Star Trek and Star Wars are both popular science fiction franchises, but they differ in several ways. Here are some key differences:

Tone: Star Trek tends to be more cerebral and philosophical, exploring themes such as ethics, diplomacy, and the nature of humanity, while Star Wars is more action-packed and focused on epic battles between good and evil.

Setting: Star Trek takes place primarily in the future, with a focus on space exploration and a utopian vision of humanity's future. Star Wars, on the other hand, takes place "a long time ago in a galaxy far, far away," and has a more mythic, fantasy-like feel.

Technology: Star Trek is known for its emphasis on technology, with advanced spaceships, gadgets, and scientific concepts often playing a central role in the stories. Star Wars, on the other hand, is more focused on the Force, a mystical energy field that can be harnessed by certain individuals.

Characters: Star Trek tends to focus on ensemble casts, with a diverse group of characters working together to solve problems and overcome challenges. Star Wars has iconic characters such as Luke Skywalker, Darth Vader, and Han Solo, and is more focused on their individual journeys.

Visual style: Star Trek has a more sleek and futuristic visual style, with clean lines and a minimalist aesthetic, while Star Wars is known for its ornate, lived-in look, with detailed sets and costumes that show wear and tear.

Storytelling: Star Trek is known for its episodic format, with individual episodes often telling self-contained stories that explore a particular theme or idea. While there are overarching plotlines and character development over the course of a season, each episode can generally be enjoyed on its own. Star Wars, on the other hand, has a more serialized format, with each movie building on the events of the previous ones and contributing to an ongoing narrative.

Philosophy: Star Trek often explores philosophical ideas and ethical dilemmas, with characters debating the best course of action in complex situations. Star Wars, while it touches on similar themes, is more focused on the struggle between good and evil and the power of the Force.

Humor: Star Trek often includes humor, with characters cracking jokes and engaging in witty banter. Star Wars has moments of levity, but is generally more serious in tone.

Fan culture: Both franchises have passionate fan bases, but they have different cultures. Star Trek fans are known for their love of the franchise's intellectual and scientific themes, as well as their fondness for cosplay and conventions. Star Wars fans are known for their love of the films' iconic characters and memorable moments, as well as their interest in the expanded universe of novels, comics, and video games.

Influence: Star Trek and Star Wars have both had a significant impact on popular culture, inspiring countless imitators and influencing generations of creators. However, their impact has been felt in different ways, with Star Trek often cited as an inspiration for real-world technological advances and Star Wars influencing the look and feel of countless sci-fi and fantasy films and TV shows.

Overall, while both franchises have a devoted fanbase and have made significant contributions to science fiction and popular culture, they have distinct differences in tone, setting, technology, characters, and visual style.
