What is the minimum required mass, expressed in solar masses ($M_{\odot}$), for an object to become a true star?

Answer

Approximately $0.08 M_{\odot}$

An object must accrete sufficient mass, equivalent to at least 0.08 times the mass of the Sun, to generate the core pressure necessary to sustain hydrogen fusion and become a main-sequence star.
