Study outlines seven stages of a space rock’s passage through Earth’s atmosphere
A Universe Today report describes a seven-stage sequence for a space rock traveling through Earth’s atmosphere before reaching the ground. The passage can take only a few seconds, while observations of the process may help scientists investigate a rock’s origin and assess potential damage if it explodes in mid-air.
A report by Universe Today describes the passage of a space rock through Earth’s atmosphere as a seven-stage journey that can end with an impact on the ground.
The report says the journey takes only a few seconds. It also distinguishes a meteor from other commonly used terms for bright objects or streaks seen across the sky.
According to the report, studying what happens during atmospheric entry may help scientists learn about a space rock’s origin and evaluate the potential damage it could cause if it explodes in mid-air.
