Sun things to know
- The sun is a star. A star does not have a solid surface, but is a ball of gas (92.1 percent hydrogen (H2) and 7.8 percent helium (He)) held together by its own gravity.
- The sun is the center of our solar system and makes up 99.8% of the mass of the entire solar system.
- If the sun were as tall as a typical front door, Earth would be about the size of a nickel.
- Since the sun is not a solid body, different parts of the sun rotate at different rates.
- At the equator, the sun spins once about every 25 days,
- At its poles the sun rotates once on its axis every 36 Earth days.
- The solar atmosphere (a thin layer of gases) is where we see features such as sunspots and solar flares on the sun.
- The sun is orbited by
- 8 planets,
- 5 dwarf planets,
- 10.000 or more of asteroids,
- 100.000 - 3.000.000.000 comets and icy bodies.
- The sun does not have any rings.
- Without the sun's intense energy there would be no life on Earth.
- The temperature at the sun's core is about 15 million degrees Celsius (27 million degrees Fahrenheit).
