Earth: liquid water on surface, nitrogen + oxygen atmosphere (ozygen due to photosynthesis, active volcanoes, water clouds, active weather, tides, one very large moon, temperature from 70c to 50c. Mars: very thin c02 atmosphere, huge, extinct volcanoes, had liquid water on the surface in the past, lots of sub surface water, temperature from 140c to 35c, no life known, may have had life at some point in the past. 15 and 17 times the mass of earth: hydrogen, helium and methane atmosphere, mantle made of ices, no solid surface, have faint rings, the north pole of uranus faces the sun, uranus is tipped a bit on the side. Both pluto and eris travel in more elliptical orbits than any of the terrestrial or jovian planets. Dwarf planets: orbit the sun, massive enough to be spherical, have not cleared their orbit, ceres is rocky, the rest of rock and ices, none have been visited by probs.
