The Eddington limit is the maximum luminosity a star can achieve when there is balance between the outward pressure of radiation and the inward pull of gravity. For the Sun to reach its Eddington limit, its luminosity would have to increase by about 30,000 times. This limit is a theoretical concept that applies to all stars, not just specific types, and the Sun is currently far below this threshold.
