Recha (minor planet designation: 573 Recha) is a minor planet orbiting the Sun. It is in the asteroid belt, orbiting between Mars and Jupiter; the asteroid, discovered by German astronomer Max Wolf on September 19, 1905, was named after a character in Gotthold Ephraim Lessing's play Nathan the Wise.

Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado from 2001–2006 were used to build a light curve for this object; the asteroid displayed a rotation period of 7.15 ± 0.01 hours and a brightness variation of 0.20 ± 0.02 in magnitude.[2]

This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.[3]
