The Solar System
The planets and other objects in the solar system stay in their orbits due to the mutual gravitational attraction between each orbiting object and the Sun.
The solar system includes planets, asteroids, comets and other objects such as the" Kuiper Belt" objects.
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.

No. Planets do not have dwarf planets. A planet-sized object orbiting a larger planet is a moon. Dwarf planets orbit the sun independent of other objects.
Pluto is no longer classified as a planet, but as a new type of object called a dwarf planet. There are three planets in out solar system orbiting beyond Pluto: Haumea, Makemake, and Eris. None of these were ever classified as planets. Outside our solar system there are over 1,050 known planets orbiting other stars in the Galaxy. The total number of planets in the Galaxy is estimated to be 100 billion to 400 billion.

Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
Over 900 planets have been discovered orbiting other stars. These are called exoplanets.
A solar system comprises a star (or combination of gravity bound stars) and their orbiting planets. We think the majority of stars are solar systems an we have detected planets orbiting stars other than the Sun. However in the process of forming a solar system we believe that planets my be permanently ejected from orbiting their stars and flung off into interstellar space. These planets would therefore indeed be outside any solar system.
The planets and other rocky and icy junk in our Solar system are always, every second, orbiting the Sun.
No. Other stars have been found to have planets orbiting them.
