If there is no gravity in space, why are planets spherical?
How and why are planets spherical? What makes them round?
Neil deGrasse Tyson says the earth is pear shaped. Why do images of earth show it as round? Why don't planets have phases like the moon? Why do extraterrestrial bodies always appear as a spherical shape? Why not square or cylindrical? Why are clouds round and curved in shape? Why can't they be squares or triangles? Do spheres actually have 8 sides? Why is the earth's orbit around the sun almost circular? What is the shape of the universe, conical or spherical? What is the point of all the other planets? Why are the inner planets rocky and the outer planets large gas giants? Why do flies fly in circles? Why are most planet orbits in our solar system on relatively the same 2D plane? Why does a human heart turn spherical in space? How many spherical moons, dwarf planets and terrestrial planets are there in the Solar System? How many sides does a sphere have? Why are flying saucers round shaped? Why does a drop of water form a spherical shape on a flat surface? Why is the universe not a sphere? What are the dwarf planets in the solar system? What's the point of existence of other planets? Why do all planetary systems orbit stars? How round is the world? How many sides does a sphere have normally? Why are Newton's rings circular in shape? Why not square or any other shape? Do all planets have to orbit a star? Why are snowflakes symmetrical? How is the gravity of other planets measured? What is a planet? Why don't gas planets have gas moons? Why are solar systems and galaxies flat? What are natural satellites of a planet?
