Ganymede is the 13th Celestial Body and the 4th Moon obtained in The Beyond Bubble Universe, which can generate Stardust.

In-Game Description[]

"Ganymede is not only the largest Galilean moon, but also the largest moon in the entire solar system bigger even than the planet Mercury. It ha a thin oxygen atmosphere and its own magnetic field."



  • Magnetic Field (Speed):

"Ganymede is the only moon known to have a magnetic field. Although the field is small and relatively weak, it still makes Ganymede unique among the moons in our solar system."

  • Polar Caps (Payout):

"Like Earth, Ganymede has polar ice caps. Intense particle bombardment through the atmosphere creates a terrain of water frost at the moon's north and south poles."


  • Natural Satellites (Payout):

"Moons are defined by their orbit around larger celestial bodies. Most moons revolve around a planet, but smaller bodies can have moons, too - even particularly large asteroids."


  • Speed of Light (Speed):

"The speed of light is the rate at which light and all massless particles travel through a vacuum. While it can seen instantaneous from up close, over long distances this speed limit becomes very noticeable. The theory of relativity relates to the speed of light."

  • Cosmic Gravity (Payout):

"Gravity is one of the fundamental forces and key to understanding how the universe works. Using Newton's principles, astronomers can explain how stars and planets form, predict their mass and motion, and infer the existence of dark matter."

  • Goldilocks Zone (Discount):

"The Goldilocks Zone, also called the Habitable Zone, is the region around a star with conditions necessary for a planet that can sustain life. Planets like Earth, with surface water and breathable atmospheres, might be found in these zones in other systems."

Planetary Host[]

Ganymede's planetary host is Jupiter.


  • Simon Says (Rank 5):

"Simon Marius, a German astronomer, claimed to have observed Jupiter's moons a month before Galileo. This may have been true, but Galileo documented and published his findings first, and so is credited with the discovery."

  • Marquee Moon (Rank 8):

"Ganymede is the largest moon in our solar system. Its mass and diameter alone would classify it as a planet if it orbited the Sun instead of Jupiter. It is likely that it formed from gas and dust left over from Jupiter's creation."
