What is the Sun and why is it important?
The Sun is the star at the center of our solar system. It provides most of the light and heat that sustain Earth's climate, weather, and life.
What type of star is the Sun and how does it generate energy?
The Sun is a G-type main-sequence star (a yellow dwarf). It fuses hydrogen into helium in its core, releasing energy as light and heat.
How far is the Sun from Earth and how long does light take to reach us?
About 93 million miles (150 million kilometers) away; light takes roughly 8 minutes 20 seconds to travel from the Sun to Earth.
What are sunspots and solar flares, and how do they affect Earth?
Sunspots are cooler, magnetically active regions on the Sun's surface; solar flares are bursts of energy that can affect space weather, radio signals, and power systems on Earth when strong.
