Nuclear Fusion In the Sun - Solar System Series

The video explains the Sun's massive gravitational field, which keeps planets in orbit. It delves into nuclear fusion, a process occurring in stars' cores under extreme pressure and heat, where hydrogen nuclei fuse to form helium, releasing vast energy. This energy sustains life on Earth. The Sun's fusion reactions are self-sustaining, and with over 92% hydrogen, it can continue for another 5 billion years.
