The Sun holds 99.86% of the mass in our solar system, leaving the planets, moons, asteroids, and comets with only 0.14% combined. Even though Jupiter outweighs all other planets together, it still appears as a mere speck compared to the Sun. Formed about 4.6 billion years ago from a collapsing cloud of gas and dust, the increasing pressure and temperature at its core reached around 15.7 million degrees Celsius. This environment sparked nuclear fusion, powering the Sun by converting hydrogen into
