Skywatchers prepare for ‘supermoon’
Skywatchers are preparing for the latest "supermoon" as Earth's satellite makes its closest approach since 1948.
The UK's best chance to see it will be on Monday evening, although the Moon reaches its closest approach at 11:21 GMT when it will be 356,509 km away.
satellite /'sætəlaɪt/ n. 卫星
approach /ə'prəʊtʃ/ n. 接近，靠近，方法
To observers, it will appear about 7% larger than normal and about 15% brighter - although the human eye is barely able to discern that difference.
discern /dɪ'sɜːn/ v. 识别，辨别
Yet the Moon won't be this close again until 25 November 2034.
As the Moon traces its orbit around the Earth, we see different proportions illuminated by the Sun. Once in each orbit, our satellite is totally illuminated - a full moon.

trace /treɪs/ v. 沿着路线走
