This application is probably best suited for children with parential attendance.

Using the device sensors "Fun with Planets" finds the Sun, Moon and planets of our solar system by moving the device along the sky. For this work for you, your device must incorporate an orientation sensor.

In its early weeks, the application is rolled out for free, but will be further developed for more stability, higher accuracy and further details, as it transits to a paid product.

"Fun with Planets" informs equatorial, horizontal, ecliptical and galactic coordinates of any position in the sky and centered solar system objects as well as local time and sidereal time on a single screen which also includes a compass.

Object data, such as current sky position and ephemerides are provided upon tapping on an object image.

"Fun with Planets" employs the device camera which can be toggled on and off. Most device cameras, however, are not sensitive enough to capture the planets in its preview screen. "Fun with Planets" attempts to increase the ISO value to a maximum. Unfortunately, not all devices support this function. If you prefer to use this application with engaged camera, make sure that the device battery is charged.

"Fun with Planets" is believed to run on both phones and tablets, however, not all devices are designed to the Android standard. Before you rate emotionally in a haste, please send the author an email in case of issues. Comments posted in Google Play cannot be replied.

As seen from the vantage of Earth, solar system objects are moving along an apparent path in the sky which is called "the ecliptic", which is the exact path of the sun over a year, specifically, the plane of the orbit of Earth around the sun. The orbits of the moon and the planets are slightly inclined to the ecliptic in that they do not move on, but very close to the ecliptic. In due course of Earth's orbit, the sun apparently moves through 13 constellations, from Pisces to Aquarius, that are crossed by the ecliptic. Since Earth's equator is tilted 23.4 degrees against the ecliptic, the ecliptic draws a sine-shaped curve around the equator of Earth projected on the sky.
