8760 = 9420 * 10 ^ 5/8760 = 1.08 * 10 ^ 5 kilometers per hour =

108,000 km / h

Answer: the speed of the Earth around the Sun is 108,000 km / h.
