Mercury is the 2nd Celestial Body and the 1st Terrestrial Planet obtained in The Beyond Bubble Universe, which can generate stardust.

In-Game Description[]

"Mercury is the smallest planet in the solar system, as well as the closest to the Sun. With its rocky grey surface, thin atmosphere, and small size, Mercury could easily be misteken for a moon."



  • Large Iron Core (Speed):

"Scientists believe that Mercury has a massive iron core that makes up more than 75% of the planet's radius. Covered by a thin, rocky crust, this core contributes to the planet's high density."

  • Temperature Fluctuations (Payout):

"Even though Mercury is the closest planet to the Sun, it can be both incredibly hot and extremely cold. With temperatures swinging from 450 degrees to -170 degrees Celcius, its climate is truly inhospitable."


  • Solid Surface (Payout):

"All terrestial planets have a solid surface with a silicate mantle over a metallic core. Varying levels of seismic activity create mountains, canyons, craters, and volcanoes."


  • 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."


  • God of Messengers (Rank 5):

"Because it's closest to the Sun, Mercury appears to move through the sky more quickly than the other planets. It gets its name from the swift Roman god of messengers, who flew using winged sandals."

  • Honey, I Shrunk the Planet (Rank 10):

"Mercury is actually in a continuous state of shrinkage. Because its surface is composed of only one tectonic plate over a molten core, the planet contracts as the core cools over time. This process has created deep canyons on the planet."
