Q. Sun accounts for approximately what fraction of total mass of Solar System ?
Answer: 99.86%
Notes: The sun accounts for approximately 99.86% of the total mass of the solar system. The remaining 0.14% is made up of the planets and their moons, as well as asteroids, comets, and other small bodies. The sun is an enormous, luminous ball of gas that is the dominant gravitational force in the solar system. It is made up of mostly hydrogen and helium, and is so massive that the gravitational pull of its own mass keeps it from collapsing under its own weight. The sun is the primary source of light and heat for the solar system and plays a vital role in the formation and evolution of the planets and other bodies that orbit around it.
