For Earth, the arithmetic mean radius is 6,371.0088km (3,958.7613mi). More than 2,000 years ago Eratosthenes compared the position of the Suns rays in two locations to calculate the spherical size of the Earth with reasonable accuracy. The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. to the plane tangent at What is the number in scientific notation? To determine the diameter of the earth in metres first multiply the original value by 2. The red dot at the lower left corner is its center. For the Earth, the authalic radius is 6,371.0072km (3,958.7603mi). Most experts think planet Earth can support about 10 billion people, and that when our population reaches that number, it will start to decline. p The value of standard gravity corresponds to the gravity on Earth at a radius of 6,375.4 kilometres (3,961.5 mi). . View this answer. The recent Juno mission launched with the goal of examining Jupiters composition and underlying structure, the wikipedia article on the Juno spacecraft provides an a great overview of this type of process. Putting in the numbers, you have Dividing both sides by m1 gives you the acceleration due to gravity: Newton's law of gravitation gives you the acceleration due to gravity near the surface of the Earth: 9.8 meters/second 2. Given you're looking for a simple formula, this is probably the simplest way to do it, assuming that the Earth is a sphere with a circumference of 40075 km. The radius of the Earth is 6371 km. If you wish to convert a small difference of latitude or longitude into the linear distance on the surface of the earth, then the spherical earth equation would be, = = dE R cos d dN R d ,
