Sun Facts – The Ultimate Guide to The Sun (or Sol)

The Sun is a crucial component of life on Earth. It provides energy for most living things and has been worshipped by humans since the beginning of history. The Sun’s energy is the key to life on Earth. Without it, plant growth would cease and animals wouldn’t have a source of food! But did you know that without solar power there’d be no us? The Earth is a small part of our solar system, and the sun influences all parts of it. You might be surprised to know that even though other planets in space may not have life on them, they are still influenced by the Sun.

Facts About The Sun

  • As of today, the sun accounted for 99.86% of all mass in our solar system.
  • The Sun is a giant ball of light that emits every color and appears white to our eyes.
  • You could fit over one million Earths inside the Sun.
  • The Sun will eventually consume the Earth.
  • The energy of the Sun is created by nuclear fusion.
  • The Sun is composed of hydrogen (70%) and Helium (28%).
  • The Sun is so round, it’s almost like a perfect sphere.
  • The Sun is traveling at a blazing 220 km per second.
  • The Sun will eventually be about the size of Earth, but it’ll take billions and billions of years.
  • It takes eight minutes for light to reach Earth from the Sun.
  • The Sun is halfway through its life, but don’t worry! It’s not going to die anytime soon.
  • The distance between Earth and the Sun changes every day.
  • The sun rotates in the opposite direction to earth, making it appear as if it’s spinning clockwise.
  • The Sun rotates faster around the equator because there is less gravity at its center.
  • The Sun has a powerful magnetic field.
  • The fiery heat inside the sun can reach up to 15 million degrees Celsius.
  • Solar winds are generated by the Sun.
  • The Sun is a beautiful yellow, dwarf star.

Sun size compared to Earth, Neptune, Uranus, Saturn, and Jupiter

The Sun is much larger than the average red dwarf. In contrast, when comparing it to other types of stars such as a red giant or supergiant, we see that our sun is not very big. As such, the Sun is not the biggest type of star in space; however, it’s still larger than most.

You might think that the Sun is kind of puny in comparison to some other bodies found in our solar system. But it’s really not! The sun alone contains 99.8% of all the mass contained within this little bubble we call a ‘Solar System.’

The Sun is a massive ball of gas that’s roughly 1.4 million km (870,000 miles) in diameter, or about 110 times the size of Earth! It means more than one million earths can fit inside it.

What is the Sun?

The Sun is what scientists call a main-sequence star! This means it’s made of two gases: hydrogen and helium. Under certain conditions, the gas molecules inside stars heat up to form plasma. 

The first qualification of a neutron star is the mass that falls within a certain range, but this range differs depending on who you ask. The accepted standard ranges from 1.4 x 1029 kg to 3x1032kg – between 75 and 150 times that of Jupiter’s own sun-sized weight. 

Nuclear fusion is the most important component of a star’s core and is the second qualification. It occurs when two or more nuclear particles fuse together to create heavier elements, which releases an enormous amount of energy and heat in short order. This process must be occurring for stars like our sun to retain their brightness over time.

What type of star is the Sun?

Though we often think of the Sun as a special force in our world, it is one small star out of countless others. In fact, this sun has an ordinary nature among stars! The Sun is classified as a G-type star, also known as a “yellow dwarf” star. These are main-sequence stars with surface temperatures between 5027°C and 5727 °C.

Astronomers have estimated that there could be over one trillion stars in the universe. It is said that our Sun has many cousins beyond it, and some estimates claim 7 billion of them are located within Milky Way alone!

Does the Sun have another name?

The Sun is the star at the center of our solar system. The ancient Romans called it Sol, meaning their deity for light and warmth from its rays which we know as sunlight. That’s where scientists get “solar system” a simple term to describe an entire universe that revolves around one central point: this big ball of gas in space!

Sun Features


Sunspots are just one of the many things happening in our Sun. They form in areas that have strong magnetic activity, which makes them cooler than other parts of the sun’s surface. It is thought that these spots happen because heat can’t transfer as easily to these regions and so they cool down faster when compared with their surroundings

Solar Flares

When magnetic fields near sunspots cross, tangle, or are reorganized, an explosion of energy can be released. Intense solar flares interfere with radio communications on Earth by emitting radiation that causes problems for satellite navigation and power grids.

The Sun’s satellites

The Solar System is home to an incredible number of objects orbiting the Sun. Unfortunately, Pluto was recently downgraded from planet status but we’ll still count it here for historical purposes!
