what would happen to orbital distances and speed of the sun was double in mass
Confidence votes 12. If an Earth-like planet was orbiting at the same distance from its double solar mass star as the Earth is from the Sun (1 astronomical unit, written 1 AU), then the force would be double that experienced by the Earth.he force at constant distance is just proportional to the product of stellar and planetary masses. We don't know of any reason why an Earth mass planet should not form at 1 AU from a star of 2X Solar mass, though we as yet have few observational measurements of such low mass extra-solar planets.
