To list a few:
Similarities:
- Much like other planets, Earth was created by traveling particles in space. These particles collect and break off making large masses in space. We call these planets.
- It has some form of gravitational pull and orbit. We hear of Asteroids, meteors, meteorites, etc. falling into orbit frequently.
- Most everything in space has some elemental component. Earth has all of it, the sun is a gigantic ball of fire, Pluto is ice, and so on.
Differences:
-Earth is the only Known planet in our solar system capable of sustaining life. Other planets lack an atmosphere,gravity, liquid water, or vegetation to even begin such a process.
- Earth also has plate tectonics
