'''Planets''' are celestial objects in the [[Milky Way]] galaxy. They are found in systems orbiting stars. Planets themselves are sometimes orbited by both [[natural satellite]]s and artificial [[space station]]s. [[City|Cities]] are also often built on planetary surfaces.

{{Main|Terraforming}}

Terraforming is a series of processes to make planets suitable for habitation.{{Ref/Novel|Novel=Halo: Ghosts of Onyx}} It can take several centuries to fully terraform an Earth-sized planet, depending on what is needed.<ref>''[[Halo: Reach]]'', [[Data pads|Data pad 14]]</ref> Humans first began terraforming around the 22nd-century in the Sol system.<ref>''[[Halo Encyclopedia (2009 edition)]]'', p. 42 (2011)</ref> The [[Covenant]] can terraform worlds solely to produce [[plasma]].<ref>''[[Halo: Escalation]]'', Issues 1-2</ref> The [[Flood]] could also terraform, by altering the atmosphere of worlds they touched.{{Ref/Level|Game=Halo: Combat Evolved|Level=The Library|Quote=Your environment suit will serve you well when the Flood begin to alter the atmosphere - you are a good planner!}}

===Slipspace affects===

{{Main|Slipstream space}}

Planets can generate enough of a gravitational force that it can affect the superfine quantum filaments that are needed for slipspace drives; something UNSC calculations couldn't figure out. Covenant drives, which originate from Forerunner drives aren't affected by this.<ref>''[[Halo: First Strike]]'', p. 85</ref>
