When asteroids approach the Earth they’re at perigeon. You’ve heard of perihelion, we need a new word. We’re going to coin a word to express the concept of perihelion, but proximity to the Earth (geo), not the sun.
Perihelion is the point in the orbit of a planet, asteroid, or comet at which it is closest to the sun.– Perihelion, definition
Perigeon is the point in the orbit of a planet, asteroid, or comet at which is is closest to the Earth. It’s necessary because in the Geocentrospheric empirical cosmology the Earth is the center of the universe.
If perigeon is the functional equivalent of perihelion then, technically, we ought to find that the asteroids speed up as they approach the Earth because they’re approaching the most massive body in their orbit. This is indeed a finding: Apophis Asteroid, Nicknamed ‘God of Chaos,’ is Speeding Up.
