The Sun is the most prominent feature in our Solar System. It is the largest
object and contains approximately 98% of the total solar system mass. One
hundred and nine Earths would be required to fit across the Sun's disk, and its
interior could hold over 1.3 million Earths. The Sun's outer visible layer is
called the photosphere and has a temperature of 6,000°C (11,000°F). This layer
has a mottled appearance due to the turbulent eruptions of energy at the
surface... Want to have a look now? Download this screensaver and see the
