(34403) Sessin Main-belt Asteroid
Discovered on 2 September 2000 by LONEOS at Anderson Mesa.
Wagner Sessin (1946–1997) was a Brazilian dynamicist at the Instituto Tecnológico de Aeronáutica, Brazil. He is known for developing a transformation to reduce a resonant three body problem with low eccentricity orbits into an integrable model, which has applications to asteroids.Naming citation (WGSBN Bull. 3, #9, 33), IAU / Minor Planet Center, via NASA/JPL
