Is the sky bigger than the sun

The Sun is the largest object in the Solar System and contains about 99.866% of the total mass of this system. The other 0.134% of the Solar System mass is contained mostly in Jupiter while the other seven planets contain the remaining mass. From a size perspective, the Sun is ten times larger than Jupiter and hundreds of times larger than Earth as measured by its diameter.

The Sun is described is a main sequence star because of the type of fuel it is burning. It burns hydrogen as its predominant fuel. That is, it follows a predictable life cycle where its mass and size along with its luminosity (color) varies as it ages. However, some stars do not follow this life cycle. According to the H-R diagram or Hertzsprung-Russell diagram above, our Sun is a yellow star. The Sun is yellow because it is emitting all the color photons of light at the same time, but it emits a little more of it as yellow photons. On the other hand, red stars appear red because they are emitting predominantly red photons, but they are also emitting the photons in other colors and are cooler than the Sun. They are emitting light at a longer wavelength and lower energy level.

According to the diagram, our Sun is now enjoying its middle age as far the age of the Sun is concerned. So it has a long way to go before it finally dies out. Here are nine stars that astronomers have found to be much larger and brighter than our Sun.
