Illustration of different stars' internal structure based on mass. The Sun in the middle has an inner radiating zone and an outer convective zone. The radiative zone is the thickest layer of the Sun, at 0.45 solar radii. From the core out to about 0.7 solar radii, thermal radiation is the primary means of energy transfer. [74]
The core of the Sun is considered to extend from the center to about 0.2 of the solar radius (139,000 km; 86,000 mi). [1] It is the hottest part of the Sun and of the Solar System . It has a density of 150,000 kg/m 3 (150 g/cm 3 ) at the center, and a temperature of 15 million kelvins (15 million degrees Celsius; 27 million degrees Fahrenheit).

While scientists have been learning more and more about our solar system and the way things work, many of our Sun's mechanics still remain a mystery. In advance of the launch of the Parker Solar ...
The Sun is a 2017 popular science book by Leon Golub and Jay Pasachoff. It describes the current scientific understanding of the structure of the Sun and its influence on Earth's processes. The book contains numerous illustrations, as well as tips on observing the Sun and related astronomical phenomena.
In solar physics and observation, granules are convection cells in the Sun's photosphere. They are caused by currents of plasma in the Sun's convective zone , directly below the photosphere. The grainy appearance of the photosphere is produced by the tops of these convective cells; this pattern is referred to as granulation .
