All know that the Earth rotates around the Sun, but not all know the linear speed of Earth. Therefore, here we will give you everything about the linear speed of the earth to make you all aware of it. You all know that the earth is very important and the only planet on which humans can live comfortably. Therefore, scientists had researched a lot about the earth. They also measured the speed of the earth including the earth’s radius, diameter, and distance from other planets. It is considered that the earth revolves around its own axis and also around the Sun. Without further discussion let’s get started and know the linear speed of earth.
What Is The Linear Speed Of Earth?
The linear speed of earth is around 460 m/s or approximately 1,000 miles per hour. As per research, it is considered that the earth rotates once every 23 hours, 56 minutes, and 4.09053 seconds, called the sidereal period, and its circumference is approximately 40,075 km. In school, you learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of approximately 30 km/s or 67,000 miles per hour. In addition, our solar system, Earth, and all whirls around the center of our galaxy at some 220 km.s, or 490,000 miles per hour.
Here are the different linear speeds of the earth,
- The linear speed of earth around Sun is 67,000 miles per hour or 107,000 km/h
- The linear speed of Earth at equator is 465.185 m/s
- The linear speed of Earth rotation is 460 m/s
- The earth rotation speed per second is 460 m/s
- The speed of earth rotation is 1,000 miles per hour.
Now, you have the linear speed of the earth. Let’s understand how to calculate the speed of the earth.

Calculate The Linear Speed Of Earth
To calculate the speed of the earth you need a formula. By using that formula you can easily calculate the speed of the earth. As you know, the earth rotates in a circular motion therefore, in the formula the rotational speed of the earth is also included. Here is a formula to calculate the speed of the earth,
The linear speed of the earth(v) = r x w
Here, w – is the rotational speed of the earth and
r – is the radius of the earth
To calculate the rotational speed of the earth here is the formula,
W = (2 x pi)/T
Here, T – is the time period
Hence, the linear speed of the earth(v) = (2 x pi x r)/T
Let’s have an example to understand the above-given formula.
What is the linear speed of the point at the equator on the earth’s surface due to the rotation of the earth?
So, by using a formula,
The linear speed of the earth(v) = (2 x pi x r)/T
You know, the radius of earth(r) = 6400000 m or 6400 km and
Time period(T) = 24 hour = 24 x 60 x 60 = 86400s
By putting these values in the formula, ‘
The linear speed of earth = (2x 22 x 6400000)/(7 x 86400)
= 465.185 m/s
About The Earth
What can we say about the earth, it is the home planet. It is the 5th largest planet in the solar system and the third planet from the Sun. The single most outstanding feature of the earth is that its near-surface environments are the only places in the universe known to harbor life. It is designed by the symbol ♁. Earth appears bright and bluish in color when it is observed from the other planets. Easiest to see through a large telescope would be its atmospheric features, mainly the swirling white cloud patterns of midlatitude and tropical storms, which ranged in roughly latitudinal belts around the planet.
The surface of the earth is mainly divided into six continents namely Africa, Antarctica, Asia, Australia, North America, and South America. And these continents are surrounded by five major water bodies namely the Arctic, Atlantic, Indian, Pacific, and Southern oceans.

What Is Linear Velocity Of Rotation Of Earth?
Spinning. We are travelling (on the equator) at about 1,000mph. Escape velocity is 25,000mph.
What Is Linear Speed?
Linear speed is the measure of the concrete distance travelled by a moving object. The speed with which an object moves in the linear path is termed linear speed. In easy words, it is the distance covered for a linear path in the given time.
What Is Linear Speed Of Rotation?
The linear speed of a point on a rotating object can be determined by its distance from the center of the rotation. The angular speed is measuring the angle that an object travels through in a certain amount of time. The angular speed will measure in units of radians per second i.e. radian per second.
What Is The Difference Between Speed And Linear Speed?
The angular speed is the rate at which the thing turns, described in units like revolutions per minute, degrees per second, radians per hour, etc. The linear speed is the speed at which a a point on the edge of the object travels in its circular path around the center of the object.
How Do You Calculate Linear Speed?
Given a complete circle, it has 2π radians. At a distance of r, or radius, from the rotation’s centre. The linear speed of a point on the object is thus equal to the angular speed multiplied by the distance r. Meters per second and meters per second is the unit of measurement.
Why Don’t We Feel The Earth Spinning?
But, for the most part, we don’t feel the Earth itself spinning because we are held close to the Earth’s surface by gravity and the constant speed of rotation. Our planet has been spinning for billions of years and will continue to spin for billions more. This is because nothing in space is stopping us.
What Are The Four Types Of Speed?
There are four types of speed and they are:
- Uniform speed.
- Variable speed.
- Average speed.
- Instantaneous speed.

In this article, you know what is the average linear speed of the earth. Earth is a very important and unique planet for humans. Because it is the only planet that supports life. It is the third-largest planet in the solar system by size and mass. While scientists continue to hunt for clues of life beyond Earth, our home planet remains the only place in the universe where we have ever identified living organisms. Earth is unique for many reasons, but it’s available water and oxygen are two defining features. This is all about the Earth and the linear speed of earth.
