南回归线[Tropic of Capricorn] [2005-8-25]
iamet 发表在 ¤〖天文〗
| | The latitude of the winter solstice (in the northern hemisphere), -23° 27', so named because the constellation corresponding to this position in the sky was Capricorn when the constellations were named nearly 2000 years ago. However, precession has resulted in a shift of the position of the Sun so that it is now in the constellation Sagittarius on the winter solstice. |
