The Sun

The Sun

The sun is a vast, glowing sphere of hot plasma at the center of our solar system. It is the primary source of energy that powers life on Earth and drives the planet's climate and weather patterns.

Size

1

Immense Scale

The Sun is an enormous celestial body, with a diameter of approximately 1.39 million kilometres, making it 109 times wider than the Earth.

2

Dwarfing the Planets

Compared to the planets in our solar system, the Sun's size is truly remarkable. It is 330,000 times more massive than the Earth.

3

Vast Gravitational Pull

The Sun's immense gravitational force keeps the planets, including Earth, in orbit around it, ensuring the stability of our solar system.

Chemical Composition

The sun is primarily composed of hydrogen and helium gases. Hydrogen makes up approximately 75% of the sun's mass, while helium accounts for around 23%. The remaining 2% consists of trace elements such as oxygen, carbon, neon, iron, silicon, and magnesium. These elements are present in the sun's core, radiative zone, and atmosphere, contributing to its diverse and dynamic nature.

Density

1.4

Density of Sun

The sun has an average density of 1.4 grams per cubic centimeter, making it one of the densest objects in the solar system.

5.5

Times Denser than Water

The sun's density is around 5.5 times greater than the density of water, due to the immense gravitational force at its core.

Temperature of the Sun

The surface of the Sun has an average temperature of around 5,500°C (9,900°F), making it one of the hottest objects in the solar system. This extreme heat is generated by nuclear fusion reactions deep within the Sun's core, where temperatures can reach over 15 million degrees Celsius.

Further from the core, in the Sun's outer layers, temperatures gradually decrease. However, the Sun's atmosphere, known as the corona, is even hotter, reaching millions of degrees Celsius due to the Sun's intense magnetic activity.
