One planet type is the volcanic planet. It has a high level of volcanic activity, with lava flows and a very hot and unstable environment. Mercury in our solar system has some similarities but in science fiction, they can be much more extreme. Another is the artificial planet, created by an advanced civilization. These can have all sorts of incredible structures and technologies. They might be self - sustaining habitats or even weapons platforms in some stories.
Platinum is another metal that appears in science fiction. It could be used in advanced medical devices in a futuristic setting. Also, fictional metals like unobtainium are common. Unobtainium is often used to represent a metal that has ideal but currently unachievable properties, like being a perfect conductor or having the ability to defy gravity, which drives the plot in many science fiction stories as characters strive to obtain or understand it.
There are many common character types in science fiction. One is the heroic scientist, like Dr. Ellie Arroway in 'Contact'. They are intelligent, curious, and often on a quest for knowledge or to save the world. Another type is the space adventurer, for example, Han Solo from 'Star Wars'. They are brave, often a bit of a rogue, and skilled in combat and flying spaceships. There are also the alien characters which can range from menacing invaders like the Xenomorphs in 'Alien' to the more benevolent ones like E.T.
The common types include telepathy, which is the ability to read or communicate with minds. Telekinesis is also popular, where one can move objects with the mind. And there's precognition, being able to see future events.
In science fiction, conflict often arises between different ideologies. For instance, in 'Star Trek', the Federation's ideology of peace, exploration and cooperation sometimes clashes with other species' more aggressive or self - interested views. Also, there can be environmental conflicts. In some post - apocalyptic sci - fi stories, survivors have to deal with the conflict of a ruined environment that's hostile to life, like in 'Mad Max' movies.
Some common ship types in science fiction are starships. They are often used for interstellar travel. Another type is the spaceship, which can range from small exploration vessels to large battle cruisers. And there are also generation ships, designed to carry a population for long - term space travel, like in some dystopian science fiction scenarios.
Well, the most common types of science fiction are space opera, where adventures take place in vast cosmic settings, and time travel stories that explore the possibilities of going back and forth in time. Another type is post-apocalyptic, imagining worlds after a major catastrophe.
One common feature could be an exotic landscape. Maybe it has floating mountains or luminous lakes.
One common theme is the exploration of unique ecosystems on micro planets. These could be places with strange flora and fauna that have adapted to the planet's small size and specific conditions.
One common theme is exploration. In distant planet science fiction, characters often embark on voyages to discover new worlds, like in 'Star Trek' where they explore various planets. Another theme is the encounter with alien life forms. It can range from friendly cooperation to hostile battles. Also, the concept of adapting to alien environments is prevalent, for example, how humans might have to modify their biology or technology to survive on a distant planet with extreme conditions.
One common theme is exploration. Writers often depict the exploration of the home planet in ways we haven't yet in real life, like exploring hidden underground civilizations or long - forgotten ancient structures.

This might involve characters struggling to survive in a post - apocalyptic version of the home planet.
