The mass of the sun is about 99.86% of the mass of the entire solar system.
helium
FAR less. Of all the mass in the solar system, the Sun is 99.5% of it. All the rest - Jupiter included - is one half of one percent of the solar system's mass.
Hydrogen.
The Sun's photosphere comprises 0.77% oxygen by mass but is mostly hydrogen (73.5%).
Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
The Sun 99.86%
The Sun makes up 99.8% the mass of the Solar System, not the Milky Way.
The Sun accounts for more than 99 percent of the mass of the solar system. It is a massive ball of burning gas that makes up the majority of the solar system's mass due to its immense size and gravitational pull.
Hydrogen and helium make up more than 98% of the Sun's composition. Hydrogen accounts for about 75% and helium for about 23% of the Sun's mass, with other elements like oxygen, carbon, and iron making up the remaining 2%.
The Sun contains 98.8 percent of the mass in the solar system because it is a massive ball of hot, glowing gases that make up most of the system's total mass. The Sun's gravity is strong enough to hold the planets, moons, asteroids, and other objects in orbit around it, which is why it contains the majority of the system's mass.
