No, meteorites are not exclusive to Earth. They have been found on other celestial bodies, such as the Moon and Mars.
Research from NASA and various planetary science publications indicates that meteorites have been identified on the lunar surface, collected during the Apollo missions, and analyzed for their composition.
Similarly, meteorites have been discovered on Mars by rovers like Curiosity and Perseverance, which have identified iron-nickel meteorites on the Martian surface.
These findings are supported by studies published in journals like 'Earth and Planetary Science Letters' and reports from organizations such as the Lunar and Planetary Institute. The presence of meteorites on these bodies provides valuable insights into the solar system's history and the processes that shape planetary surfaces.
