The fact behind the art: Stars appear to circle the pole because the Earth spins once a day. Six hours of exposure turns each one through a quarter of a circle. Polaris barely moves because it sits less than a degree from the pole. Star positions, orbits and Moon phases are calculated from real astronomical data (a professional star catalogue and NASA JPL ephemerides), the Moon and Earth come from NASA imagery, and the painted skies and planet clouds are added for detail. Printed in our cream and navy palette.\u003c\/p\u003e\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eExclusive Poster Kingz design\u003c\/li\u003e\n  \u003cli\u003eAvailable in A5, A4, A3 and A2 unframed sizes\u003c\/li\u003e\n  \u003cli\u003eAlso available framed in A5, A4 and A3, ready to hang straight out of the box\u003c\/li\u003e\n  \u003cli\u003ePrinted on premium quality paper stock\u003c\/li\u003e\n  \u003cli\u003eDesigned and printed in the UK by Poster Kingz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSee the rest of the set in our \u003ca href=\"\/collections\/space\"\u003eSpace Posters\u003c\/a\u003e collection, or browse the whole \u003ca href=\"\/collections\/puzzle-science-posters\"\u003ePuzzle \u0026amp; Science Posters\u003c\/a\u003e range.\u003c\/p\u003e","brand":"Poster Kingz","offers":[{"title":"A5 (unframed) 5.8 × 8.3 in","offer_id":58296916803966,"sku":null,"price":7.99,"currency_code":"GBP","in_stock":true},{"title":"A4 (unframed) 8.3 × 11.7 in","offer_id":58296916836734,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true},{"title":"A3 (unframed) 11.7 × 16.5 in","offer_id":58296916869502,"sku":null,"price":14.99,"currency_code":"GBP","in_stock":true},{"title":"A2 (unframed) 16.5 × 23.4 in","offer_id":58296916902270,"sku":null,"price":22.99,"currency_code":"GBP","in_stock":true},{"title":"A5 Framed","offer_id":58296916935038,"sku":null,"price":19.99,"currency_code":"GBP","in_stock":true},{"title":"A4 Framed","offer_id":58296916967806,"sku":null,"price":24.99,"currency_code":"GBP","in_stock":true},{"title":"A3 Framed","offer_id":58296917000574,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/8989\/3410\/files\/star-trails-print-polaris-night-sky-astronomy-poster-1.jpg?v=1792788673","url":"https:\/\/posterkingzuk.com\/products\/star-trails-print-polaris-night-sky-astronomy-poster","provider":"Poster Kingz","version":"1.0","type":"link"}
