Stanton Jerrold Peale (January 23, 1937 – May 14, 2015) was an American astrophysicist, planetary scientist, and Professor at the University of California, Santa Barbara.[1] His research interests include the geophysical and dynamical properties of planets and exoplanets.


Stanton J. Peale received a Ph.D. in astronomy from Cornell University in 1965, where he worked with Thomas Gold. He was an assistant professor of astronomy at UCLA before moving to UCSB in 1968.

Scientific contributions[edit]

In 1969 Peale published a generalization of Cassini's laws that explain the rotation of the Moon and other bodies subject to tides.[3]

In 1976 Peale published a procedure to determine the size and state of the core of Mercury.[4]

In 1979 Peale and collaborators predicted that Jupiter's satellite Io might show widespread volcanism as a result of the action of tides.[5] This prediction was confirmed by data from the Voyager 1 Mission which showed that Io is the most volcanically active body in the solar system.

He died on May 14, 2015 in Santa Barbara, California.[6]
