The gas giant planets Uranus and Neptune.
One of the discoveries that led to the modern view of the Solar System was that the "orbits" of the planets were ellipses.
Ellipses
The orbits of the planets all lie in nearly the same plane for preservation of angular momentum.
to explain the motion of planets, especially the phenomenon of retrograde motion where planets appear to temporarily reverse their direction of motion. Ref: Andrew Liddle "An Introduction to modern Cosmology".
Johannes Kepler whose new theory was published in 1609.
The ancient Greeks used Ptolemy's theory, based on circles, that was good enough for the accuracy needed at the time. Later Kepler in the 16th century discovered that an ellipse is a better model of a planetary orbit. In modern times it has been discovered that an ellipse is an approximation and that true orbits have no simple description. But the ellipse is a good enough model for many purposes.

It is the heliocentric model.The planets, asteroids, comets and other bodies in the outer solar system orbit around the sun. Strictly speaking, they revolve in an elliptic orbit where the centre of mass of the sun and the orbiting body is at one of the foci of the ellipse. But the sun is much more massive than the other bodies in the solar system that the centre of mass is near enough the sun.The satellites, including ring particles, of the planets orbit their planets in a similar fashion.

I don't think there is such a thing. Our modern concept of energy evolved gradually over time; no single person can be credited for discovering it.

Galileo Galilei. He is the father of modern science and he is known for discovering the four largest moons of Jupiter named Callisto, Europa, Ganymede, and Io.
