The Block System

The Block System is a system in which Numberblocks take place.

Numberland/Planet 1
Numberland is the first planet in the Block System. Despite being the closest to it's star, Epekatasmius, it is completely habitable.
 * Scientific name: Pano-Arithmo/Enacius
 * Terrain: Forests, deserts, plains, oceans, etc.

Planet 2
While it's terrain is unknown, it is known that if it were to be in the Solar System it would be in the orbit of Venus.
 * Scientific name: Duolius

Planet 3
The third planet in the Block System, It isn't known of it's terrain.
 * Scientific name: Treisius

Planet 4
Planet 4 is a calming, vast planet. According to a study by Jay, it has strange, triangular structures and that the prototype numberblocks live there.
 * Scientific name: Tesseracius

Planet 5
Planet 5 is a chilling planet with a icy atmosphere that gives it a beautiful look from outer space. Inside the planet has a raging, unexpected storm as big as 25 football fields.
 * Scientific name: Pentantum/Enasterilous

Planet 6
Known to 6 and Xuya as Hexacius, Planet 6 has a scary signal when heard. It's atmosphere is warm, but gets hotter when going deeper and deeper in this planet.
 * Scientific name: Hexacius

Planet 7
Planet 7 has active volcanoes that should be stayed away from Numberblocks. It also has global arouras each leap year.
 * Scientific name: Heptasm

Planet 8
Despite it's distance from Epekatasmius, the surface of the planet can reach 72 degrees Celsius. Numberblocks are more likely to burn up, but they would usually survive with a special suit that ignores the laws of physics known as "The Astro-Suit 2000" (not on scratch).
 * Scientific name: Octal Demise

Planet 9 (and no, not the real planet 9)
Despite the atmosphere that gives the look outer space, landing on it provides a habitable environment. Landslides are most likely to happen, and never occur in leap years like 2040, 1980, etc.
 * Scientific name: Ix-Solitude

Planet 10
As it's orbit is really far, it has molten lava on the surface anyways. Numberblocks are more likely scared to visit.
 * Scientific name: Dekaland
