Key Stage 2
Meaning
A Planet is a large object orbiting a Star.
About Planets
- A planet is a large ball shaped object in space.
- Planets can be rocky planets or gas giants.
There are 8 planets in The Solar System.
Examples
| Mercury is the closest planet to The Sun. | Venus is the second closest planet to The Sun. | Earth is the third planet from The Sun and is the only planet known to harbour life. | Mars is the fourth planet from The Sun. It is very cold but we may send humans to live there soon. |
| Jupiter is the fifth planet from The Sun and the largest planet in The Solar System. | Saturn is the sixth planet form The Sun and has a large ring of dust and rocks orbiting it. | Uranus is the seventh planet from The Sun. | Neptune is the eighth planet from The Sun. |

Key Stage 3
Meaning
A planet is an object orbits a star which has enough gravity to become round and enough gravity to clear its orbital path of other objects.

- Planets can be rocky planets or gas giants.
There are 8 planets in The Solar System.
Examples
| Mercury is the closest planet to The Sun. | Venus is the second closest planet to The Sun. | Earth is the third planet from The Sun and is the only planet known to harbour life. | Mars is the fourth planet from The Sun. It is very cold but we may send humans to live there soon. |
| Jupiter is the fifth planet from The Sun and the largest planet in The Solar System. | Saturn is the sixth planet form The Sun and has a large ring of dust and rocks orbiting it. | Uranus is the seventh planet from The Sun. | Neptune is the eighth planet from The Sun. |
Key Stage 4
Meaning
A planet is an object orbits a star which has enough gravity to become round and enough gravity to clear its orbital path of other objects.
About Planets
- A planet is a large spherical object in orbitting a star.
- Planets can be rocky planets or gas giants.
There are 8 planets in The Solar System:
- There are thousands of exoplanets orbitting other stars in our galaxy.
Formation of the Planets
- After a nebula has collapsed to form a protostar the protostar is surrounded by a disk of gas and dust.
- Gravity causes the gas and dust clumps together to form grains, which then come to together to form asteroids.
- Over millions of years the asteroids collide to form bigger and bigger asteroids until they are so large that they have enough gravity to pull their matter in to a spherical shape and become dwarf planets.
- Eventually the dwarf planets may sweep enough material out of their orbital path that they are considered planets.
Examples
| Mercury is the closest planet to The Sun and the smallest planet in The Solar System. | Venus is the second closest planet to The Sun. | Earth is the third planet from The Sun and is the only planet known to harbour life. | Mars is the fourth planet from The Sun. It is very cold but we may send humans to live there soon. |
| Jupiter is the fifth planet from The Sun and the largest planet in The Solar System. | Saturn is the sixth planet form The Sun and has a large ring of dust and rocks orbiting it. | Uranus is the seventh planet from The Sun. | Neptune is the eighth planet from The Sun. |
