About Motion Planet

This application simulates the motion of celestial objects under the force of their gravity. Motion Planet computes the trajectories of the objects by implementing the fourth order Runge-Kutta numerical method. The app models our solar system based on true data obtained from NASA on January 1st 2008.

The app has the following features:

> Simulation and Graphics:
Allows the user to add celestial objects with different masses at any position he/she likes. The user can set the initial velocity of the body by flicking his/her finger on the screen.

Ability to change the time-step, thereby allowing the user to vary the accuracy and speed of the simulation.

Option to add and simulate objects in our own solar system, or to create an entirely new solar system from scratch.

Contains zooming and panning controls for the simulation view.


> Solar System Information
Users can view the following data of the Sun, the 8 planets and the Moon:
Physical characteristics : Mass, Radius, Escape velocity etc.
Orbital characteristics : Aphelion, Perihelion, Orbital perid etc.
Atmospheric data : Surface pressure and composition.

It dosn't let you pick the colors, or name. It also is pretty boring and does nothing, but waste your time. Don't get it.

Needs to include Pluto as a planet. More stars. July 2015.

Pretty cool considering the algorithms involved to simulate gravitational tide and orbital motions over time. Wouldn't take much to send our system akimbo

Needs a planetary explosion or atleast something notifying that your user-4 planet has collided and so on. Cool simulation though. Gonna check out others, thx for the start of me solar simulating ;)

First five minutes playing and I already destroyed our solar system. Crackedup. Notived though that there isn't that much variety. I think something like 'random encounters'(alien attacks, comets, etc.), maybe 'Evolution'(human/alien spaceships coming from planets, or something else), and/or 'custom universes'. I have only played this for like 10 minutes, so I might have missed a few things, but all that would be pretty awesome. Put some more variety and I might rate this a five-out-of-five

A really cool app to simulate the motion of the solar system plus the effects of newton laws of gravitation.Facts about the solar system are nice and handy

Impressive app to make studying about planets interesting.Must have for teachers or student who wanna study about planets in a easy and more fun filled way ! Upgrades and more development needed !

by O####:

Too slow. There are other sims for Android with silky smooth motion that track hundreds of objects. This is probably backseat driving but I think cleaning up the source code and organizing it for efficiency will speed it up.

It could use some tlc. Then it will be great

Concept is great and everything, but its really laggy and force closes on gs3 running cm10
