The shortest distance between two places on earth
A diagram illustrating great-circle distance drawn in red between two points on a sphere, P and Q. Two antipodal points , u and v are also shown. The great-circle distance, orthodromic distance, or spherical distance is the distance along a great circle. It is the shortest distance between two points on the surface of a sphere , measured along the surface of the sphere as opposed to a straight line through the sphere's interior.
The distance between two points in Euclidean space is the length of a straight line between them, but on the sphere there are no straight lines. In spaces with curvature , straight lines are replaced by geodesics. Geodesics on the sphere are circles on the sphere whose centers coincide with the center of the sphere, and are called 'great circles'. Once two points on the surface of Earth have been identified and the Great Circle drawn through them, we can draw an angle with a vertex at the center of Earth, with its two segments intersecting the Great Circle at the two points.
The size of this angle, X, can be found from the formula where the geographic latitude and longitude of the two points are Lat1, Long1 and Lat2, Long2. Example: For Carbondale Problem 1 - The path of the August 21, total solar eclipse reaches the Pacific Coast of Oregon at latitude What is the total length of the path of the eclipse across the continental United States?
Problem 2 - An eclipse watcher from Washington, DC wants to travel to the closest spot on the East Coast where the total solar eclipse can be viewed.

How do you find the distance between a pair of points? The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance. To carry on the example: the distance between 3,2 and 7,8 is sqrt 52 , or approximately 7. What is the farthest distance on earth? Dankova in Kyrgyzstan to Hindu Tagh in China, is the longest sightline on earth at a whopping km.
Which is the shortest distance between two points? How to calculate distance between places in World? How to calculate distance between cities on Google Maps? This distance will also be displayed on google map labeled as World Distance Map. The distance between cities of World is calculated in kilometers kms , miles and nautical miles.
Distance in miles gives the mileage between cities by the World mileage calculator. What is the halfway point between two places? Find out the halfway point between two places so you can meet in the middle. Our users and editorial team have shared thousands of road trip trips. Do you have any question? Small Circles are lines that do not pass through the center of the earth. All Parallels other than the Equator are Small Circles. The distance between any two points is the length of the line segment joining the points.
There is only one line passing through two points. So, the distance between two points can be calculated by finding the length of this line segment connecting the two points. How do you calculate geodesic distance? Calculation of the Geodesic The simplest way to calculate geodesic distance is to find the angle between the two points, and multiply this by the circumference of the earth.
How do you calculate spherical distance? The haversine formula is a very accurate way of computing distances between two points on the surface of a sphere using the latitude and longitude of the two points. What is the distance between the lines 3x 4y 9? How do you find the distance between two parallel lines?
Which is the shortest distance between two points? The shortest distance between two points on the sphere is a great circle.

It could be a spiral, a slow spiral around one point and then a loop into the other. What is the distance between the two spheres? The great-circle distance, orthodromic distance, or spherical distance is the distance along a great circle.
What is the longest distance between two points? For flat surfaces, a line is indeed the shortest distance, but for spherical surfaces, like Earth, great-circle distances actually represent the true shortest distance. What is the force on the second sphere due to the first? The distance between the two spheres is 0. Therefore, the force on the second sphere due to the first is 0. How do you find the distance between a pair of points? The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance.
To carry on the example: the distance between 3,2 and 7,8 is sqrt 52 , or approximately 7. What is the farthest distance on earth? Dankova in Kyrgyzstan to Hindu Tagh in China, is the longest sightline on earth at a whopping km. Which is the shortest distance between two points? How to calculate distance between places in World?
