C/2020 F5 (MASTER) is a non-periodic comet discovered on 28 March 2020,[3] by the MASTER auto-detection system near San Juan, Argentina.
When first discovered there were dubious claims that it might be an interstellar object,[4] but now it is known to have a weakly near-parabolic eccentricity of just 0.99509.[2] Before planetary perturbations the comet had an orbital period of about 36,000 years.
