Solen er vores n\u00e6rmeste stjerne. Solen forsyner os med lys og varme. Den udsender ogs\u00e5 farligt ultraviolet lys, som for\u00e5rsager solskoldning og kan medf\u00f8re kr\u00e6ft. Uden Solen ville der ikke v\u00e6re dagslys, og vores planet ville ganske enkelt v\u00e6re en m\u00f8rk, frossen verden uden hav med flydende vand og uden liv.<\/p>\n<\/div>\n

Denne enorme kugle af gl\u00f8dende gas har en diameter p\u00e5 1,4 millioner kilometer, hvilket svarer til 109 Jorder sat side om side. Med en masse p\u00e5 2 millioner billioner billioner kilogram vejer den lige s\u00e5 meget som 330 000 Jorder. Der ville v\u00e6re plads til omkring 1 300 000 Jorder inde i Solen!<\/p>\n

Set fra Jorden ser det ud, som om Solen bev\u00e6ger sig hen over himlen om dagen og forsvinder om natten. Det skyldes, at Jorden drejer mod \u00f8st. Jorden drejer om sin egen akse, en imagin\u00e6r linje, der l\u00f8ber gennem Jordens midte mellem Nord- og Sydpolen. Det betyder, at for os her p\u00e5 den roterende Jord ser det ud, som om Solen st\u00e5r op i \u00f8st om morgenen og stiger h\u00f8jere og h\u00f8jere op p\u00e5 himlen hen imod middagstid. Om eftermiddagen ser det s\u00e5 ud, som om Solen bev\u00e6ger sig lavere og lavere ned p\u00e5 himlen, inden den g\u00e5r ned i vest.<\/p>\n

Selvom den ser lille ud ved solopgang eller solnedgang, skyldes det blot, at Solen befinder sig ca. 150 millioner km v\u00e6k fra os. P\u00e5 denne afstand tager det cirka 8 minutter for sollyset at n\u00e5 frem til os \u2013 selvom det bev\u00e6ger sig med en hastighed p\u00e5 cirka 300 000 km\/s. Det betyder, at vi ser solen g\u00e5 ned otte minutter efter, at det faktisk er sket!<\/p>","protected":false},"excerpt":{"rendered":"
