Our Sun is responsible for keeping all the planets in our solar system in place. It ensures that Earth continues to exist and provides us with the necessary warmth. But what do we actually know about it? Do we even know its real name?

When we think of the Sun, we call it the Sun, but is there a scientific name for it? Other planets and moons have different names, so why not our Sun? These thoughts can enter your mind, and once there, are difficult to remove. We find ourselves wondering about the sun constantly, searching for questions, but never getting the answers that we need.
Well, no more! Today we are here to put your mind at ease and answer your questions. Keep reading to find out what the name of our Sun is and other interesting facts about the Sun!
What Is The Sun?
Before we dive in, let’s have a quick recap! The Sun is more than just the yellow ball in the sky that heats the Earth and lights up the sky. It is a 4.5 billion-year-old yellow dwarf star made up of hydrogen and helium.
It was formed roughly 4.6 billion years ago in a solar nebula, which is a giant spinning cloud of gas and dust. As the nebula collapsed under its own gravity, it spun and flattened into a disk. Most of the material from the nebula was pulled to the center to form the Sun as we know, while the remaining material formed the planets and objects that orbit the sun.
The helium and hydrogen in the Sun are held together by its own gravity. The Sun is made up of several regions, the interior zone includes the core, the radiative zone, and the convection zone.
Then we have the visible surface or photosphere, the chromosphere, the transition zone, and the corona, the Sun’s outer atmosphere. The SUn, as we know, is extremely hot, with a surface temperature of 10,000 degrees Fahrenheit. This extreme temperature makes it impossible for there to be life in the Sun.
The Sun has been studied greatly by scientists, with many working to learn as much as possible about the Sun and determine its lifespan. As the Sun is a dwarf star, it will eventually run out of energy.
When it does this, it will expand, becoming a red star. When it does this, it will become so large that it will engulf Mercury and Venus. It may also engulf the Earth too. Even if it doesn’t, if the Sun loses its energy, there will be nothing to hold the planets in place and the Earth would likely become uninhabitable.
Without any light or heat, it would be impossible for life to exist, plants to grow, or the seas to exist as they do now. While this is all incredibly depressing, it is a long way off! Scientists estimate that the Sun is less than halfway through its lifetime. That gives us another 5 billion years or so of the Sun before it becomes a white dwarf and loses its energy. That’s still plenty of time for us to enjoy the Sun!
Now that we have learned a little more about the Sun, let’s move on and look at its name.
What Is The Name Of Our Sun?
So what is our Sun’s name? Well, it’s a super easy one, the Sun. That’s right, there is no scientific name for the Sun, scientists refer to it as the Sun, like us all. By having just one name, it is super easy to know what scientists are talking about. While this can make it easier for everyone, the word sun is a generic name that could be used for any star.
It can also be used as a description, you could say that a star has the mass of 20 suns, or talk about planets that orbit other suns. While that could be confusing, the context of the sentence will usually give it a way that you aren’t talking about our Sun.

When we discuss our Sun we usually capitalize the ‘s’ or refer to it as our Sun or the Sun. This terminology is used in the scientific community as well as in our daily conversations.
Unlike the other stars in the sky, the Sun has no scientific name, we simply call it the Sun. At least now you know you have always been calling the Sun by its correct name!
Has The Sun Been Called Other Names Before?
Language is always changing and evolving, which means that the Sun has had some previous names. Ancient Greeks called the Sun Helios, and the word is still used today. While it was a common name for the Sun before, it was replaced during the Roman Empire with Sol.
Sol is still used to describe the Sun to this day, and as you can see, the words don’t look that different from each other written down! You will also see different names for the Sun in other languages too.
For example, in German ‘sun’ is ‘Sonne’, Spanish speakers call it ‘Dom’, and in Finnish, ‘sun’ is ‘aurinko’. You can see what other languages call the sun by checking out dictionaries or online translators. Depending on the language you speak, you might not call the Sun, sun.
But no matter the word you use for the Sun, they all mean the same thing and there is no scientific word for our Sun.
Interesting Facts About The Sun
Now that we have found out that the Sun’s name is the Sun, check out these other interesting facts before you go!
- It takes eight minutes for light to travel from the Sun and reach the Earth.
- As the Earth orbits around the Sun, the distance between the Earth and Sun changes.
- The Sun rotates in the opposite direction to the Earth, moving from west to east.
- The Sun travels at 220 km per second!
- If you hollowed out the Sun, you could fit over one million Earths inside it.
- The Sun accounts for 99.86% of the mass in our solar system.
- The Sun rotates more quickly at its equator than it does at its poles thanks to differential rotation.
- The Sun generates solar winds due to the ejection of plasma in the corona layer of the sun.
- The Aurora Borealis (Northern Lights) are caused by the interaction of solar winds with the Earth’s atmosphere.
- The Sun is almost a perfect sphere.
Final Thoughts
And there you have it, the Sun’s name is simply, the Sun. While Helios and Sol are still used, these ancient words for the Sun are far less common today than they have been. There is no scientific word for the Sun, meaning that Sun is the universal word for our Sun. Sure, there might be different ways to say it in different languages, but if you were to say ‘sun’ or ‘sol’, chances are most people would know what you are talking about!
