The solar system consists of the Sun; the eight official planets, at least three "dwarf planets", more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.)
The inner solar system contains the Sun, Mercury, Venus, Earth and Mars.
The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus, and Neptune (Pluto is now classified as a dwarf planet):
The first thing to note is that the solar system is mostly empty space. The planets are very small compared to the space between them.
The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit). The ecliptic is inclined only 7 degrees from the plane of the Sun's equator. They all orbit in the same direction (counter-clockwise looking down from above the Sun's north pole); all but Venus, Uranus and Pluto also rotate in that same sense.

Good timing! When I was in school, we were taught that there were 9 planets in our Solar system (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto).
Recently a group of professional astronomers has been wrestling with new ways to define what a planet is. I don't know how many there are now (I have heard several numbers, 12 being the most frequent), but Pluto is definitely out.

DUDE.. as of now.. they have ousted Pluto from the scene and they are planning to include 3 more new planets.. 1)an asteroid between the orbits of mercury and venus by the name of Ceres i believe, 2)then another heavenly body names Xena( which is farther than Pluto) and finally 3)one of the moons of Pluto,Charon.. but i guess they will exclude Charon too now.. since pluto is no longer a planet...
So the planets will soon be.. Mercury,Ceres,Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Xena

Eight now. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

I guess there are 8 now that Pluto has been "downgraded". So that would be Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. It's hard not to say "Pluto".
