  1. How hot is the sun? The Sun The Sun ▲ KS Indicator 4.3.1

  2. Characteristic: Distance from the Earth • The sun is about 93 million miles (about 150 million km) from Earth. • A car going 60 miles an hour would reach the sun in 177 years.

  3. Characteristic: Distance from the Earth • At 25, 000 miles an hour, it would take a rocket more than 5 months to cover the distance from the Earth to the sun. • Light from the sun travels 186,000 miles per second and takes 8 minutes to reach Earth.

  4. Characteristic: Temperature • The surface of the sun is about 10,000 degrees Fahrenheit (5,532 ºC or 5805 K). • The inside of the sun is about 27 million degrees (13 million ºC or 13,000,273 K).

  5. Characteristics:Temperature and Color • All things change color with heat. • Think of an example… Metal- when you heat metal, it turns red hot.

  6. A star’s color tells the temperature at its surface. Characteristics:Temperature and Color

  7. Characteristic: Brightness (apparent magnitude) • The sun is a main sequence star (middle level magnitude).

  8. Other Special Information • The sun does not belong to a constellation. • The sun is the closest star to the Earth. • The sun gives us heat and light.

  9. Other Special Information • The sun is NOT the biggest star; it is only a medium-sized star. • The largest stars are more than 1,000 times as big as the sun. • The smallest stars are even smaller than Earth.

  10. Solar Flare

  11. Solar Flare • Stream of gas shooting out from the sun.

  12. Prominence

  13. Prominence • Large cloud of gas that shoots from the sun in a arch shape.
