But even with those giants hogging all that mass, the Sun contains This picture compares the sizes of the Sun and the planets. On the right of the screen is more options, you can zoom in and out of the object you click on for a closer view.

You also have the option to read more about the object by clicking the "i" which will take you to a summary about the object. How to use: Click on the image to go to the menu section. The available scenarios are in fact collections of numbers that describe celestial bodies and their position. These numbers are coming, for the most part, from Nasa's websites. Their accuracy is quite impressive, more than enough for the context of this simulation. The picture that you see on any given date represents what the real Solar System looked like on that date.

The orbital elements of the planets are used to calculate their original position when picking a date. These calculations produce a very good approximation of the positions : you can compare the stars and constellations that you see in the background from other sources, provided that you place the point of view on The Earth. Some scenarios are set to be animated by calculating positions from the orbital elements, but in some cases the velocity of each planet is derived from these calculations so that the positions are no longer calculated from the elements, but from the gravity that is acting between the different bodies.

The calculation of these forces is also an approximation using a Quadratic integration, and its precision decays over time. This decay is more pronounced in some scenarios. You can find on the internet the dates of celestial events, for example eclipses or lunar phases, and check if you can observe them in this simulation.
