What is Meteor? | Meteoroid

Meteor | Meteoroid

Meteor, meteorite, and meteoroid are all the same but we call it by different names, depends on where it is found.

All these are related to flashes of light called shooting stars.

A meteoroid is a small particle from a comet or asteroid orbiting the Sun.

Meteor is the light phenomenon that occurs when a Meteoroid enters Earth’s atmosphere and vaporizes.

A meteorite is a meteoroid that survives its passage through Earth’s atmosphere and lands upon Earth’s surface.

Basically, Meteor known as a shooting star or falling star is visible passage glowing of meteoroid or comet or asteroid from Earth’s atmosphere. Millions of meteors occur on Earth’s atmosphere daily. Most of the meteoroids are of a size of a grain of sand that means they are of millimeter-sized or smaller. Meteors may occur in showers, which happens when Earth passes through a stream of debris left by a comet. Meteors become visible between about 75 to 120 km (250,000 to 390,000 ft) above Earth. When Earth encounters many meteoroids at the same time, we call it a meteor shower. The atmospheric velocities of meteors result from the movement of Earth around the Sun at about 30 km/s (67,000 mph),  the orbital speeds of meteoroids, and the gravity well of Earth.

When the meteor shower takes place, the glowing streak may appear anywhere in the sky, but their tails all seem to point at the same spot in the sky. This is because all meteors are coming at the same angle and as they start getting closer to Earth the effect of perspective makes them seem to get farther apart.

Meteors have 50 % of the chances of being observed in daylight. They can usually observe at night when darkness allowed fainter objects to be visible. Most of the meteors glow for a second. Meteors have been known since ancient times, but they were not known to be an astronomical phenomenon until early in the nineteenth century.

The meteor shower is named for the constellation where the meteors appear to be coming from.
