Earth

"A desolate, ruined world. Home of the oppressive Grineer Empire."

- In-game description

 is the first planet accessible to player and where the Grineer are the controlling faction.

The boss that used to reside on this planet was Councilor Vay Hek who used to drop components for the Oberon Warframe, and before that, the Trinity Warframe. After being revamped, Vay Hek is still fought on Earth but does not reside in a mission node. The only way to have access to Vay Hek now is to use Beacons to make a key. He now drops components for the Hydroid Warframe, as well as rewards the Saviour of Earth achievement. (See Councilor Vay Hek for more details.)

The Strata Relay was located here, but it was the first player hub destroyed by Vay Hek's Balor Fomorian in the Eyes of Blight event.

Expected Enemies
''Infested can appear during Invasion missions. These lists do not apply to Survival missions.''
