Luboš Perek

Luboš Perek (26 July 1919 – 17 September 2020) was a Czech astronomer best known for his Catalogue of Galactic Planetary Nebulae co-written in 1967 with Luboš Kohoutek. He worked on the distribution of mass in the galaxy, high-velocity stars, planetary nebulae, definition of outer space, geostationary orbit, space debris, and management of outer space.

Perek graduated from Masaryk University, Brno, in 1946, earned his PhD in Astronomy from Charles University, Prague, in 1956, and earned his DSc in Astronomy in 1961. He published 44 papers on stellar dynamics and planetary nebulae and 80 papers and articles on the geostationary orbit, definition of outer space, space debris, and protection of space environment.

The asteroid 2900 Luboš Perek, discovered by his fellow astronomer Kohoutek, was named after him. The largest telescope in the Czech Republic was also named after Perek.
