We wish to find the height (h) which is the drop in curvature over the distance (d) Using the circumference we find that 1 kilometer has the angle360° / 40 030 km = 0.009°. The angle (a) is then a = 0.009° * distance (d) The derived formula h = r * (1 - cos a) ...

on the Moon. Normally, the only humans in space are those on the International Space Station. The station's crew, made up of six people, is usually replaced every six months. The farthest that humans have traveled from Earth is 400,171 km, achieved during the Apollo 13 mission in 1970....
How many km are in 2.88m? If 2.5 mol of dust particles were laid end to end along the equator, how many times would they encircle the planet? Note that the circumference of the Earth at the equator is 40,076 km and a typical d ...
The Moon is one of the many natural planetary satellites of the planet Earth. The mass of the object is 73,476,730,924,573,500,000,000 kg. The equatorial circumference of the Moon is 10,917.0 km. The semi-major axis of the orbit around its planet is 384,400 km. The density of th...
The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km). The surface of the earth is divided into dry land and oceans, the dry land occupying c.57.5 million sq mi (148.9 ...
The Earth is about 7,926 miles (12,756 km) in diameter. The Earth is the fifth-largest planet in our Solar System (afterJupiter,Saturn,Uranus, andNeptune). Eratosthenes(276-194 BC) was a Greek scholar who was the first person to determine the circumference of the Earth. He compared the...
