If the earth is as big as a coin, how big is the sun?

Not that big, right? Don't you just figure it out? Compared with the sun, the earth is really small. On this side of the sun, the earth is almost inconspicuous. More than 99% of the mass in the solar system is concentrated on the sun, which is a gaseous planet with a much smaller density than the earth, so it is certain that the sun is much larger than the earth.

The average radius of the earth is 637 1 km, and the radius of the sun is 696300 km, so the radius of the sun is 109 times that of the earth. If compared by volume, the volume of the sun is1.3000 times that of the earth.

Maybe you don't have an intuitive understanding of numbers, just go to the picture above:

The radius of the sun is 109 times that of radius of the earth. This gap is very big. For example, if the earth is a sesame seed, then the sun is as big as table tennis. If the earth is a coin, if the diameter of the earth is similar to that of a coin,

The diameter of a dollar coin is about 2.5 cm, so the sun is equivalent to a sphere with a diameter of 2.7 meters.

The earth can be said not to exist in front of the sun.

As the parent star of the solar system, the sun occupies most of the mass, and it is precisely because the mass of the sun is large enough that the nuclear fusion reaction can be ignited. The continuous nuclear fusion reaction inside the sun produces a steady stream of energy to radiate to every planet in the solar system, providing a steady stream of heat and energy supply for the life activities of all living things on earth. If there is no sun, then the earth will soon perish.

There are at least hundreds of billions of stars in the universe, and the sun is just a very humble star in the universe. Compared with other stars, the sun is insignificant. Superstars, such as Shield UY, have been found, and their diameters are estimated to be 1700 times that of the sun. If the sun stood by, it would be even smaller. Such a planet would be 185300 times that of the earth. If the earth were a coin, its diameter would be 4632 meters.
