The Sun

THE SUN 🌞

𝟏. The Sun, a yellow dwarf star, is the center of our Solar System and the main source of light and heat for Earth.

𝟐. It spans about 1.39 million km in diameter—109 times Earth’s size—and makes up 99.86% of the Solar System’s mass.

𝟑. About 150 million km away (1 AU), the Sun consists of layers: the core (fusion), radiative and convective zones, photosphere (visible surface), chromosphere, and corona.

𝟒. Temperatures range from 15 million °C in the core to about 5,500 °C at the surface, and up to 3 million °C in the corona.

𝟓. The Sun’s energy comes from nuclear fusion of hydrogen into helium, and sunlight takes ~8 minutes to reach Earth.

𝟔. It drives day, night, and seasons, supports life, and causes phenomena like solar storms, sunspots, flares, eclipses, and auroras.

𝟕. About 4.6 billion years old, it has ~5 billion years left before becoming a red giant, then a white dwarf.
