The trajectories of Mars (red) and of the Sun (yellow) are displayed as viewed
from a Earth-like planet (blue). 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- (see figure "The journey of an Earth-like planet (blue) from Mars (red) to the Sun (yellow) -extrapolation-").
For each intermediate Earth trajectory, the 3-body system is visualized
with the Earth at the origin of coordinates. Each of the displayed trajectories
has a duration equals to one martian year.
