Why Do Satellites' Orbits Look Like A Sine Wave On The ...

Dec 03, 2019· Why the ISS path appears like a wave on the map of the world? Short answer: ISS, just like any other artificial satellite, follows an (almost) circular path around Earth. The reason its orbit looks like a wave is because the orbit is 3-dimensional in nature, but when it's projected on a 2-D Mercator map of the world, it flattens and appears distorted, so it looks like a sinusoidal wave.
