Our solar system



In this introductory space physics video, we’ll look at our place in the solar system and its part in the Milky Way.  The video ends with an overview has to how the geocentric (Earth-centred) model of the solar system was replaced by the heliocentric (sun-centred) model, and is an excellent example of the way in which new experimental evidence can lead to the refinement or replacement of an existing scientific model.
