Pluto
The Earth is an inner planet, and all the inner planets are rocky. The Moon is made out of the same matter as the Earth, so yes, they are both rocky spheres.
There is no planet that has the same size moon as the planet. This is only possible if Pluto was still a planet.
There not made with the same rock. It depends on the temperature of the planet
A Planet is a large body of rock and gas. Planets do not twinkle like star. A planet At Least Has One Moon A Planet Orbits The sun.. that was about planets and now moons a moon is a small rounded body hat orbit around a planet. The moon is not a planet a moon orbit a planet. Now This How They Are The Same.... Both in outer space. planets and moons both have oval shaped orbits. they Both do ot produce there own llight :) The End Im A 4th Grader I Got To Beaver Ridge Elementry :) contact questions and ill answer it!
best answer: once upon a time they were both a single planet, a major collision flung off enough material to form the moon (and to spin the remaining Earth so that we now have a 24 hour day)
No. Since the moon is not geologically active it cannot produce metamorphic rock and since it has no forces of erosion and deposition it cannot produce sedimentary rock. As a result, all the rocks on the moon are igneous
Mercury is roughly the same size, but it is bigger than our Moon.
It is a moon of the dwarf planet Pluto. They are so nearly the same size it could almost be called a double planet system
Charon.
Pluto would be the best answer, but Pluto is only a dwarf planet. Also its largest moon, Charon, is still not as big as Pluto itself.
all of them form at the same time
The weight of the rock would be less on the moon compared to Earth due to the moon's weaker gravity, but the mass of the rock would remain the same.
