Possible appearance of a large gas giant in the Helvetios system, designated Dimidium or 51 Pegasi b, shown here with two hypothetical moons.

A yellow dwarf similar in size and structure to the Earth's own Sun, and some fifty light years from the Solar System. Helvetios (also known by its Flamsteed designation of 51 Pegasi) is important as possessing a planetary system.
