I am not sure about the percentage, but most of the mass is concentrated in the Sun.
The solar system, the extra solar orbitting mass.
Most of the mass in the solar system is contained in the Sun. The sun makes up 99.85% of the total mass.
Everything with mass ... i.e. ALL the objects of the solar system.
The sun makes up 99.97% of the Solar System by mass, and gives the Solar System its name ("Sol" is the official name of The Sun).
No. The sun is part of the solar system, so it cannot be bigger than it. The mass of the sun is much larger than the mass of the rest of the objects in the solar system put together, which may be what you are referring to.
"Our solar system." The "part of our galaxy" that's in our solar system is the solar system.
No, the world is a part of the solar system
No, Sirius is not part of our solar system. The only star in our solar system is the sun.
That mainly depends on what objects you want to include. There are meteorites smaller than a grain of sand, and even individual gas molecules or subatomic particles, which can be considered part of the Solar System.
There is only one star that is part of our solar system. That is the sun. The stars we see are outside our solar system. "Solar" refers to our star. It holds the solar system together as it is through its gravity that everything orbits it, creating the solar system. So it is the key part of our solar system. That is why it is part of it.
Yes, Mars is part of our solar system.
Nope, Solar System is part of the Galaxy.
