The Sun is the [[Star|star]] at the center of our solar system and the main energy source for life on Earth.

Its core fusion powers sunlight and constantly emits particles, including [[Neutrinos]].

The Sun's higher-energy light (especially UV) is also what creates the [[Ionosphere]] on Earth.

From a cosmic perspective it is one normal star among many, but for us it is everything.
