Presentation transcript:

The planet orbits are slightly squashed circles (ellipses). Comets have special orbits which mean they are much closer to the Sun at some times than at others. The further away the orbiting body, the longer it takes to complete the orbit. Orbits

Planets orbiting Planets orbiting

Comets Comets

Gravity is an attractive force which acts between all objects. Gravitational force increases with; increasing mass of the body decreasing distance from the body Planets and satellites can stay in orbit because they are travelling above a certain horizontal speed Gravity
