The Martian atmosphere is thinner and the magnetic field isn't present. I wonder how many asteroids fall and if at least the small ones can burn in the atmosphere before reaching the soil. Thanks in advance for your answers.
It depends on what its made of, how fast it is traveling, etc.. The atmosphere of Mars being at the most around 2% of Earth's and most meteors 25 meters or less will break up in Earth atmosphere. Then a meteor less than .5 meters should break up on Mars. You can call a meteor that will make impact an asteroid.
