Here's why:
* Earth is a sphere: The Earth is a sphere, and orbits are paths around this sphere.
* Flat maps distort: When we flatten the Earth's surface into a map, we need to distort the shape to fit it onto a flat plane. This distortion can make straight orbits appear curved or wavy.
* Mercator projection: A common map projection, the Mercator projection, stretches areas further from the equator. This makes lines of longitude appear to converge at the poles, making orbits that pass near the poles look like waves.
Imagine this:
* Draw a circle on a balloon.
* Inflate the balloon. The circle now appears to be a wave-like shape.
* This is similar to how orbits appear on a flat map.
In reality:
* Orbits are elliptical paths around the Earth, governed by the laws of gravity.
* They are not inherently wavy. The perceived wavy pattern is a result of how we represent them on flat maps.
