Yes, there are particles of Mars and Jupiter on Earth, but they are not in the form of intact pieces of the planets themselves. The particles I'm referring to are meteorites.
Meteorites are fragments of asteroids, comets, or other celestial bodies that survive their journey through Earth's atmosphere and land on the surface. Some meteorites come from Mars or Jupiter, and they provide scientists with valuable information about these planets.
Martian meteorites, also known as "Martian rocks" or "Mars meteorites," are pieces of Mars that were ejected into space due to impacts on the Martian surface. Over time, some of these meteorites made their way to Earth through various mechanisms and fell as meteorites.
Jupiter, being a gas giant, doesn't have a solid surface like Mars, so there are no meteorites that originate directly from Jupiter. However, there are meteorites known as "jovian meteorites" that are believed to have come from moons of Jupiter, such as Callisto, Ganymede, or Europa. These moons have undergone impacts from asteroids or comets, and the debris from those impacts can be ejected into space. Some of this material eventually finds its way to Earth as meteorites.
Scientists study these meteorites to learn about the composition, geology, and history of Mars, Jupiter's moons, and other celestial bodies in our solar system. They provide valuable insights into the processes that have shaped these objects and help us understand their evolution.
