Sun

Traveling at the speed of light (299,792,458 meters per second), photons from the Sun embark on a 150-million-kilometer journey across space. This means we always see the Sun as it was 8 minutes ago.

Scientists estimate the temperature of Earth's solid iron-nickel inner core to be around 5,200 degrees Celsius (9,392 degrees Fahrenheit). This extreme heat is a remnant from the planet's formation and ongoing radioactive decay.

Despite its immense size, Jupiter only makes up about 0.1% of the solar system's total mass. The Sun's overwhelming mass is what generates its powerful gravitational pull, keeping all planets in orbit.

When viewed from space, the Sun emits light across the entire visible spectrum, making it appear white. Its yellow appearance from Earth is due to atmospheric scattering, which removes blue light, making it seem warmer in color.

While the surface of the sun is around 9,940 degrees Fahrenheit (5,500 degrees Celsius), lightning can reach temperatures of 50,000 degrees Fahrenheit (27,760 degrees Celsius). This intense heat causes the air to expand explosively, creating thunder.
