Sun: From The Start to The Death ( Full Ditels )

 Amazing Sun Facts With Full Life From The Starting to The End

The Sun (or Sol), is the star at the center of our solar system and is responsible for the Earth’s climate and weather. The Sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core.( Sun Facts)

The sun is by far the largest object in the solar system(Sun Facts). It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earth could fit inside the sun.(Sun Facts)

The visible part of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius)(Sun Facts), 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.(Sun Facts)

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.

How Was the Sun Formed? with Sun Facts

In a wide expanse of space, gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material, with the planets close behind. But how did a sea of swirling particles become the brightest star in our sky?

Although it may look empty, space is filled with gas and dust. Most of the material was hydrogen and helium, but some of it was made up of leftover remnants from the violent deaths of stars. Waves of energy traveling through space pressed clouds of such particles closer together, and gravity causes them to collapse in on themselves. As the material drew together, gravity caused it to spin. The spin caused the cloud to flatten into a disk like a pancake. In the center, the material clumped together to form a protostar that would eventually become the sun.(Sun Facts)

The young protostar was a ball of hydrogen and helium not yet powered by fusion. Over the course of about 50 million years, the temperature and pressure of the material inside increased, jumpstarting the fusion of hydrogen that drives the sun today.

The formation of the sun didn’t take up all of the clouds it was born from. What was left continued to orbit the star, while planets formed from the leftover material? The sun is an average-sized star, not too big and not too small. Its size makes it an excellent star to orbit, as it is neither large and fast-burning nor small and dim.

Several billion years from now, the hydrogen inside of the sun will run out, and the star will swell up into a red giant with a radius extending to Earth’s orbit. The helium at its core will also be consumed. The star will never be hot enough to burn the oxygen and carbon that are left behind, so the sun will fizzle out and become a white dwarf.

Just like most other stars, the sun is made up mostly of hydrogen, followed by helium. Nearly all the remaining matter consists of seven other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. For every 1 million atoms of hydrogen the sun, there are 98,000 of helium, 850 of oxygen, 360 of carbon, 120 of neon, 110 of nitrogen, 40 of magnesium, 35 of iron and 35 of silicon. Still, hydrogen is the lightest of all elements, so it only accounts for roughly 72 percent of the sun’s mass, while helium makes up about 26 percent.

Facts about Sun Facts

QUICK SUN FACTS

  1. At its center, the Sun reaches temperatures of 15 million °C.
  2. The Sun is all the colors mixed together, this appears white to our eyes.
  3. The Sun is mostly composed of hydrogen (70%) and Helium (28%).
  4. The Sun is a main-sequence G2V star (or Yellow Dwarf).
  5. The Sun is 4.6 billion years old.
  6. The Sun is 109 times wider than the Earth and 330,000 times as massive.

    DETAILED SUN FACTS

    • One million Earths could fit inside the Sun it’s too interesting Sun Facts
      If a hollow Sun was filled up with spherical Earths then around 960,000 would fit inside. On the other hand, if these Earth were squished inside with no wasted space then around 1,300,000 would fit inside. The Sun’s surface area is 11,990 times that of the Earth’s.
    • The Sun contains 99.86% of the mass in the Solar System an Amazing Sun Facts
      The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost three-quarters Hydrogen, whilst most of the remaining mass is Helium.
    • The Sun is an almost perfect sphere(Sun Facts)
      There is on 10-kilometer meter difference in its polar diameter compared to its equatorial diameter. Considering the vast expanse of the Sun, this means it is the closest thing to a perfect sphere that has been observed in nature.
    • The temperature inside the Sun can reach 15 million degrees Celsius really amazing Sun Facts
      At the Sun’s core, energy is generated by nuclear fusion, as Hydrogen converts to Helium. Because hot objects generally expand, the Sun would explode like a giant bomb if it weren’t for its enormous gravitational force. The temperature on the surface of the Sun is closer to 5,600 degrees Celsius.
    • Eventually, the Sun will consume the Earth. (Sun Facts)
      When all the Hydrogen has been burned, the Sun will continue for about 130 million more years, burning Helium, during which time it will expand to the point that it will engulf Mercury and Venus and the Earth. At this stage, it will have become a red giant
    • The Sun will one day be about the size of Earth. (Sun Facts)
      After its red giant phase, the Sun will collapse, retaining its enormous mass, but containing the approximate volume of our planet. When this happens, it will be called a white dwarf.
    • Light from the Sun takes eight minutes to reach Earth. (Sun Facts)
      With a mean average distance of 150 million kilometers from Earth and with light traveling at 300,000 kilometers per second, dividing one by the other gives us an approximate time of 500 seconds, or eight minutes and 20 seconds. Although this energy reaches Earth in a few minutes, it will already have taken millions of years to travel from the Sun’s core to its surface.
    • The Sun travels at 220 kilometers per second.(Sun Facts)
      The Sun is 24,000-26,000 light years from the galactic center and it takes the Sun 225-250 million years to complete an orbit of the center of the Milky Way.
    • The distance from the Sun to Earth changes throughout the year.(Sun Facts)
      Because the Earth travels on an elliptical orbit around the Sun, the distance between the two bodies varies from 147 to 152 million kilometers. The distance between the Earth and the Sun is called an Astronomical Unit (AU).
    • The Sun is middle-aged. (Sun Facts)
      At around 4.5 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn Hydrogen for approximately another 5 billion years. The Sun is currently a type of star known as a Yellow Dwarf
    • The Sun has a very strong magnetic field. (Sun Facts)
      Solar flares occur when magnetic energy is released by the Sun during magnetic storms, which we see as sunspots. In sunspots, the magnetic lines are twisted and they spin, much like a tornado would on Earth.
    • The Sun generates solar wind. (Sun Facts)
      This is a stream of charged particles, which travels through the Solar System at approximately 450 kilometers per second. Solar wind occurs where the magnetic field of the Sun extends into space instead of following its surface.
    • THE DEATH OF THE SUN ( Sun Facts)

    The Sun is about 4.5 billion years old. it has used up about half of its nuclear fuel (hydrogen). In about 5 billion years from now, the sun will begin to die. ( Sun Facts )
    As the Sun grows old, it will expand. As the core runs out of hydrogen and then helium, the core will contract and the outer layers will expand, cool, and become less bright. It will become a red giant star.(Sun Facts)

    After this phase, the outer layers of the Sun will continue to expand. As this happens, the core will contract; the helium atoms in the core will fuse together, forming carbon atoms and releasing energy. The core will then be stable since the carbon atoms are not further compressible. Then the outer layers of the Sun drift off into space, forming a planetary nebula (a planetary nebula has nothing to do with planets), exposing the core.(Sun Facts)

    Most of its mass will go to the nebula. The remaining Sun will cool and shrink; it will eventually be only a few thousand miles in diameter!( Sun Facts )
