[漢羅] 踅太陽一輾

地球踅太陽 ê 軌道 毋是圓--ê，是長株圓。 咱美麗 ê 地球 tī 長株圓軌道頂懸行到 kah 太陽上倚 彼點就叫做近日點。 遠日點就是地球 tī 長株圓軌道頂懸行到 kah 太陽上遠彼點。 今年 ê 近日點是 tī UTC 世界時 1 月 2 號 1:00，地球 kah 太陽 ê 距離差不多比伊行到遠地點 ê 距離，較近 480 萬 公里。 是講，地球 kah 太陽 ê 距離 毋是決定季節 ê 原因，嘛袂影響著日箍 ê 大細。 這張相片是攝影師 tī 德國 Heroldstatt 附近 ê 庄頭散步 ê 時陣翕--ê。 這个美麗 ê 冰日箍是一个 角寸尺 22 度，踅日頭一輾 ê 圓箍仔。 欲看著這款現象，去揣藏 tī 懸懸 ê 樹身後壁 ê 日頭，是看較會清楚。 日箍 直徑 ê 角寸尺 22 度，是浮 tī 地球大氣較懸層 ê 六角形冰晶造成--ê。

[English] Circling the Sun

Earth's orbit around the Sun is not a circle, it's an ellipse. The point along its elliptical orbit where our fair planet is closest to the Sun is called perihelion. This year, perihelion was on January 2 at 01:00 UTC, with the Earth about 3 million miles closer to the Sun than it was at aphelion (last July 6), the farthest point in its elliptical orbit. Of course, distance from the Sun doesn't determine the seasons, and it doesn't the determine size of Sun halos. Easier to see with the Sun hidden behind a tall tree trunk, this beautiful ice halo forms a 22 degree-wide circle around the Sun, recorded while strolling through the countryside near Heroldstatt, Germany. The Sun halo's 22 degree angular diameter is determined by the six-sided geometry of water ice crystals drifting high in planet Earth's atmosphere.
