Dust Facts

Every day, approximately 100 tons of extraterrestrial material, mostly in the form of tiny space dust particles, enters Earth's atmosphere, contributing to our planet's ever-so-slight increase in mass.

Dead skin cells make up about 20-50% of the dust in your home, not most of it as commonly believed.

When considering magnitudes logarithmically, a typical speck of dust visible floating in the air is approximately the geometric mean in size between the Earth and a subatomic particle like a proton.

The Earth gets heavier each day by tons, as meteoric dust settles on it.

In the average lifetime, a person will breathe in about 40 to 50 pounds of dust.

A single speck of dust is half way in size between a subatomic particle and the Earth.
