gibbous moon
解釋
凸月-
As it circles our planet, the changing position of the moon with respect to the sun causes our natural satellite to cycle through a series of phases : new, new crescent, first quarter, waxing gibbous, full, waning gibbous, last quarter, old crescent and back to new again
當月球進入地球的半影時,應該是半影食,但由於它的亮度減弱得很少,不易察覺,故不稱為月食,所以月食只有月全食和月偏食兩種。 -
Changed of moon phases are brough about by the non - self - luminosity and the opacity of the moon. as the moon is a spherical body, sunlight can only illuminate half of the moon. viewing from different directions, the moon will appear to take the shapes of a circle, a semi - circle, a crescent, a gibbous or even completely invisible at all when its dark side faces the earth
由於月球本身不發光,只是反射太陽光,所以當月球運轉時,月球地球和太陽三者的相對位置便會不斷變化,因此,地球上的觀測者所見到月球被照亮的部分也在不斷變化,從而產生不同的月相
