Planetscope is a useful reference tool that calculates the positions of the 8 major planets as they orbit around the Sun, as well as the Moon's orbit around the Earth, displaying the results on 3 different views:

- Top-down 'orrery' view showing the relative locations of the planets to each other and to the Sun.

- Sky view, showing the planets locations in the sky, as viewed from your current GPS location.

- Data view, giving detailed readouts for each planet/object

The display can be speeded-up, fast-forwarding the planets' motion to help predict interesting astronomical events and to visualise various concepts about how our Solar System works.

The readings calculated for each object include Rise/Set times, Altitude/Azimuth, Right Ascension/Declination, Distances from Earth/Sun, Apparent Magnitude/Apparent Diameter, Elongation and Phase. Objects shown: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune. All readings are calculated in real-time within the program (no internet connection is required).

Planetscope是一个有用的参考工具，计算出8大行星的位置，因为它们的轨道围绕太阳，以及围绕地球的月球轨道，在3种不同的观点显示结果：

 - 自顶向下“太阳系仪”视图显示给对方，并以太阳的行星的相对位置。

 - 天空视图，显示在天空中行星的位置，因为从目前的GPS位置查看。

 - 数据视图，给出了详细的读数为每个行星/对象

该显示器可以加速的，快进行星的运动，以帮助预测有趣的天文事件和可视化了解我们的太阳系工程的各种概念。

计算每个对象的读数包括升/次，海拔高度/方位角，赤经/赤纬，距地球/太阳，视星/视直径，断裂伸长率和相位。显示对象：太阳，月亮，水星，金星，火星，木星，土星，天王星和海王星。所有的读数计算在程序中实时（无需网络连接）。
