Where are we? S1 Science Planet Earth topic a self-luminous celestial body consisting of a mass of gas held together by its own gravity in which energy is generated by nuclear reactions. the sun and all the celestial bodies which orbit the sun. made up of billions of different “solar systems”. made up of billions of different galaxies. a sphere of rock and/or gas which orbits a star. a sphere of rock and/or gas which orbits a planet. Planet Galaxy Moon Solar System Star Universe Learning outcomes Understand the place of the Earth in the Universe in terms of how big the Universe is. Success criteria State how long it would take us to reach each of the following in a rocket as fast as we have ever built: Neptune Our next nearest star (after the sun) State at what speed light travels in kilometres per hour. State how long it would take us to reach each of the following travelling at the speed of light: Neptune Our next nearest star (after the sun) Explain what is meant by a “light year”. State how many light years away: Our nearest star is Andromeda is 25 000 years To get to Neptune at the speed of light 12 years Distance to Andromeda 4.2 years To get to Proxima Centauri by rocket 50 000 km/h To get to Proxima Centauri at the speed of light 2.5 million light years The speed of light 4.2 light years To get to Neptune by rocket 4 hours Distance to Proxima Centauri 10 800 000 000 km/h The fastest rocket we have ever built 25 000 years To get to Neptune at the speed of light 12 years Distance to Andromeda 4.2 years To get to Proxima Centauri by rocket 50 000 km/h To get to Proxima Centauri at the speed of light 2.5 million light years The speed of light 4.2 light years To get to Neptune by rocket 4 hours Distance to Proxima Centauri 10 800 000 000 km/h The fastest rocket we have ever built • Draw a diagram to show the relationship between: – – – – – Stars Planets Moons Galaxies The Universe Learning outcomes Understand the place of the Earth in the Universe in terms of how big the Universe is.
