SOLAR SYSTEM

Detailed explanation-1: -The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.

Detailed explanation-2: -The Sun is a star. There are lots of stars in the universe, but the Sun is the closest one to Earth, and it’s the only one in our solar system. It is the center of our solar system.

Detailed explanation-3: -The Sun is a yellow dwarf star, which means it is a medium size star. It is believed to be over 4 billion years old. The Sun spins slowly on its axis as it revolves around the galaxy. The center, or core, of the Sun is very hot. A process called “nuclear fusion” takes place there.

Detailed explanation-4: -The sun is a big ball of gas and plasma. Most of the gas 91 percent is hydrogen. It is converted into energy in the sun’s core. The energy moves outward through the interior layers, into the sun’s atmosphere, and is released into the solar system as heat and light.

Detailed explanation-5: -Like all stars, our Sun will go through several stages in its life. At the moment, it is only a middle-aged star, but like most stars, it will eventually become a white dwarf. Our hot Sun has spent the last 5 billion years turning hydrogen into helium.
