我有兴趣做一个太阳系的模拟器，让我来模拟行星和恒星的旋转和重力。

I'm interested in doing a "Solar System" simulator that will allow me to simulate the rotational and gravitational forces of planets and stars.

我希望能够说，模拟太阳系，以及跨不同的速度模拟它（即看地球和其他行星围绕太阳旋转跨天，年等）。我希望能够添加行星和行星更改质量等，来看看它是如何将影响系统。

I'd like to be able to say, simulate our solar system, and simulate it across varying speeds (ie, watch Earth and other planets rotate around the sun across days, years, etc). I'd like to be able to add planets and change planets mass, etc, to see how it would effect the system.

有没有人有会指出我朝着正确的方向写这种模拟器的任何资源？

Does anyone have any resources that would point me in the right direction for writing this sort of simulator?

有没有哪些是为此而设计的任何现有的物理引擎？

Are there any existing physics engines which are designed for this purpose?
