Why am I seeing falling stars

The phenomenon you’re describing, often referred to as “falling stars,” is actually the visible appearance of meteors entering Earth’s atmosphere and burning up due to friction with the air. These events are more formally known as meteoroids, and when they enter the Earth’s atmosphere and create a bright streak of light, they’re called meteors. Here’s how it works:

Meteoroids: Meteoroids are small rocky or metallic objects that orbit the Sun. They can vary in size from tiny particles to larger objects several meters in diameter. When a meteoroid enters the Earth’s atmosphere, it’s traveling at very high speeds, typically around 25 to 40 kilometers per second (55,000 to 90,000 miles per hour).

Friction and Heat: As a meteoroid enters the Earth’s atmosphere, it encounters the air molecules at high speeds. The friction generated by the rapid motion causes the meteoroid to heat up rapidly. This intense heating causes the outer layer of the meteoroid to vaporize, creating a glowing trail of hot gas and ions behind it.

Visible Streak: The glowing trail left behind by the meteoroid is what we see as a “falling star” or a meteor. This streak of light can vary in color and intensity depending on the composition of the meteoroid and the altitude at which it enters the atmosphere.

Burn Up: Most meteoroids are quite small, and due to the intense heat and friction, they burn up completely before reaching the Earth’s surface. Only the largest meteoroids, which are usually referred to as meteorites once they’ve landed, have the potential to survive the journey through the atmosphere and land on the ground.

Meteor Showers: Sometimes, Earth passes through areas of space where there’s a higher concentration of meteoroids. When this happens, we experience a meteor shower, which is a period when we see an increased number of meteors in the sky. Meteor showers occur predictably at specific times of the year when Earth’s orbit intersects the debris left behind by comets or asteroids.

Meteor showers can be quite spectacular, with dozens or even hundreds of meteors visible in an hour, especially in areas with minimal light pollution. If you’re seeing these “falling stars,” you might be witnessing individual meteors outside of a meteor shower, or you could be observing a sporadic meteor, which is a random meteor that is not associated with a known meteor shower.

So, the next time you spot a falling star, you’ll know that you’re witnessing a meteoroid blazing through Earth’s atmosphere and creating a brief and beautiful display of light.
