Kepler’s Laws
- Each planet moves around the sun in an ellipse, with the sun at one focus.
- The radius vector from the sun to the planet sweeps out equal areas in equal intervals of time.
- The squares of the periods of any two planets are proportional to the cubes of the semimajor axes of their respective orbits: T ∝ a^3/2.

The more one seeks to rise into height and light, the more vigorously do ones roots struggle earthward, downward, into the dark, the deep — into evil.
Richard Phillips Feynman (May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.

Orbit and rotation
Venus rotation and orbit are unusual in several ways, Venus is one of just two planets that rotate from east to west.
Only Venus and Uranus have this "backwards" rotation. It completes one rotation in 243 Earth days — the longest day of any planet in our solar system, even longer than a wh...

Orbit and rotation
Mercury's highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles (47 million kilometers) and as far as 43 million miles (70 million kilometers) from the Sun. It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, fa...
