Successive breakthroughs in the natural sciences gave rise to a system of graphical schema to represent the natural order — whether
the planetary orbits around the sun, the life cycle of plants, or the double - helix structure of DNA.

The International Astronomical Union defines «planet» as a celestial body that, within the Solar System that is in
orbit around the
Sun; has sufficient mass for its self - gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; and has cleared the neighbourhood
around its
orbit; or within another system, it is in
orbit around a star or stellar remnants; has a mass below the limiting mass for thermonuclear fusion of deuterium; and is above the minimum mass / size requirement for
planetary status in the Solar System.
Variations in how the Earth is tilted and its
orbit around the
sun make for a pattern of
planetary warming phases followed by cooling phases across the millennia.
That would make the sudden end of the last ice age a product of assuming our own independent
orbit around the
sun, and the various spikes due to
planetary interactions as the planets equalized charges and stabilized their
orbits to what we see today.
