How much cosmic dust enters the atmosphere each year?

Approximately 40,000 to 100,000 tons of cosmic dust enter Earth's atmosphere each year. Most of this dust is tiny particles from comets and asteroid collisions, and as they enter the atmosphere, they burn up due to friction with the air, creating meteor showers. While this influx contributes to the overall mass of the Earth, it is minuscule compared to the planet's total mass.
