In cases where a third planet lies at the midpoint of the first two we just considered, a "planetary picture" is formed. On page 54 of the German anthology "Man: A Receiving Station of Cosmic Influences", Alfred Witte wrote: A planetary picture is formed by three planets when one of them is located at the midpoint of the other two.
在一些例子里面，当第三颗行星正好落在两颗行星的中点上时，我们认为行星的图像已经形成了，在德国人的占星学书籍里面写到"人：宇宙影响力的接收站"怀特写到当一颗行星落在另外两颗行星的中点上时，三颗行星形成了一个行星图像。

Gradually, the separate sine waves have become visible. The dominant signal, corresponding to a planet with about the same mass as Jupiter but which orbits 55 Cancri A more closely than Mercury orbits the sun, was detected in 1996. Two further sine waves emerged in 2002, corresponding to one planet that has the mass of Saturn and is also orbiting more closely than Mercury, and another with four times the mass of Jupiter that is located in what would be Jupiter's orbit.
逐渐地，&正弦波&曲线出现明显的分离。1996年，科学家探测到了起支配作用的讯号，这种讯号表明发出讯号的行星与木星有着相同的质量，但它围绕恒星&55 Cancri A&运行的距离比水星围绕太阳运行的距离还要小。2002年，另外两个&正弦波&曲线被发现，它们也分别代表两颗行星：一个行星有着土星的质量，围绕恒星的距离也比水星围绕太阳的距离要小；另一个行星有着木星质量的四倍，其位置将会预计在木星的运行轨迹上。
