Amazing Sun Facts | World Facts News
[ad_1]Sun is the star that is closest to us and most important. Like other stars, the Sun is a giant ball of hot gas. Without the sun, there will be no life on Earth. The sun provides heat and light for us. The sun is the closest star to Earth with an average distance of 149,680,000 km (93,026,724 miles). A spherical sun that glows with the main constituent compounds in the form of hydrogen gas (74%) and helium (25%) ionized. Nicolaus Copernicus was the first person to put forward the theory that the sun was the center of the circulation of the solar system in the 16th century. This theory was later proved by Galileo Galilei and other space observers.
The energy that makes the Sun shine is created in the center or core of the Sun. The temperature there reached 16 million degrees Celsius. In the heat that high, the hydrogen gas atoms fused, and released a very large energe.

On the surface of the Sun the temperature is around 6000 degrees Celsius. In some places, cooler and darker patches called mahari spots appear. These spots disappear and occur once every 11 years
Sometimes the Moon is between the Earth and the Sun and blocks out the sun's rays. This phenomenon is called a solar eclipse. During a total solar eclipse, we can see faint gas rings around the Sun.
- DO YOU KNOW!
- The sun is only half the length of its age, which is 5000 million years
Unique Facts of the Sun.
- The sun is a star at the center of the Solar System
- The sun is recognized as having the largest mass in our solar system.
- The diameter of the Sun is 1.4 million km (870,000 miles)
- The distance of the Sun from the Earth is 150 million km (93 million miles)
- The sun's core is composed of hot & solid gases. It has a temperature of 15 million Kelvin (27 million degrees F)
- The sun is composed of 92% hydrogen, 7% helium and the remaining various gases.
- The atmosphere of the sun consists of three fields: the photosphere, the chromosphere, and the solar corona.
- Corona is the outer atmosphere of the sun with temperatures that can go from a few thousand kelvins to several
- million kelvin.
- Earth orbits the sun for 365 days or one year.
- The sun rotates every 25-36 earth days.
- Solar energy moves outwards.
- The helmet band is a large white area extending out from the Sun where the solar plasma is trapped by the Sun's magnetic field.
- Solar flares from the sun are sudden bursts of brightness that occur in places near sunspots.
- Sunspots appear on the surface of the Sun and look dark because of the lower temperatures nearby.
- The internal structure of the Sun consists of: the inner core, radiation, the core, and the radiation core.
- The inner core is the hottest part of the Sun, and can reach 27 billion F.
- A solar eclipse occurs when the Earth passes through the Moon's shadow.
- A total solar eclipse only occurs during the new moon, which is when the moon sits directly between the Earth and the Sun.
- Solar radiation is in two forms, electromagnetic (photons) and particles (electrons, protons, alpha particles, etc.) radiation.
- In February 1974, Skylab was the first manned spacecraft to study the Sun.
- Solar flares occur when the Sun's magnetic field gathers and causes a large explosion on the surface of the Sun.
- Solar flares produce bursts of electromagnetic radiation, X-rays, ultraviolet radiation, visible light, and radio waves.
- Johann Rudolf Wolf, in 1848 developed a method for calculating sunspots that has been called the Wolf Number.
- The most ancient civilizations have based their culture on the presence of the Sun. These include myths developed by the following people: Egyptians (Re or Ra), Aztecs (Tonatiuh and Huitzilopochtli), Greeks (Helios), Incas (Inti), etc.
- If you weigh 100 lbs, your weight on the Sun will be 2707 lbs. (Multiply your actual weight by 27)
