SOLAR SYSTEM

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

Detailed explanation-2: -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-3: -The temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10, 000 degrees F (5, 500 degrees C) at the surface, according to NASA (opens in new tab).

Detailed explanation-4: -The sun is made up of a blazing combination of gases. These gases are actually in the form of plasma. Plasma is a state of matter similar to gas, but with most of the particles ionized. This means the particles have an increased or reduced number of electrons.

Detailed explanation-5: -The correct answer is Sun. The sun is in the center of the solar system. It is huge and made up of extremely hot gases because of which is also called as the big ball of fire. It is mostly composed of hydrogen and helium.
