Learning outcomesSuccess criteria Understand the place of the Earth in the Universe in terms of how big the Universe is. 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
