Solar system
A generic solar system (or planetary system) consists of at least one star and various orbiting objects (such as asteroids, comets, moons, and planets).
solar system - Student Encyclopedia (Ages 11 and up)
As the Sun rushes through space at a speed of roughly 150 miles (240 kilometers) per second, it takes many smaller objects along with it.
The Solar System
The solar system is made up of the Sun and the objects that orbit around it. These include EIGHT planets, and their satellites (moons).
Other Solar Systems
Now that we've looked at how our solar system formed, we need to ask whether we got it right. Are we correct in our theories?
Solar System
Pertinent observational constraints on the formation of the solar system include 1. The solar abundance of elements has been determined spectroscopically down to relative to H. 2. Elemental abundances in meteorites are measured.
Solar System
The Solar System consists of the Sun and the astronomical objects bound to it by gravity, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago.
Solar System
The solar system formed from a giant cloud of dust and gas. Over 99.8% of the mass ended up in the Sun, our nearest stellar neighbor.

Our Solar System consists of the sun, nine planets (and their moons), an asteroid belt, and many comets and meteors. The Sun is the center of our Solar System.
The solar system's smallest planet flits back and forth from morning sky to evening sky several times a year. It never strays far from the Sun in our sky, so it's tough to find in the glare.
Appendix 2: Solar System Extrema
Here are listed the largest, brightest and densest of the major bodies in the solar system and those with best prospects for life.

The Greeks (c200 BC) went further; they viewed the solar system as sitting in an immense vacuum surrounded by the fixed stars. But even the clever Greeks knew nothing about the underlying physics of the solar system.
If you made a "to scale" model of our solar system with the Sun of diameter 20cm, Pluto would be a dot on a piece of paper about 700 meters away.
Our own world seems pretty big to us but we are by no means the largest planet in the solar system. Jupiter has 317 times more mass than Earth and Saturn is 95 times as massive as Earth. But even with those planetary giants, the Sun contains 99.

Distance in the Solar System
The scale of the planets is tiny compared to the scale of the Solar System. The distance from Earth to the moon is 384 thousand kilometers, or 9.6 times Earth's equatorial circumference.
If we know the proportions of all the orbits in the solar system, measuring just one actual distance in kilometers gives the scale of all orbits around the Sun.
