Terra is a type of planet similar to Earthlike; they share similar biomes and appearance, but the colour, gravity, temperature, and other attributes vary from planet to planet.
Features
Terra planets feature a range of biomes, namely tundra, desert, plains, and ocean. There are resource nodes and mountains scattered across the land, and unlike Earthlikes planets, also contain random and additional materials, like Titanium.
Snow, grass, wood, and water are all present on terra planets, and can be obtained without using hydroponics and melters.
The tint of grass, sand, snow, stone, and water is entirely random and you are likely to come across bizarre landscapes.
It is arguably the best planet type for a colony, as it accommodates multiple climates while maintaining a lukewarm temperature, and you do not have to set up different machines to gather unavailable materials.
