Recha (minor planet designation: 573 Recha) is a minor planet, specifically an asteroid orbiting in the asteroid belt 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 and may have been inspired by the asteroid's provisional designation 1905 RC.

Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado from 2001 to 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.[3]
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.[4]
Between 2005 and 2022, 573 Recha has been observed to occult four stars.
