Mercury has no twin planet, it is not really like any of the other planets.
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Mars is a rocky planet. The rocky planets are Mercury, Venus, Earth and Mars. Dwarf planets like Pluto may contain rock, but also presumably much ice.
A planet's axis is the imaginary line that the planet rotates around, like spinning top.
they are alot of new planets in space that we have found. Planet X Planet Xl, Planet Neplite,Planet Planet Cel
the inner planets are terrestial and outer planet like Jupiter, Neptune etc are gas planet.
Planets orbit stars, not other planets. A planet-like object that orbits a planet is a moon.
The inner planets are like big rocks. The outer planets are like big balls of gas.
Planets are in the solar system comprising the universe. Mammals live ON a planet, like on this planet Earth.

Well, Pluto isn't recognized as a planet, but as a dwarf planet. Also, there are other dwarf planets, but they are more like really big comets than they are planets.
the planet pluto
the planets that are spotted beyond the planets are not relly planets they are like pluto small balls of rock
It can be either depending on what it's compared to. Planet is a synonym of things that are similar to planets, like satellites or moons or asteroids. Planet is an antonym of things that are opposite to planets, like black holes.
It depends on the planet. Some planets, like Jupiter, are made from gas. While others, like Earth, are rocky planets.
