How fast is the earth?

Answer 1

The speed of Earth, or of anything else, must be specified in relationship to something else. If you mean the speed of Earth around the Sun, that's about 30 kilometers per second. If you mean the speed of Earth around our Galaxy, or related to the center of the Local Group, etc., you will get different answers.

Answer 2

The mean orbital speed of our Earth is 29.78 km/s. The max. orbital speed is 30.29 km/s and the min. orbital speed is 29.29 km/s. 1 kilometre = 1,000 metres. Scroll down to related links and look at "Williams, David - NASA Goddard Space Flight Center".

Answer 3

A point at the Earth's equator moves approximately 27907 meters east in one minute.

The Earth rotates 360 degrees around its axis in approximately 1436 minutes (the siderial day). The estimated circumference of the Earth is 40,075,160 meters. Thus the a point on the Earth's equator moves 40,075,160 meters in 1436 minutes. 40,075,160 meters / 1436 minutes = 27907 meters/min.

The term 'rotate' is generally used when describing the Earth's motion around its own axis. The term 'revolve' is uses to describe its motion around the sun.

Answer 4

Just to make it a lot simpler, we'll assume the earth's orbit is a circle, with the sun

at the center. Then the average speed is

(circumference of the orbit) per year.

Radius of the orbit = 93 million miles

Circumference = 2 pi R = 186 million pi miles

And there it is ! The average speed is 186 million pi miles per year,

with respect to the sun.

To boil it down to units that we have a better feel for:

(186 million pi miles per year) x (1 year per 365.23 days x 1 day per 24 hours) =

66,663 miles per hour (rounded)

18.52 miles per second (rounded)

29.8 kilometers per second (rounded)

Answer 5

You seem to have stuffed two questions into one.

-- The speed of light through space is about 300,000,000 meters per second.

-- At that speed, it takes sunlight about 500 seconds (81/3 minutes) to reach Earth.

Answer 6

The general figure of the Earth's mean orbital speed in terms of miles per second is 18½ miles per second. Let x be the Earth's mean orbital speed as defined based on the sidereal year. This speed is:

x = (9.399511 x 1011) / (3.155815 x 107)

= 2.978473 x 104 m/s

Let vt be the Earth's mean orbital speed as defined based on the tropical year. This is:

vt = (9.399511 x 1011) / (3.155693 x 107)

= 2.978589 x 104 m/s

Answer 7

The earth is about 200 to 900 miels per hour and you can not feel it cause the gravity is so storng

Answer 8

This is a very simple operation: 1700 km ? km

3600 sec 1 sec 1700 km 0.47 km

3600 sec 1 sec 1700 km 470 m

3600 sec 1 sec =470 m/s=

Answer 9

The earth's speed around the sun is approximately 30k m/s:

v=sqrt(GM/r)= sqrt(2/3(e-10)2e30/150e9)=29,814m/s.

Answer 10

Relative to the sun, the Earth's speed in its orbit is about 29,800 meters per second.
