This will be a one off video, basically explaining the maths behind the 'Space to Scale' videos I have previously made. How I worked out the scale for these videos has almost been the most asked question on the channel, so here is your answer! I realise it won't be everyone's cup of tea, but hopefully it will be useful to some people. Thanks to my brother - Jon - for helping out. SUBSCRIBE for more videos about our other planets.
