Planet 03 · Terrestrial ocean world
The only known world with a living ocean.
Earth is the largest rocky planet and the only place known to host life. Liquid surface water, plate tectonics, a protective magnetic field, and a nitrogen-oxygen atmosphere make it unlike every other world we have examined.
World profile
About 78% nitrogen, 21% oxygen, and 1% other gases.
A moving rocky crust with continents, ocean basins, ice, and active plate tectonics.
Global average about 59 °F (15 °C)
One — the Moon
Composition
Field notes
Earth is the only planet known to keep stable liquid water on its surface.
The moving liquid-metal outer core generates the magnetic field that helps shield the atmosphere.
The leading model for the Moon's origin starts with a giant impact into the young Earth.
Sourced image archive
Every image keeps its credit, capture date, description, and original source. Mission imagery links back into the same Andromeda mission catalog.

A Mitsubishi Heavy Industries H-IIA rocket launched the IGS-Optical 8 mission on Friday, January 12, 2024 at 4:44 AM (UTC).
View in 3D map — IGS-Optical 8Associations use destination records plus a curated cross-world manifest for flybys and gravity assists. Mission-name collisions such as Project Mercury and Saturn launch vehicles are deliberately kept with Earth unless they actually visited the planet. Technically obvious; historically necessary.
