Why does planets move in elliptical orbit why not in circular orbits?
Why the orbits of planets are elliptical and not circular?
Does the radius of elliptical orbit of planets, or satellites decrease with time? Why is the orbital period of a satellite independent of its mass? Why don't planets have phases like the moon? How do flat earth believers explain the spherical shape of other planets and moons? Does a planetary orbit depend on the sun? Why does Uranus not orbit anticlockwise like the rest of the planets? Why doesn't Jupiter orbit the sun? Do all planets have to orbit a star? What is an orbital? What is an Orbital? How close can two or more Earth sized planets orbiting a small star come before they adversely affect each others’ orbits? Why don't planetary orbits violate the law of conservation of energy? Where does the kinetic energy Come from? How do satellites stay in orbits and avoid each other? What is meant by orbital? According to string theory, why is earth rotating around the sun on an ellipse, while gravitation field of the sun should be almost perfect circle? How can you explain Uranus's tilted orbit using Einstein's view of gravity? Does the Milky Way orbit around anything? If so, what's its orbital period? Why can't we feel the momentum of the earth's spin, nor its orbit around the sun, nor the solar system's orbit around the Milky Way's center? Why is the earth round? Can a planet have an orbit shaped like a figure 8? Could a planet orbit two suns in a figure 8 pattern? Why are clouds round and curved in shape? Why can't they be squares or triangles? What equation of motion does the Earth follow while orbiting the sun? Why so? What is meant by a geostationary orbit? What is the geostationary earth orbit? How close are the planets of our solar system to being in the same orbital plane? Why was molecular orbital theory developed? Why is it important? What is the point of all the other planets? What if the earth begin to rotate in the opposite direction of its orbit? What is the Molecular Orbital theory?
