This page shows the current positions and other interesting data of the five
spacecraft which are leaving the Solar System on escape trajectories - our first
emissaries to the stars. The graphics and data table are generated dynamically
and so always represent the latest positions. The recently launched New Horizons
spacecraft has been added to the table, but will only be shown in the charts when its
distance from the Sun has increased.
