Kilometer (km)


Kilometer (km) is a unit of measurement used in space and astronautical engineering to express distances between celestial bodies or spacecraft. One kilometer is equal to 1000 meters or approximately 0.62 miles. The use of kilometers is preferred over other units of measurement in space and astronautical engineering due to its simplicity and compatibility with the metric system. Kilometers are used to measure the distance between planets, moons, asteroids, and other celestial bodies. They are also used to express the altitude of spacecraft in orbit around these bodies or in transit between them. In addition, kilometers are used to measure the size of celestial bodies, such as the diameter of planets or the length of craters on their surfaces.
