diell

Diell is the Albanian term for the Sun, the star at the center of the Solar System. In astronomical terms, the Sun is a G-type main-sequence star (spectral type G2V) powered by hydrogen fusion in its core. It formed about 4.6 billion years ago from the gravitational collapse of a region within a giant molecular cloud and provides the energy that sustains life on Earth.

The Sun has a mass of about 1.989 x 10^30 kilograms and a radius of about 696,340 kilometers. Its surface temperature is approximately 5,778 kelvin, producing a white-yellow light visible from Earth. It emits energy across the electromagnetic spectrum, with a total luminosity of roughly 3.846 x 10^26 watts. The Sun is composed mainly of hydrogen and helium, with heavier elements making up a small fraction of its mass.

As the primary source of illumination and heat, the Sun drives Earth's climate and weather and governs the cycles of day and night. Its gravity binds the planets and other bodies into the Solar System, and solar wind interacts with planetary magnetospheres and atmospheres.

Culturally, diell is a central element in many Albanian expressions and traditions; in daily language it denotes the Sun as a celestial object. The study of the Sun is a major subfield of solar physics and heliophysics, and its activity influences space weather that can affect satellites and power grids.
