Planetary Clock is a simple and elegant iPhone app that provides accurate positions of all the planets in the Solar System on any given day. Developed by Piotr Knapczyk, this app utilizes precise calculations to determine real-time positions of the planets.

While the app does not depict the Sun and planets to scale, it does accurately calculate other parameters such as the size of the orbit, eccentricity, shape of the orbit, and the position of the planets. These calculations are based on precise data provided by NASA.

One of the noteworthy features of Planetary Clock is that it realistically sizes the planets in relation to each other. This allows users to visualize the relative sizes of the different planets in the Solar System.

With its focus on accuracy and simplicity, Planetary Clock is a valuable tool for those interested in astronomy and planetary positions. Whether you are an amateur astronomer or simply curious about the celestial bodies in our Solar System, this app provides a convenient way to explore and understand their positions.
