Ablation removes material from 2026 Perseid particles as they enter Earth’s atmosphere.
Ablation is the loss of material from a meteoroid during its high-speed atmospheric passage. The particle encounters dense air, becomes intensely heated, and sheds or vaporizes material. The surrounding gas is also excited and ionized, producing the luminous meteor trail seen from the ground.
This process is why most Perseid particles disappear before reaching Earth’s surface. Their small size and extreme entry speed allow atmospheric interaction to consume them rapidly, although larger fragments can behave differently.
Ablation is related to the meteor’s glow but is not identical to every process involved. Heating, compression, excitation, ionization, fragmentation, and vaporization all contribute to the observed streak. The concise scientific term for the particle’s material loss is ablation.
