===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 [[asteroid]]s.
 +
: Over millions of [[year]]s the [[asteroid]]s collide to form bigger and bigger [[asteroid]]s until they are so large that they have enough [[gravity]] to pull their [[matter]] in to a [[sphere|spherical]] shape and become [[Dwarf Planet|dwarf planets]].
 +
: Eventually the [[Dwarf Planet|dwarf planets]] may sweep enough [[material]] out of their [[orbit]]al path that they are considered [[planet]]s.

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

The Rocky Planets
 
 
 
 
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.
The Gas Giant Planets
 
 
 
 
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

There are 8 planets in The Solar System.

The Gas Giant Planets
 
 
 
 
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

The Rocky Planets
 
 
 
 
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.
The Gas Giant Planets
 
 
 
 
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.
