This applet allows you to explore the relationship between your height above the Earth and the distance you can see to the horizon.
Based on the height, the distance to the horizon will be automatically calculated. Note that the distance to the horizon is given in miles. Also note that the image is not drawn to scale.
The peak of Mount Everest, the tallest mountain on Earth, occurs 29,035 feet above sea level. (The mountain shown in the applet represents Mount Everest.) If you were standing at the summit of Everest, how many miles would you be able to see to the horizon?
Most of us will never get to the top of Mount Everest. But it might be interesting to know how far you can see to the horizon from other heights. How many miles could you see to the horizon from…
Can you find a rule that will allow you to predict the distance d to the horizon (in miles), if you know your height h (in feet) above sea level?
