The Sun: The Basics
The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Temperature at the sun's core
About 27 million degrees Fahrenheit.
(15 million degrees Celsius)
If a human's temerature goes about 97 or 98 degrees celcius, they say you have fever. If it goes above 107 degrees to 110 degrees, the human is almost dead.

Average diameter
864,000 miles, about 109 times the size of the Earth.

Rotation period
At equator : About 27 days.
At poles : About 36 days.

Surface temperature
10,000 degrees Fahrenheit.

Composition
Hydrogen, helium.

Sun mass
The Sun is the center of our solar system and makes up 99.8 percent of the mass of the entire solar system.

Interesting facts
If the Sun were as tall as a typical front door, Earth would be about the size of a nickel.​


At the equator, the Sun spins once about every 25 days, but at its poles the Sun rotates once on its axis every 35 Earth days.

As a star, the Sun is a ball of gas (92.1 percent hydrogen and 7.8 percent helium) held together by its own gravity.
The Sun does not have any rings.

Without the Sun's intense energy, there would be no life on Earth.

But orbited by eight planets, at least five dwarf planets, tens of thousands of asteroids, and up to three trillion comets and icy bodies.

The Sun’s visible surface sometimes has dark sunspots, which are areas of intense magnetic activity that can lead to solar explosions.

The sun has an age of 4.5 billion years and is 100 million times as large as Earth. Yet it is quite a mediocre star on the universe scale. For humans, the sun is invaluable.

The sun consists of hot hydrogen and helium. At the heart of the sun huge amounts of energy are released. Even the smallest differences in the Earth's distance to the Sun mean significant temperature differences. Without the Sun the Earth would be lifeless.

Sun and Son or Grand son
Science increases age. While many do not care for their parents, some even do not see their father, grand father, father in law who has left life but is about to leave this earth.
If this human attitude & this human behaviour spreads, world will be a dangerous place. Much more dangerous than Covid19. See more information at the end of this page.
