Common features of hostile planets in science fiction include inhospitable climates. This could be a planet that has a never - ending rain of acid which would corrode anything not made of special materials. There are also planets where the electromagnetic fields are so chaotic that they disrupt all communication and navigation systems. Moreover, some hostile planets might be covered in a thick, gooey slime that is not only difficult to traverse but also contains organisms that can attach to and parasitize any living thing that comes into contact with it.
In science fiction, hostile planets are often depicted as places with extreme conditions. For example, the planet Pandora in 'Avatar' has a toxic atmosphere and dangerous wildlife. These planets serve as great backdrops for adventure stories, forcing characters to adapt or die.
One of the most memorable is Tatooine from 'Star Wars'. It has a harsh desert environment and is home to dangerous creatures like the Sarlacc. The dual suns also add to its uniqueness.
A common feature is a unique ecosystem. They often have species that are exclusive to that planet and have co - evolved with the planet itself. Another feature can be a kind of energy source that is unique to the living planet, like a special type of radiation or a force field.
They often rely on advanced technology. For instance, special suits that can protect them from the harsh environment, like suits with built - in air - purification systems for planets with toxic atmospheres. They also use ships or shelters that are well - equipped to withstand the planet's threats, such as reinforced hulls against strong gravitational forces.
Arrakis from 'Dune' is very famous. It's known as the desert planet and is crucial for the spice melange. Another is Coruscant from 'Star Wars', a planet - wide city.
Arrakis from 'Dune'. It's a desert planet, very famous in science fiction. The harsh environment and the valuable 'spice' found there make it a central setting in the story.
Common elements in science fiction regarding green planets' ecology include a very rich biodiversity. There are often plants that have properties that seem magical, like healing powers or the ability to emit energy. The animals are also adapted to the lush environment in interesting ways. For example, they might be able to fly between the tall trees easily. And the whole ecosystem seems to be more in tune with the planet itself, as if the planet has a sort of consciousness that the ecology is a part of.
Cybertron from the 'Transformers' franchise. It's the home planet of the Transformers, a race of sentient robotic beings. The planet has a long and complex history filled with war and technological evolution.
In science fiction, Earth and Mars are often connected. Many stories depict humans traveling between the two planets for various reasons like colonization, resource extraction, or scientific research. For example, in 'The Martian', the connection between Earth and Mars is crucial for the survival of the stranded astronaut on Mars as Earth tries to send him supplies and figure out a way to bring him back.
In general, there is no strict rule that planets must be italicized in science fiction. It often depends on the style guide of the publisher or the author's personal preference.
