It depends upon how you define "planets". Literally "planet" means "wanderer". This was how the ancients differentiated them from the stars.
The sun is not a planet, but a star. Orbiting the sun you have closest Mercury, then Venus. The earth is third and the closest to have a large body (which you could say is a planet) orbiting it, which is the moon.
Mars is next closest, with two small bodies orbiting Phobos and Deimos. These two bodies are irregularly shaped, and were likely orbiting the sun at one time, but now orbit Mars. I believe these names mean "Fear" and "Dread".
There is a large band of bodies orbiting next out from Mars. THere are several bodies in this band called the "Asteroid Belt" which were once considered planets. One called "Ceres" was called a planet for a while. Now it is called a "dwarf planet" and I believe it is the closest dwarf to the sun. It is roughly spherical.
Then there is Jupiter, a system unto itself. It has eight bodies in regular orbit, and 55 bodies in irregular orbits. Of the first eight, the Galileans (Io, Calisto, Europa and Ganymede) are large and well known.
There are several dwarf planets in orbit of the sun between Jupiter and Saturn, (actually in Jupiter's "Lagrange" points - about sixty degrees in front and behind Jupiter in its orbit, also known as the Trojan Asteroids).
Then there is Saturn with billions of rings (literally) and 47 bodies orbiting around it, the largest of which is called Titan. If I'm not mistaken, it is nearly unique as a secondary orbiting planet, as it has an atmosphere (methane).
Then Uranus with 27 more moons.
Neptune is the next planet orbiting the sun and it has 13 bodies orbiting around it, including Triton, which is the largest irregularly orbiting body in the solar system.
Further from the sun than Neptune, there is the newly defined Kuiper Belt. Pluto used to be in the same group as the other eight, but now is considered a dwarf planet in the Kuiper belt. There are others as well, including Sedna, Orcus, Quaoar, Varuna, Ixion, Vesta, Pallus and Hygiea. You could also consider Charon, which is in a somewhat bianary orbit with Pluto to be a minor Planet. There was also some talk of Xena, which I believe is officially named 2003 EL 61.
