Earth

Earth (also referred to as Ancient Er by the Ostrons) is the homeworld of humanity but has been mostly abandoned millennia ago, its surface largely overtaken by a large, mutated jungle structure. The have taken control over this planet, intending to poison the forest and build their empire over it. It is the first planet players can access, and is linked to Mars and Venus Junctions. And once the player has completed The Second Dream quest, Earth will then be connected to Lua as well.
Earth is the only planet to feature the Grineer Forest Tileset. Every four hours, the forest tileset will change from day to night, mimicking the day cycles in real life. The change will feature different vegetation that can be scanned for extracts that are used to craft Antitoxins, Apothics and medical regeneration packs, with Sunlight variants during the day and Moonlight variants at night.
The Assassination Target for Earth is Councilor Vay Hek, located in the mission node Oro. Unlike the nodes of bosses on other planets, his node is not able to be accessed until the player is of Mastery Rank 5, which is typically achieved much later in the Star Chart. Vay Hek drops the component blueprints and parts of the Warframe, and his defeat is a requirement in the Sedna Junction on Pluto.
Earth also features a Landscape: the Plains of Eidolon. Rather than featuring a jungle like most of Earth, the Plains consists of a wide, open terrain containing the remains of an ancient battlefield and the ruins of an enormous Sentient. Nearby is the Ostron Town of Cetus, a player hub which is home to the Ostrons, a colony of peaceful merchants and also an access point to the Plains.
The secret Steel Meridian enclave known as Iron Wake is also located on Earth, becoming available through the completion of the Chains of Harrow quest. Palladino can be found there.
The space around Earth is a playable area in the Empyrean gamemode, featuring its own Grineer enemies. It is called Earth Proxima.

==Missions==
==Tips==
*Earth is the easiest place to farm Neurodes, with a large amount of low leveled enemies making it excellent for longer farming runs.
*Earth is the only place where Feral Kubrows, and by extension Kubrow Eggs, can be found since only Earth has Kubrow Dens.
*There are resources that can only be obtained on the Plains of Eidolon, through deposits, fishing or mining.
==Trivia==
*Before Vor's Prize, Earth had higher level enemies similar to that of Mars, as Mercury was the starting planet instead.
*Earth never has Invasions or Infestation Outbreaks. No explanation for this has been given by Digital Extremes.
*Most of the names of Earth's missions are from a variety of Earth-related topics, such as:
**Key features of Earth itself (Pacific, Everest, Mariana, Eurasia).
**Various geological events and formations pertaining to Earth (Lith, Cambria, Mantle, Oro).
**The personification of the Earth in Greek Mythology (Gaia).
*Despite being previously described as a "desolate, ruined world" Earth has very lush forests, which Vay Hek tried to destroy during The Cicero Crisis. This original description is probably no longer canon.
**The lore behind the founding of Cetus, which describes the founders of Cetus having found a place free of poisons on an otherwise toxic planet, suggests that it is probably still canon, but that most of Earth, even if forest, remains toxic to normal humans.
***From the navigation map, Earth appears to be mostly rendered into desert, with southern Africa appearing either flooded or forested and most of central Europe covered in a dark shadow which could be scorched earth or dense, dark vegetation. It is possible that the forests, however small, are simply the only places with small enough concentrations of Grineer and valuable enough resources to be worth occupying.
***The Scarlet Spear Flotilla Relay possesses a hologram of Earth that shows the planet to still be the same as it appears today.
*The Strata Relay was the first player hub destroyed on the PC version of Warframe by one of Vay Hek's Balor Fomorians during the Eyes of Blight event.
**It was also the first Relay to be rebuilt on the PC version of Warframe during The Pyrus Project, nearly three and a half years later.
*Earth is the earliest planet on which Wildlife can be encountered, as it is home to Feral Kubrows, Condrocs, Kuakas, Mergoos and Vasca Kavats, as well as a variety of fish species.
**Kubrow Dens can only be encountered on the Grineer Forest tileset, which is only used on Earth. This means that Kubrow Eggs can only be obtained on Earth.
**The existence of the Feral Kubrow on the Grineer Forest tileset means also that Earth is the earliest planet on which Kubrow Mods can be obtained.
*Earth seems to have the largest variety of enemy levels in the game, with most missions being at levels 1-8, Vay Hek's Assassination at 20-25, and tier 5 Plains of Eidolon bounties at 40-60.
*Earth also has the largest varieties of Grineer enemies, with regular, Frontier, Drekar and Tusk Grineer being available on the planet.
*Earth is the first and only planet to have a day-night cycle, which changes every 4 hours (at 12, 4, 8am, and 12, 4, 8pm Eastern Standard Time)
**The Plains of Eidolon follow a different day/night cycle from the rest of the Earth nodes.
*Earth and Europa are the only planets to feature no Survival missions (in Earth's case, due primarily to the large presence of the Grineer Forest tileset which features Excavation missions instead).
*Plains of Eidolon was released in Update 22, and was the first landscape to be added in the game.
**Since the Plains release Maroo's Bazaar has been relocated to Mars.
