The Sun and The Earth

The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth – about one million Earths could fit inside the sun.

The visible part of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius), while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according to NASA.

The Sun

The sun is one of more than 100 billion stars in the Milky Way. It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium. An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.

The chemical organization of the Sun consists of hydrogen 71%, helium 26.5% and other elements 2.5%.
It takes 8 minutes 1.66 seconds for sunlight to reach the earth.
Structure of the sun

The visible surface of the Sun is the radiant surface of the Sun, which is not radiant and is red in color.
The effect is the outer part of the Sun (which is visible only at the time of solar eclipse).
X rays are emitted from the corona and the earth is affected by this corona at the time of complete solar eclipse.
When the temperature of one part of the sun decreases compared to other parts, the tow appears as spots, which is called solar stigma. The lifespan of this spot ranges from a few hours to a few weeks. Radio communication is interrupted after the solar stigma persists for several days.
