Based on a recently proposed extension to General Relativity (GR), called pseudo-complex General Relativity (pc-GR), we present a selection of several tests of GR near compact massive objects. The investigated phenomena are the redshift, the orbital frequency of a test particle and the innermost stable circular orbit (ISCO) around a massive object. We observe that the redshift and orbital frequency are in general lower in pc-GR compared to Einstein’s GR. Also the orbital frequency for prograde motion now exhibits a maximum, which is not present in GR. In addition the concept of an innermost stable circular orbit does not hold in pc-GR as it arises in GR. All modifications due to pc-GR correction terms appear only at small distances (mostly below three Schwarzschild radii) and thus can only be observed by measurements in regions of strong gravity. Those and more results have been published already in [1].
