Sun: The Nearest Star
... It contains approximately 98% of the total solar system mass. It is a G2 type star. 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). The core has a temperature (15,000,000° C; 27,000,000° F) and pres ...
