William Kenneth Hartmann (born June 6, 1939) is an American planetary scientist, artist, author, and writer.He was the first to convince the scientific mainstream that the Earth had once been hit by a planet sized body (), creating both the Moon and the Earth's 23.5° tilt.
Theoretical planetology, also known as theoretical planetary science [3] is a branch of planetary sciences that developed in the 20th century. [4] Scientific models supported by laboratory experiments are used to understand the formation, evolution, and internal structure of planets.
Systems with Jupiter-like planets in Jupiter-like orbits appear to be rare. There are several possibilities as to why Jupiter-like orbits are rare, including that data is lacking or the grand tack hypothesis .
Standish worked on the Jet Propulsion Laboratory Development Ephemeris.. Early versions refined the accuracy of these fundamental astronomical data-sets by including many recent and accurate observational data, new types of data, using improved data processing methods, including refined equations of motion which more accurately described the actual physics of the solar system.

According to Ney's student John E. Naugle, NASA's Associate Administrator for Space Science and Applications, one of its images was: ".... the first photograph of the night airglow taken from above." [58] NASA designated Ney's experiment as "S-1", which means that it was the first scientific experiment conducted on a crewed space flight. [59]
John S. Lewis (born June 27, 1941) is a Professor Emeritus of planetary science at the University of Arizona’s Lunar and Planetary Laboratory. His interests in the chemistry and formation of the Solar System and the economic development of space have made him a leading proponent of turning potentially hazardous near-Earth objects into attractive space resources.
