C/2020 F5 (MASTER) is a non-periodic comet discovered on 28 March 2020, by the MASTER auto-detection system near San Juan, Argentina. When first discovered there were dubious claims that it might be an interstellar object, but now it is known to have a weakly near-parabolic eccentricity of just 0.99509. Before planetary perturbations the comet had an orbital period of about 36,000 years.
