- Planets reflect sunlight and Orbit the sun in Ellipses.
- The Solar System
- Stars and planets are very different to each other.
- Planets are much smaller and just reflect light.
- Planets are much much closer to us than any stars (except the sun)
- Stars and planets are very different to each other.
- Eight planets orbit the sun in almost circular paths (Ellipses).
- Closest planets to the sun are inner planets.
- Mercury, Venus, Earth And Mars.
- Planets often have moons orbiting them, they ten to be much smaller and close to their planet.
- Jupiter, Saturn Uranus and Neptune.
- Planets often have moons orbiting them, they ten to be much smaller and close to their planet.
- Mercury, Venus, Earth And Mars.
- Outer planets are much further away.
- Jupiter, Saturn Uranus and Neptune.
- Asteroid belts
- Comets, dwarf planets (pluto) and dust all orbit the sun.

- You can see some planets with the naked eye.
- They look like stars, but they're totally different.
- Stars and planets are very different to each other.
- Planets are much smaller and just reflect light.
- Planets are much much closer to us than any stars (except the sun)
- The sun's diameter is over 100 times bigger than the Earth's.
- Stars are huge, very hot and far away.
- They give of lots of light which is why you can see them from far away.
- Stars are huge, very hot and far away.
- The solar system is about 5 thousand million years old.
- 1) It was formed over a very long period from big clouds of dust and gas.
- 2) One cloud started to get squeezed slightly from perhaps a nearby star exploding.
- 3) Gravity started to take over after the particles started to move closer to each other.
- 4) Gravity pulled things together until the whole cloud started to collapse in on itself.
- The Solar System
- 5) At the centre of the collapse, particulates came together to form a protostar.
- 6) When the temp got hot enough, fusion started.
- 7) Hydrogen nuclei joined together to make helium.
- 8) Fusion gives heat and light, so a star (our sun) was born.
- 9) The energy of the sun and other stars come from hydrogen nuclei.
- 10) Chemical elements in clouds of heavier atoms than helium and hydrogen are also formed in the stars by fusion of different nuclei.
- 11) Planets are made of hydrogen, helium and heavier elements clumping together.
- 12) Oldest rocks on Earth are meteorites.
- Comets are balls of rock, dust and ice which orbit orbit the sun in elongated ellipses.
- Asteroids and comets are smaller than most planets.
- Asteroids and Comets are made of left over stuff from the formation of the solar system.
- Asteroids are smallish lumps of rubble and rock.
- The ice from a comet melts it gets closer to the sun.
- This leaves a bright tail of gas and debris, that can be see from Earth.
- Asteroids and comets are smaller than most planets.
