Approximately how fast do 2026 Perseid meteoroids enter Earth’s atmosphere?

2026 Perseid meteoroids enter Earth’s atmosphere at approximately 58.8 kilometres per second.

That speed is the characteristic entry velocity associated with the Perseid stream. It helps explain why Perseid meteors often appear bright and leave swift, sharply defined streaks across the sky.

A meteoroid is the solid particle in space. Once it enters the atmosphere and produces a visible luminous trail, it is called a meteor. If any fragment survives to reach the ground, it is called a meteorite. The visible streak is therefore not a solid object flying through empty space; it is light produced as the particle interacts with atmospheric gases.

The speed is not the same as the speed of Earth around the Sun. Earth’s orbital motion contributes to the encounter geometry, and the quoted figure is the shower’s atmospheric entry velocity. Individual appearances can differ because particles have different sizes, paths and brightnesses.
