The Sun holds 99.8% of all the mass in the Solar System. Every planet, every moon, every comet, every asteroid combined is less than 1%. When you drove around above, we cheated the size so you could see everything. Here is what it actually looks like.
Two things you probably never learned properly. Why is there day and night? Because Earth spins on its axis, once every 24 hours. Why are there seasons? Not because Earth moves closer or farther from the Sun. It is because Earth's axis is tilted 23.5°. When the top half tilts toward the Sun, that half has summer. When it tilts away, that half has winter. That is it. That is the whole answer.
Earth rotates on its axis. You see day when your side faces the Sun. You see night when it turns away.
The tilt never changes as Earth orbits. When your half tilts toward the Sun it's summer. When it tilts away, winter.
