Like perhaps not deuterium or > deuterium-tritium fusion, but proton-proton fusion??* The smallest true star, that is a star that undergoes proton-proton fusion in its core, has about 80 times the mass of Jupiter, although pseudo-stars just 20 times the mass of Jupiter can undergo deuterium-deuterium or deuterium-tritium fusion for a short time until their fuel is used up. Jupiter's mass is 319 times the mass of the Earth and the Sun has about 1050 times the mass of Jupiter.
