The journey of an Earth-like planet (blue) from Mars (red) to the Sun (yellow) -extrapolation- [Le voyage d'une planète identique à la Terre (bleue) de Mars (rouge) au Soleil (jaune) -extrapolation-].




The trajectories of the Earth (blue), Mars (red) and of the Sun (yellow) are displayed as viewed from the Sun. The plane of the Earth is rotated in order to be perpendicular to the one of Mars. During this animation, the Earth is moved from an initial position (its distance to the Sun equals the distance of Mars to the Sun) -bottom left- to the Sun -top right-. For each intermediate Earth trajectory, the 3-body system is visualized with the Sun at the origin of coordinates. Each of the displayed trajectories has a duration equals to one martian year.


Please, note that due to scale problems, it is almost impossible to visualize simultaneously actual distances and sizes in the Solar System. Then, it is the square root of the distances to the Sun that are displayed; when the Solar System is displayed without such a non linear scaling, the inner planets are "hidden" by the Sun. Moreover, the diameter of each celestial body is multiplied by a huge arbitrary factor.
