(46514) Lasswitz is an asteroid of the inner main belt that was discovered on May 15, 1977 by the German astronomer Hans-Emil Schuster at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
Mean distance from the Sun ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Phocaea family, a group of asteroids named after (25) Phocaea . The 4: 1 orbital resonance with the planet Jupiter is characteristic of this group . The solar orbit of (46514) Lasswitz is steeply inclined at more than 23 ° to the ecliptic of the solar system , which is characteristic of Phocaea asteroids.
(46514) Lasswitz was named on April 7, 2005 after the German philosopher and writer Kurd Laßwitz . As early as 1976, a Mars crater was named after Kurd Laßwitz: Mars crater Lasswitz .
