Exoplanets are planets that exist outside of our solar system and orbit other stars. They come in a wide variety of sizes, compositions, and environments, ranging from small rocky planets like Earth to massive gas giants like Jupiter. Some exoplanets are in the habitable zone of their star, where the conditions may be suitable for liquid water and, potentially life.
The solar system is the planetary system that includes the Sun and all the objects that orbit around it. The eight planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The inner planets are small and rocky, while the outer planets are gas giants made mostly of hydrogen and helium.
Biohacking refers to the practice of using technology, biology, and self-experimentation to enhance physical and cognitive performance, improve health, and extend human capabilities beyond their natural limits.
