Mercury is the smallest planet in the Sol system.
When the player first enters Mercury, they will find a plain Arid Planet with only one large crater (perhaps Caloris Basin). It has Purple or Yellow Spice, which can be harvested by the player.
These landforms can be found on Mercury in real life.
- Mercury's spice color differs between some games as in some it has Purple Spice, while in others it has just plain Yellow spice.
- Spore's Mercury is orange, but the real life Mercury is brown.
