class poliastro.frames.ecliptic.GeocentricSolarEcliptic(*args, copy=True, representation_type=None, differential_type=None, **kwargs)

This system has its X axis towards the Sun and its Z axis perpendicular to the plane of the Earth’s orbit around the Sun (positive North). This system is fixed with respect to the Earth-Sun line. It is convenient for specifying magnetospheric boundaries. It has also been widely adopted as the system for representing vector quantities in space physics databases.
