In this talk I will show how to use precision data from orbital motion to constrain models of ultra-light dark matter (masses form 1E-22 eV – 1E-18 eV). I will first discuss how these dark matter candidates affect pulsar timing observations (in particular in binary systems). Then, I will describe the effect that the soliton that these models generate in the center of galaxies has on orbital motions. As I will show, these modifications can be used to rule out some of the models.
