Interesting Facts About Sun: Understand Our Solar System!

The Sun has always been respected and worshiped, Over the course of the history of humanity. What our ancestors understood on a basic level was that the Sun provides a key ingredient for most of the lives on our planet.

With no energy provided through sunlight, vegetation can’t grow, and with no vegetation, animals don’t have a source of nutrition. Nonetheless, what we understand now that our ancestors didn’t is how far to reach the scope of the Sun’s influence is.

The Sun is what is known as a major sequence star; that is, a sphere composed mainly of the two gasses helium and hydrogen such that some conditions are met. The primary condition is that it must have a specific mass falling within a given range. Though the debate has been going on, this range is usually accepted to be between nearly 1.4 x 1029 kg and 3.0 x 1032 kg. (This range is usually described as at least 75 times the mass of Jupiter and less than 150 times the mass of the Sun itself)

The second and most essential condition is that nuclear fusion should always be present. Nuclear fusion is a type of process whereby two lighter atomic nuclei join or “fuse” together to produce a denser atomic nucleus. In the context of stars, helium the heavier and hydrogen is the lighter.

Both our scientific knowledge has improved and our understanding that the Earth is just a piece of the bigger structure we know as the Solar System. Also, we have found out that though other planets and celestial bodies in the Solar System may not support life, the Sun is just as influential to them.

The sunrise and sunset occur very regularly that we usually take their uniformity for granted. Even though it is so ordinary and expected in mind, in reality, the Sun is essentially the main reason for our survival as a race.

Here are interesting facts about the Sun, collected in no specific order. Some you probably know and others will be entirely new to you.




  1. The Sun is traveling at 220 kph. It is about 24,000 to 26,000 light years from the gigantic center, and it takes the Sun nearly 225 to 250 million years to complete one orbit of the center of the Milky Way.
  2. The atmosphere of the Sun comprises of three layers: the chromosphere, the photosphere, and the corona.
  3. Temperatures inside the Sun can reach almost 15 million degrees Celsius. Energy is usually produced through nuclear fusion in the core of the Sun – this is when hydrogen converts to helium – and because objects normally enlarge, the Sun would explode like a massive bomb if it were not for its terrific gravitational pull.
  4. The Sun generally rotates faster at its equator than it does near to its poles. This is referred to as differential rotation.
  5. The core of the Earth is almost as hot as the sun.
  6. The beautiful symmetry of a full solar eclipse occurs because -by a clear chance- the sun is 400 times bigger than the moon, but 400 times farther from Earth too, making the two bodies appear precisely equal size in the sky.
  7. The Sun is often thought to have completed almost 20 orbits during its lifetime and only 1/1250th of an orbit since humans’ origin.
  8. As passengers on Earth, we are all carried around the sun at an average velocity of 107,182 km/h (66,600 mph).
  9. All of the world’s energy requirements can be met with the only 1/10,000th of the light from the Sun, which falls on Earth every day, according to the inventor Ray Kurzweil.
  10. The sun has already exhausted half of its hydrogen stores. Do not worry – it still has nearly 5 billion years of hydrogen remaining to burn.
