Key Stage 2
Meaning
An Orbit is the path planet takes around a star and the path a moon takes around a planet.
 |
| A Planet orbiting a Star. |
About Orbits
- An orbit is a roughly circular path, but can be stretched out into an oval shape.
- The Moon orbits the Earth. This means The Moon takes a circular path around the Earth.
- All the planets orbit The Sun. This means the planets take a circular path around The Sun.
Key Stage 3
Meaning
An Orbit is the path an asteroid, comet, planet or dwarf planet takes around a star and the path a moon takes around a planet.
About Orbits
- Moons orbit planets and planets orbit the stars due to gravity.
- Newton was the first person to realise that objects were held in orbit by gravity which he explained in his Universal Theory of Gravitation.
- Gravity is a constant force directed to the centre of a massive object.
- The Moon feels a force pulling it towards the centre of the Earth. The Earth feels a force equal in magnitude but opposite in direction to that of The Moon.
|
| The planets are pulled towards The Sun by gravity. |
Key Stage 4
Meaning
An orbit is the circular or elliptical path that an object takes a more massive object due to a force of attraction acting between them.
