Our Star

Planet of Self

 

Our Sun is a yellow dwarf star 4.5 billion years old. The gravity of the Sun is the reason our solar system looks the way it is. Planets revolve around it due to the gravity of it. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and aurorae. Though it is special to us, there are billions of stars like our Sun scattered across the Milky Way galaxy. At the equator, the Sun spins once about every 25 days, but at its poles the Sun rotates once on its axis every 35 Earth days. The Sun's core is about 27 million degrees Fahrenheit. The Sun’s visible surface sometimes has dark sunspots, which are areas of intense magnetic activity that can lead to solar explosions.
