There is no doubt that planets, stars, and solar systems could not ever have formed without gravity. All of these astronomical objects condensed out of clouds of interstellar gas and dust, under the influence of gravity. It is also true that planets orbit stars only because of the gravitational attraction of those stars.
It is gravity.

The center of the solar system is the Sun.
About one third of the solar systems gravity is contained in the sun.
Gravity is the force that keeps galaxies and solar systems together.

Gravity and acceleration is important to keep mass aggregates together in the Universe. Gravity structures mass aggregates into solar systems and galaxies.

Galaxies are held together by gravity. So are Solar Systems. In the case of galaxies, and galaxy clusters, it isn't entirely clear what type of masses provide this gravity - the amount of known matter is simply too small, by a factor of 5-10. For more information, do some reading on "dark matter".
That's what's responsible for their staying in orbit, and not flying off.

Greatest GravityIn our solar system, the planet with the greatest gravity is Jupiter.and lowest gravity planet is Mercury. (Pluto's gravity is lower than that of Mercury, but Pluto is no longer considered a planet.)Jupiter.

solar collectors are parts of all solar energy systems passive systems dont move pumps, fans, trackers are parts of active solar systems
Yes, for our solar system is just one of the many solar systems of the universe. In the universe, there are countless galaxies such as our Milky Way, which contain countless solar systems such as ours, that is located on an arm of the Milky Way. Solar systems are just systems of planets, asteroids, comets, etc kept in revolutions around a star from the force of gravity. There are many more stars out there besides just our star, which could just be random stars or could be big enough to create a solar system. Thus, there are many objects out there besides our own solar system. Hope this helps!
