rogue planets

In science fiction, rogue planets are often depicted as desolate and mysterious worlds. They might be shown as cold, dark places with extreme conditions. For example, in some stories, they are home to strange and dangerous creatures that have evolved in isolation.

One of the well - known works is 'The Dark Beyond the Stars' which features a journey to a rogue planet. The planet in this story holds many secrets and the crew exploring it faces various perils.

In science fiction, rogue planets can have all kinds of wild features. They might be inhabited by strange alien species or have super - advanced technology left behind by a long - gone civilization. But in real - life theories, we mainly think about their formation and movement. Scientists are still trying to figure out how many there might be and how they interact with other celestial bodies.

The difference between stars and planets was their nature and composition. A star was a spherical luminous plasma condensed by gravity, like the sun. Stars generate energy through nuclear fusion reactions and radiate the energy into outer space. Planets, on the other hand, were celestial bodies that orbited stars and usually did not emit light. Planets were composed of solid, liquid, and gas, unlike stars, which had high temperatures. Stars were usually more massive than planets because stars could continue to undergo nuclear fusion reactions while planets could not. In addition, stars and planets moved differently. Stars moved on their own while planets moved around them. In short, there were obvious differences between stars and planets in terms of nature, composition, mass, and motion.

Science fiction planets differ from real ones in multiple ways. Firstly, the laws of physics might be bent on these fictional planets. For instance, some might have gravity that behaves in an unusual manner to create more interesting storylines. Secondly, the ecosystems can be completely fabricated. Instead of the real - world ecological balance, science - fiction planets can host creatures and plants that are a product of the author's wildest dreams, and they can be used as a backdrop to explore various themes like survival, exploration, and the encounter of different civilizations.

Under normal circumstances, it was impossible for a planet to become a star. Planets lacked the conditions to form stars, such as mass and energy. However, recently, scientists discovered a huge hot Jupiter called KELT-12b, which continuously absorbed the energy of its star, and its volume and temperature were constantly increasing. If Kelt-12b hadn't been swallowed by its mother star, it might have become a new sun. However, this situation was very rare and required special conditions and processes. Therefore, under normal circumstances, planets would not become stars.

Black holes were most afraid of white dwarfs. The scientists used the Kepler telescope to investigate the white dwarf and found that there were many rock stars around the white dwarf. These rock stars were very small. Whenever the white dwarf rotated, it would instantly chew up the asteroid, indicating that the white dwarf had the ability to disintegrate and destroy other cosmic objects. The black hole was afraid of the collision of all the planets of the neutron star. There was a competitive relationship between the black hole and all the planets, white holes, and wormholes. However, there was no mention of whether black holes were afraid of magma or whether there were planets inside black holes.

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.

Hoth from 'Star Wars' is a well - known ice planet. It has a harsh, frozen environment and is home to various dangerous creatures.
