Why does earth revolve in an elliptical orbit? It should be in a circular orbit.
Why does planets move in elliptical orbit why not in circular orbits?
Does the radius of elliptical orbit of planets, or satellites decrease with time? Are the orbits of each planets coplanar? Does a planetary orbit depend on the sun? How close can two or more Earth sized planets orbiting a small star come before they adversely affect each others’ orbits? Why don't planets have phases like the moon? What if the earth begin to rotate in the opposite direction of its orbit? Why doesn't Jupiter orbit the sun? Do all planets have to orbit a star? What happens when the Earth stops rotating in its orbit? Do all planets rotate east to west? How does the moon rotate around the Earth? Why does Uranus not orbit anticlockwise like the rest of the planets? Why is the orbital period of a satellite independent of its mass? Why don't planetary orbits violate the law of conservation of energy? Where does the kinetic energy Come from? How do flat earth believers explain the spherical shape of other planets and moons? Why doesn't the moon rotate on its own axis like the earth does? If the Earth is is spinning at 1,675 km/hour, then why does one rotation take so long? Could a planet orbit two suns in a figure 8 pattern? 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? If an object at the equator travels at 1040mph with earth's rotation, why does it not appear to move and stand still? For what reasons does uniform circular motion have acceleration? How can you explain Uranus's tilted orbit using Einstein's view of gravity? How do satellites stay in orbits and avoid each other? How is spacetime curved if it isn't also displaced? How does the Earth move through and curve spacetime without displacing it? Since earth is spinning and so are we at the same speed. Then why are things doesn't spin at the same rate up to the height of moon? If earth is rotating at an amazing speed, why are we not thrown out? How many times does the earth spin around on its axis (relative to the fixed stars) in one year? Does the moon rotate? Why doesn't the earth's gravity pull satellites towards it? Which direction does the earth rotate and orbit the sun?
