The Sun is the source of nearly all the energy that supports life on Earth. It influences Earth’s climate, weather patterns, and seasons, and provides the heat and light necessary for photosynthesis. Solar radiation affects everything from weather systems to satellite communications, and solar flares can even disrupt power grids on Earth.
In addition to its direct impact on Earth, the Sun also plays a key role in shaping the solar system’s dynamics, with its gravity holding planets in orbit. Understanding the Sun's behavior, including solar cycles and sunspots, is essential for predicting space weather and its effects on Earth.
