The Sun is a star at the center of our solar system, essential for life on Earth.
Composed of 75% hydrogen and 24% helium, the Sun fuses these elements to produce energy.
At its core, the Sun reaches temperatures of about 15 million degrees Celsius.
The Sun's surface, known as the photosphere, is cooler at approximately 5,500 degrees Celsius.
Solar flares and coronal mass ejections are explosive events that can impact Earth's technology.
The Sun's magnetic field flips every 11 years, a phenomenon known as the solar cycle.
Sunlight takes about 8 minutes and 20 seconds to reach Earth, traveling at the speed of light.
The Sun is moving through the Milky Way at an average speed of 828,000 km/h.
In about 5 billion years, the Sun will evolve into a red giant and eventually a white dwarf.
Solar energy is the ultimate source of most renewable energy on Earth, including wind and wave power.
