The term minor planet is still used, but after reclassification in 2006 these are now generally referred to as dwarf planets. Dwarf planets orbit the sun, but are not satellites, that is to say that they do not orbit another planet, since then they would be classified as moons. They are big enough to hold an ellipsoid shape under their own gravity (like a squashed sphere), but have not cleared their orbit of other objects. That is to say that at the same distace out, there is a significant amount of other matter that is not part of the dwarf planet.
Earth is a major planet. It is the third planet from the Sun in our solar system and one of the four terrestrial planets.
The seventh minor planet to be discovered was Iris. Since Pluto is now considered a minor planet, that would make the seventh discovered minor planet Hebe. The Others are Ceres, Pallas, Juno, Vesta and Astraea.

Yes, Pluto is considered a minor planet due to its classification as a dwarf planet within the Kuiper Belt. It was originally identified as the ninth planet in our solar system but was reclassified in 2006.
