What did the matter in the center of the solar nebula become?

The matter in the center of the solar nebula, primarily composed of hydrogen and helium, eventually formed the Sun through the process of nuclear fusion. As the nebula collapsed under its own gravity, temperatures and pressures increased, igniting fusion reactions that converted hydrogen into helium and released vast amounts of energy. This process created the Sun, which became the central gravitational anchor of the solar system, influencing the formation and evolution of surrounding planets and other celestial bodies.
