Upsilon Andromedae Gallery

Note: The respective sizes in the artist renderings are schematic only; we do not really know the sizes of these giant planets (here they are depicted with their respective volume proportional to the inferred minimum mass).
The relative rotation speeds and distances are acurate (but the orbits eccentricities are not taken into account yet). The short movie corresponds to 10 rotations of "b" and thus corresponds to 46 days, the long movie starts `earlier', and corresponds to a 4-month-long span.
