We have assigned names of things obviously. Planet is the name for those which goes around the sun. And satellite is the one which goes around the planet. So earth is a planet and not considered as satellite. Moon is the natural satellite to our earth.
The only planet that can't be seen from earth is earth itself. Other than earth itself other planet can be seen, however sometimes it might requires use of high technology!
Earth (Gaia) is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. There are, of course, many other names for our planet in other languages.
Earth is a planet because it makes its eay around the sun just like all the other ones do. It is a planet because it is in line with all the other planets. I hope this helped(:
