John A. O'Keefe was a prominent planetary scientist and astrogeologist at NASA from 1958 to 1995. He is known for discovering the Earth's unique third degree zonal spherical harmonic using data from the Vanguard 1 satellite, an achievement that highlighted the planet's pear-shaped gravitational field. O'Keefe also proposed the scanning microscope concept in 1956 and co-discovered the YORP effect, which explains the spinning behavior of small celestial bodies influenced by sunlight.
