Asteroid 5154, Leonov, was discovered on October 8, 1969 by Lyudmila I. Chernykh at Nauchnyj, Ukraine. It has a period of 5 years, 150 days and is slightly less than 9 miles in diameter.
It was named for prominent Soviet-era Russian actor Yevgeny Leonov (1926-1994), who was mainly known as a character actor in comic roles.
Yevgeny Leonov
Another prominent Russian with the surname Leonov was the cosmonaut Alexei Leonov, whose career in the Soviet space program was plagued with misfortune. As the first human to perform a space walk, on the Voskhod 2 mission on March 18, 1965, Leonov was forced to release some of the air from his space suit to get back into the spacecraft; the suit had become overinflated in the vacuum of space to where he couldn't fit into the airlock. Subsequent mission assignments were repeatedly canceled due to various mishaps. He eventually returned to space as commander of the Soviet portion of the 1975 Apollo-Soyuz mission.
This seems to inform asteroid Leonov's meaning as determined by Henk Middelraad: salvaged or retrieved with difficulty.
