Every second, the Sun sends to earth 10 times more neutrinos than the number of people on earth.
During nuclear fusion in the core, two types of energy are released: photons and neutrinos. These particles carry and emit the light, heat, and energy of the sun. Photons are the smallest particle of light and other forms of electromagnetic radiation. Neutrinos are more difficult to detect, and only account for about two percent of the sun’s total energy. The sun emits both photons and neutrinos in all directions, all the time.
Neutrinos are abundant subatomic particles that are famous for passing through anything and everything, only very rarely interacting with matter. About 100 trillion neutrinos pass through your body every second.
