How have the planets been named? Why are the shapes of planets and stars spherical? Why aren't they square or any other shape? Why are the inner planets rocky and the outer planets large gas giants? Does rotation of planet depends on its radius? Why don't planets have phases like the moon? Will the eight planets in our solar system ever be aligned? Could a planet orbit two suns in a figure 8 pattern? Why does Uranus not orbit anticlockwise like the rest of the planets? Does a planetary orbit depend on the sun? Why doesn't Jupiter orbit the sun? Why are most planet orbits in our solar system on relatively the same 2D plane? Why don't gas planets have gas moons? Do two planets with the same gravitational force orbiting very close to each other exist? Is it possible that moons of planets in our solar system have their own moons ? Does the gravity of the planets affect the orbit of other planets in our solar system? How come the other planets have mythological names and ours is just called Earth? Is it sad that other planets in our solar system look so lifeless? What is the difference between inner and outer planets? What keeps all the 8 planets in a planer orbit?
