The Sun is the closest star to us. It emits light and energy by virtue of the nuclear processes inside. The Sun occupies a central position in the Solar System and contains 99.9 percent of its mass. With its powerful gravity, it forces the movement of the nine planets and thousands of other smaller bodies around it.

The Sun is one of the hundreds of billions of stars that make up the Milky Way. It is about thirty light years from the center of the Galaxy, turning at a speed of 250 km / s, so it takes about two hundred and twenty-five million years to make a complete turn. It is a medium star that has reached almost half of its existence.

The Sun has a diameter equivalent to 109 times that of the Earth, a mass 330,000 times greater and a density four times smaller. Like all celestial bodies, it has a rotation movement around its own axis, but in the Sun this movement is different according to latitudes, due to the non-homogeneity of the composition of solar matter.
