Interesting fact: Most meteors you see at night are caused by tiny particles, sometimes no bigger than grains of sand, burning up high in the atmosphere.
The answer: A meteor can weigh almost anything from tiny dust-sized grains to massive space rocks. For example, a stony meteoroid about 1 meter across often weighs roughly 3,000 to 4,000 kilograms before atmospheric entry.
Meteor weight is hard to pin down because the object loses mass as it heats, fragments, and burns through the atmosphere. Scientists estimate original mass from brightness, speed, recovered fragments, and composition. Knowing meteor mass matters for impact risk, planetary defense, crater formation studies, and understanding what material from space reaches Earth.
