The Sun, our closest star, plays a pivotal role in shaping our planet and sustaining life. Here are some key takeaways about the Sun:
Ordinary Star: The Sun is an ordinary star among approximately 100 billion in our galaxy, the Milky Way.
Influences on Earth: It drives weather, ocean currents, seasons, and climate. Additionally, it enables photosynthesis, making plant life possible.
Formation: About 4.5 billion years ago, the Sun emerged from a molecular cloud primarily composed of hydrogen and helium. A nearby supernova’s shockwave energized the cloud, leading to its collapse and rotation. Nuclear fusion ignited, creating the Sun, while other parts formed planets and celestial bodies.
Composition: The Sun is a blazing combination of gases, primarily hydrogen (75%) undergoing nuclear fusion to produce helium. It’s a hot ball of plasma and constitutes over 99% of the solar system’s mass.
