• ENCYCLOPEDIA ENCARTA

The Milky Way Galaxy contains about 100 billion stars. All of these stars, and the gas and dust between them, are rotating about a galactic center.

Then Sun is located in the outer part of the galaxy, at a distance of 2.7 × 1017 km (1.7 × 1017 mi) from the center. The Sun, which is moving around the center at a velocity of 220 km/s (140 mi/s), takes 250 million years to complete one trip around the center of the galaxy. The Sun has circled the galaxy more than 18 times during its 4.6-billion-year lifetime.

The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so.

The Sun is destined to perish as a white dwarf.
