C/2020 F5 (MASTER) is a long period comet discovered on 28 March 2020,[1] by the MASTER auto-detection system near San Juan, Argentina. When first discovered there were dubious claims that it might be an interstellar object,[2] but now it is known to have a common weakly hyperbolic eccentricity of just 1.0007.[3] Before planetary perturbations the comet had an orbital period of about 36000 years.
