Why do planets orbit around the Sun in an elliptical pattern?
gravity is allowing the planets to achieve their escape velocity and orbit the Sun.
there is a gravitational force between the planets and the Sun, holding the planets in orbit.
gravity tilts the planets magnetic poles toward the Sun.
there is gravitational force that pushes the planet's rotation speeds beyond the Sun's rotation speed.
