(511) Davida is an asteroid of the main outer asteroid belt discovered by Raymond Smith Dugan on May 30, 1903 . The asteroid is named after the American astronomer David Peck Todd .

Davida moves at a distance of 2.58 ( perihelion ) to 3.76 ( aphelion ) astronomical units around the sun in 5.638 years . The orbit is inclined 15.94 ° to the ecliptic , the orbital eccentricity is 0.186.

With a mean diameter of around 270 km, Davida is one of the largest asteroids in the main belt. The asteroid has a dark carbonaceous surface with an albedo of 0.054. It rotates around its own axis in around 5 hours and 8 minutes.

In 2002, images of Davida at the Keck Observatory were made using adaptive optics that show an irregular body.
