Soarele este steaua cea mai apropiat\u0103 de noi. Soarele ne ofer\u0103 lumin\u0103 \u0219i c\u0103ldur\u0103. De asemenea, emite radia\u021bii ultraviolete periculoase, care provoac\u0103 arsuri solare \u0219i pot duce la apari\u021bia cancerului. F\u0103r\u0103 Soare, nu ar exista lumin\u0103 natural\u0103, iar planeta noastr\u0103 ar fi pur \u0219i simplu o lume \u00eentunecat\u0103 \u0219i \u00eenghe\u021bat\u0103, f\u0103r\u0103 oceane de ap\u0103 \u00een stare lichid\u0103 \u0219i f\u0103r\u0103 via\u021b\u0103.<\/p>\n<\/div>\n

Aceast\u0103 imens\u0103 sfer\u0103 de gaz extrem de fierbinte are un diametru de 1,4 milioane de kilometri, echivalentul a 109 P\u0103m\u00e2nturi a\u0219ezate unul l\u00e2ng\u0103 altul. Cu o mas\u0103 de 2 milioane de trilioane de trilioane de kilograme, c\u00e2nt\u0103re\u0219te c\u00e2t 330 000 de P\u0103m\u00e2nturi. \u00cen interiorul Soarelui ar \u00eenc\u0103pea aproximativ 1 300 000 de P\u0103m\u00e2nturi!<\/p>\n

From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles. This means that to us here on the spinning Earth, the Sun appears to rise in the east in the morning, and climb higher and higher in the sky towards midday. In the afternoon the Sun then seems to move lower and lower in the sky before setting in the west.<\/p>\n

Although it seems small when seen at sunrise or sunset, this is only because the Sun lies about 150 million km away from us. At this distance, it takes about 8 minutes for sunlight to reach us \u2013 even when it is travelling at about 300 000 km\/s. This means that we see the Sun set eight minutes after the event has actually taken place!<\/p>","protected":false},"excerpt":{"rendered":"

The Sun is our nearest star. The Sun provides us with light and heat. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer.
