Planets
v. 0.8.1 (6-16-17)
--------------------

--- To add a planet, select a mass from the scroll bar, then click and drag on the screen. The more you drag, the more velocity the planet will have. The scroll bar is logarithmic.

--- The yellow trail is the planet's motion in relation to the selected planet. The green trail signifies the planet's actual position in space.

--- Use the arrow keys to select a planet. Then you can change the name of the planet by clicking on the textbox and typing in the new name. Click anywhere else to finish.

--- Play / pause and show / hide buttons are self-explanatory, C means clear, R means remove the selected body. The theme can be changed by clicking on the lower right box.

--- The red crosshair is the barycenter of the system.

--- Upcoming features include detecting escape velocity, display more planet info, and planet simulations.

--- The way I made this was every act, the world clears the image and redraws it (No Actors).

Works on any browser if you append "?js=true" to the end of the URL! (I still need to fix font)

I am making a better version of this at nichodon.github.io/programs/0005
