- The Solar System
- Models of the solar system
- Geocentric (Earth Centred)
- Proposed by Ptolemy
- The earth is is the centre and everything else moved around it in circular orbits
- Both only had the naked eye, no telescopes
- Heliocentric (Sun Centred)
- Proposed by Nikolaus Copernicus
- The sun is in the centre and planets move around it in circular orbits
- The moon orbits the Earth
- Planets further away from the sun move slower than the ones closer
- Stars are in a fixed dome beyond Saturn
- Both only had the naked eye, no telescopes
- Galileo Galilei
- First person to use a telescop to observe the night sky
- Observed four moons orbiting Jupiter and mountains on the moon
- Supported the heliocentric model, because not everything was orbiting the Earth
- Heliocentric (Sun Centred)
- Proposed by Nikolaus Copernicus
- The sun is in the centre and planets move around it in circular orbits
- The moon orbits the Earth
- Planets further away from the sun move slower than the ones closer

- Geocentric (Earth Centred)
- Observing the universe
- Early astronomers only had observations from the naked eye
- Telescopes make it easier to see further objects because they gather more light
- Telescopes make images more magnified and brighter
- Now, waves other than light are used to observe the universe
- Telescopes
- Refracting telescope
- Both the eyepiece and objective lens are converging
- objective lens converges a distant image at a focal point
- eyepiece magnifies the image
- Reflecting telescope
- converging eyepiece, concave mirror, plane miorror
- mirror forms an image of a distant object which is then reflected towards the eyepiece lens off the plane mirror
- Refracting telescope
