The parallax principle can be extended to measure the distances to the stars.
视差原理可以扩展到测量地球到恒星的距离。
Knowing the width of Earth´s orbit, the parallax shift lets astronomers calculate the distance.
知道了地球轨道的宽度,视差偏移可以让天文学家计算距离。
Halley realised that Mercury was so far away that its parallax angle would be very difficult to determine.
哈雷意识到水星离地球如此之远,以至于很难确定它的视差角。
Johann Franz Encke, Director of the Berlin Observatory, finally determined a value for the AU based on all these parallax measurements: 153,340,000 km.
柏林天文台主任约翰·弗朗茨·恩克最终根据所有这些视差测量结果确定了天文单位的一个值为153,340,000公里。
As Venus was closer to the Earth, its parallax angle would be larger, and Halley worked out that by using Venus it would be possible to measure the Suns distance to 1 part in 500.
由于金星离地球更近,所以它的视差角会更大。哈雷计算出,利用金星可以测量出太阳与地球之间的距离,误差为五百分之一。
