How fast does Earth revolve?

Answer 1

The planet Earth completes a complete revolution of the Sun (year) in 365.25 days, each of which is 24 hours or 86,400 seconds in duration. For its mean orbital circumference of 292 million miles (470 million km), the Earth travels at an average orbital speed of 66,622 mph (107, 218 km/hr or about 30 km/sec).

Answer 2

Earth revolves around the sun once every 365.24 tropical days, or once every 365.26 sidereal days.

A tropical day is the average time for the Earth to revolve about its axis relative to the sun. A sidereal day is the average time it takes for the Earth to revolve about its axis relative to a far distant star. The difference lies in the fact that the Earth is rotating about its axis at the same time it is orbiting around the Sun.

Answer 3

The earth travels approximately 585 million miles around the Sun in our orbit

every year. That boils down to approximately;

1,600,000 miles/day

or 66,666 miles/hour

or 1,111 miles/minute

or 18.51 miles/second

Suffice to say we are moving rapidly through space relative to our Sun.

The math is relatively easy.

93,000,000 miles earth to sun times two for diameter.

Diameter times pi (3.14) = 585,000,000 miles around.

Answer 4

The question has no meaning. According to the Theory of Relativity, it is impossible to determine a privileged frame of reference, so the best that can be done is to state the Earth's velocity relative to some other specified object. Obviously, this will depend on what other object is chosen. If it's the Sun (a reasonable choice), then the Earth moves at an orbital velocity of about 66000 miles per hour.
