In terms of atoms, the Sun is essentially a large ball of gas composed of 91% hydrogen and 8.9% helium. When it comes to mass, the Sun is composed of 70.6% hydrogen and 27.4% helium.

The Sun has a mass 330.000 times that of our Earth, which is 5.9 quadrillion kg. Gravity holds this mass together, and it generates high pressure and temperatures at its center.

Our Sun is divided into six areas: the core, the radiative zone, the convective zone; these are the internal regions, followed by the photosphere, chromosphere, and the outer region, known as the corona.

Temperatures inside the Sun are uncontrollable, especially near its core. The core temperature of the Sun is thought to be around 27 million degrees Fahrenheit / 15 million degrees Celsius.

What is the Sun Made of


Is the Sun Getting Bigger?

The Sun is becoming larger and hotter as it continues to convert hydrogen into helium at its core. The core is collapsing as it warms up, which causes the Sun's outer layers to expand.

This is a very natural procedure that should not be feared. All stars go through this process from the moment they are created, and in the best scenario, our Sun has grown by around 20% since its formation.

Our Sun will evolve into a red giant star in the distant future. This will occur in around 5 billion years when the Sun begins its helium-burning process. When this occurs, our Sun will grow many times its current size, engulfing Mercury, Venus, and even Earth.

What Color is the Sun?

We are accustomed to thinking of our Sun as yellowish, but it is not. So, what hue is the Sun then? Our Sun, believe it or not, is white, and the bulk of photographs depicting our Sun are manipulated to seem yellow or even orange.

Scientists change these photos to make it simpler for humans to recognize our Sun. But what causes the Sun to seem yellow? It's all about the Earth's atmosphere.

Our Sun emits every hue, yet from space, it seems to be a large white ball of light. The Earth's atmosphere serves as a filter, blocking off the cold light spectrum while magnifying the warmer hues. The filtered blue light refracts from air molecules, leading to the blue hue of our sky.
