# Is there an estimate for the average mass of all meteoroids and asteroids hitting Earth's atmosphere in one year?

I wonder how much mass is entering Earth's atmosphere every year in the form of meteoroids and asteroids. This excludes micro-meteoroids, dust particles, molecules etc.

Quick search result talks only about the number of object:

Every year, the Earth is hit by about 6100 meteors large enough to reach the ground, or about 17 every day, research has revealed.

Background: comparison of this natural reentry mass to the mass of reentering satellites, What impact will the deorbiting of thousands of satellites have on the atmosphere?

• Did you try to look up "meteorites flux"? You will have to specify a minimum mass for exclusion of objects you do not consider as dangerous to get a meaningful answer. Also, mass alone will not suffice for comparison. Satellites are made in materials that disintegrate easily in the atmosphere. Regardless, you will not have difficulty convincing, w/o requiring "scientific" arguments, that a plane is more likely to be hit by a meteorite than by a decaying satellite or man-made orbiting objects. The only differences is in liability. Jun 23, 2021 at 10:58
• NASA states 44 tonnes of meteoritic material falls on the Earth each day.

• In Earth Science SE: Is Earth getting heavier or lighter? and various linked sources, and in Astronomy SE: If 50 tons or more of debris falls to earth everyday, is Earth getting heavier?

• We use 3 distinct terms here: meteorid, meteorite and meteor. The differences are given by Britannica here. The OP's source: 17 meteorites reach the ground per day. Fred's NASA source (my interpretation): the Earth (and its atmosphere) crosses a cloud of 44 metric tons of meteors/day. In other terms, the Earth captures 44t of meteorids/day. Otherwise, the numbers would not be coherent (17 meteorites landed for a total of 44T today !?). Jun 23, 2021 at 14:30
• @Fred thanks that's what I've been looking for Jun 25, 2021 at 10:42
