Almost all of the mass in our solar system is in our Sun.
99.86% of the Solar System's mass is contained within the Sun
Most of the mass of our solar system is located in the sun, which accounts for over 99% of the total mass. The remaining mass is distributed among the planets, moons, asteroids, and other celestial bodies in the solar system.
Because it has almost all of the mass in the solar system, and that's how gravity works in such a situation.
The sun has by far the most mass as any other single abject in the solar system.
99.5% of the mass of the entire solar system is in the Sun. And more than 99% of the energy generated in the solar system is also from the sun. It's the largest mass in the solar system, and it's generating almost all the solar system's power - it stands to reason it's going to be the biggest and brightest thing in the solar system.
By my own calculations Jupiter counts for around 0.097% of the mass of the Solar System. The Sun on the other hand accounts for about 99.86%. After the mass of the Sun you have 0.14% of the mass of the solar system to distribute among the planets. Of this Jupiter takes up almost 0.10%
Because it is massive: the sun accounts for almost all the mass of the whole solar system.
99% of all the mass in the Solar System is the Sun.
The mass of the sun is about 99.86% of the mass of the entire solar system.
The Sun has about 99.86% of the mass in the solar system.
Most of the mass of the solar system is in the sun. As a consequence all objects in the solar system orbit the sun.
The majority of the mass in the solar system is concentrated in the sun, accounting for about 99.86% of the total mass. The planets, including Earth, make up only a small fraction of the solar system's mass.
