Solar system
A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.
A solar system is a group of objects that orbit around a central star, such as planets, moons, asteroids, and comets. Our solar system, for example, includes the sun and all the celestial bodies that revolve around it.
A solar system is a collection of objects that orbit a star or group of stars. In most solar systems, a central star (or stars, like a binary pair for instance) provides the mass to keep the system in place, and also the light and heat for the smaller planets, moons, asteroids, and comets that are orbiting. The Sun together with the group of celestial bodies that are held by its attraction and revolve around it, or a group of celestial bodies revolving around any star.The solar system is our planets, revolving around a solar power (sun). We kind of depend on each other.The sun and everything that orbits it ( asteriods , planets , comets , etc. )It is the biggest system which comprises of planets revolving and rotating in their orbit, where sun is at the center n other planets like Mercury, Venus, Earth, Mars etc, rotates around sun in an elliptical orbit. Till date there is only one solar system known n seen, but it is estimated that there would be many such solar system in whole universe.!!
It's called the Asteroid belt. See the related link for more informtion.
A group of planets revolving around a star is called a solar system. Each planet orbits the star in the center of the system and together they form a celestial family held together by gravity. The most well-known solar system is our own, which consists of eight planets orbiting the Sun.
The Solar System is a collection of planets, moons, comets, asteroids, and other objects that orbit the Sun. It includes eight main planets, such as Earth, Mars, and Jupiter, as well as various smaller bodies. The Solar System formed about 4.6 billion years ago from a giant cloud of gas and dust.

Personally I'd call anything that is large enough to rotate around the Sun is a planet. However, that causes "loads" of problems, orbits and mass etc. If that criteria was used we'd have hundreds/thousands of planets and sooo many problems. The current criteria makes sense and should be used. It matters not if an "object" in space is a planet, dwarf, asteroid or comet - it's nothing more than a "lump" of something orbiting the Sun.
Pluto is part of the Kuiper Belt, a ring of icy cold objects orbiting the Sun similar to the asteroid belt which starts at Neptune's orbit (around 30 times further from the Sun than Earth is) and ends around 50 times further from the Sun than Earth is. The Kuiper Belt contains millions or even billions of small frozen objects such as asteroids and comets, at least 70,000 of which are bigger than about 100km in diameter and about 200 of which are probably big enough to be considered dwarf planets, i.e. round balls of rock and ice big enough to have planet-like attributes such as internal layers, atmospheres, surface features, moons, etc. Pluto is one of the largest of these dwarf planets.And of course in the very big picture Pluto, along with all other Kuiper Belt objects, planets, moons, asteroids and comets that orbit the Sun, belongs to the Solar System, which is part of the galaxy and ultimately the Universe. Pluto is therefore part of these systems too.
inner planet
The inner planets, also known as rocky or terrestrial planets, do not have significant ring systems.
A star system is a group of stars that are gravitationally bound together. This can include multiple stars orbiting around a common center of mass, such as binary or multiple star systems, as well as planets, moons, asteroids, and other celestial objects that orbit those stars. Our solar system is an example of a star system.
