This means they have the same (relative) size.\u003c\/p\u003e\u003cp\u003eThe Moon has a radius of around 1,700 kilometres and orbits Earth at an average distance of 380,000 kilometres. The Sun has a radius of approximately 700,000 kilometres and Earth orbits it at a mean distance of almost 150,000,000 kilometres.\u003c\/p\u003e\u003cp\u003eKnowing the sizes and orbits of the Sun and Earth\/Moon we can form triangles and use trigonometry and\/or intercept theorem to calculate the vanishing point, the distance from the Sun (and Moon) where both will have a (relative) physical size of zero.\u003c\/p\u003e\u003cp\u003eSurprisingly this vanishing point is not as large as one might imagine.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Andrew Robert Chapman\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798337794198\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/29\/2024\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 34\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.13lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.07d","brand":"Andrew Robert Chapman","offers":[{"title":"Paperback","offer_id":48588160073983,"sku":"9798337794198","price":9.18,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/on-the-way-to-the-andrew-robert-chapman-9798337794198","provider":"WR Book House","version":"1.0","type":"link"}
