How many times bigger is the sun compared to Earth?

Hint: The sun is the most enormous and the biggest object present in the close planetary system. However, it is often referred to as a medium-sized star among the several billions of stars in the Milky Way galaxy.

Complete answer: In the sun, hydrogen nuclei collide with one another to create helium atoms. In this process, named fusion, mass is transferred into energy. Four hydrogen nuclei are required to produce one helium nucleus, which is slightly less massive; the excess mass is transferred into energy. This tiny process occurs millions of times simultaneously meaning that the energy we receive from the sun is enough to sustain life here on earth.

The sun is almost an ideal ball. Its tropical breadth and its polar measurement contrast by just 10 km. The mean range of the sun is 696,000 kilometres, which makes its width around 1.392 million kilometres. One could arrange 109 Earths across the substance of the sun. The sun's boundary is around 4,366,813 kilometres.

Galileo was the first person in 19611 who reported seeing sunspots on the surface of the sun. These are minor regions or spots where the temperature of a small region of the photosphere is particularly cooler than its overall surroundings. The bright white disk that appears in the sky is the layer of the sun called the photosphere. The size of the earth is similar to that of the size of an average sunspot.

Note: The Sun weighs 333,000 times more than the amount of the earth. The sun comprises 75 percent of hydrogen, 23 percent of helium and the remaining 2 percent consists of trace amounts of other elements. The estimated age of the sun is 4.603 billion years.
