What Is The Speed Of Eclipse Shadow? 

You are here, it’s because you want to learn and know the speed of eclipse shadow. If you are a physics student, then you might have learned this topic. And this article is going to be a useful one. Do you know? During the eclipse, two shadows are formed. The first is called the umbra, which is pronounced as, UM bruh while the second shadow is called the Penumbra, which is pronounced as, pe NUM bruh. The first shadow, the umbra gets smaller as it goes away from the sun and it is the dark center of the slope shadow. Below, we will understand it in detail. Now, let’s get started and know the speed of eclipse shadow.  

What Is The Speed Of Eclipse Shadow? 

The speed of eclipse shadow is 228 miles per hour or 3683 km per hour. A solar eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth that either fully or partially blocks the Sun’s light in some areas. A solar eclipse occurs when the sun, the Earth, and the Moon line up, either fully or partially. Depending on how they align, eclipses provide a unique, exciting view of either the Sun or the Moon. 

Except for the fleeting moments of totality during a total solar eclipse, observers should always use eclipse glasses or an alternative safe solar viewing method, such as a pinhole projector, to view the Sun.   

The high-speed shadow of solar eclipse is more than 1,000 miles per hour. The speed of shadow is equal to the speed of light while the speed of solar eclipse is 2288 miles per hour. Similarly, the speed of solar eclipse shadow is 3683 km per hour. 

Now, you know what is the speed of the eclipse shadow. Let’s know how to calculate it. 

Calculate The Speed Of Eclipse Shadow 

To calculate the speed of an eclipse shadow, you need two parameters and they are distance and time. Once you get the distance and time, by using the formula you can get the speed of the eclipse shadow. The formula is given as, 

The speed of eclipse shadow =  total distance / total time 

In the symbolic form, 

V = D/T 


V – speed of eclipse shadow 

D – Distance covered 

T – total time required 

For Example,  

Let’s understand this formula with the help of an example. 

The total distance of 741 km is covered within 0.223 hours, what will be the speed of the eclipse shadow? 

So, by using the formula, 

The speed of a shadow = total distance / total time 

                                      = 741/0.223 

                                      = 3320 km/h 

About Eclipse Shadow

The eclipse shadow during a solar eclipse, the moon actually casts two shadows toward Earth. A total solar eclipse happens when the Moon passes between the Earth and the Sun, completely blocking the face of the Sun. people located in the center of the Moon’s shadow when it hits Earth will experience a total eclipse. The sky will darken as if it were dawn or dusk. 

Weather permitting, people in the path of a total solar eclipse can see the sun’s corona, which is the outer atmosphere, which is otherwise usually obscured by the bright face of the Sun. A total solar eclipse is the only type of solar eclipse where viewers can momentarily remove their eclipse glasses for a brief period of time when the moon is fully blocking the Sun.

How Fast Is The Moon Eclipse?

About One Kilometer Per Second

A total lunar eclipse occurs when the Moon travels completely into the Earth’s umbra, the dark inner portion of the shadow. The Moon’s speed through the shadow is about one kilometer per second, and the totality may last up to nearly 107 minutes.

How Fast Does A Solar Eclipse Happen?

It can take several hours for the Moon to pass in front of the Sun, but the moment of total eclipse (called totality) lasts only minutes – up to a maximum of seven minutes and 32 seconds. The period of totality varies because the apparent sizes of the Moon and Sun change depending on their distance from Earth.

What Eclipse Takes 100 Years?

Solar eclipses are fairly numerous, about 2 to 4 per year, but the area on the ground covered by totality is only about 50 miles wide. In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart.

What Is Eclipse Short Answers?

Sometimes when the Moon orbits Earth, the Moon moves between the Sun and Earth. When this happens, the Moon blocks the light of the Sun from reaching Earth. This causes an eclipse of the Sun, or a solar eclipse. During a solar eclipse, the Moon casts a shadow onto Earth.

How Rare Is A Full Eclipse?

Total solar eclipses are rare events. Although they occur somewhere on Earth every 18 months on average, it is estimated that they recur at any given place only once every 360 to 410 years, on average.


 By reading this article, you got everything about the eclipse shadow. There are mainly four types of solar eclipse and they are total solar eclipse, partial solar eclipse, annular solar eclipse, and hybrid solar eclipse. In a hybrid solar eclipse, Earth’s surface is curved, sometimes an eclipse can shift between annual and total as the Moon’s shadow moves across the globe. This is called a hybrid solar eclipse. A partial solar eclipse happens when the moon passes between the Sun and Earth but the Sun, Moon, and Earth are not perfectly lined up. This was all about the speed of eclipse shadow.
