They are almost always small enough to rapidly combust in our atmosphere, so there is little chance that any of them will strike the surface of the Earth.
What Is a Meteor Shower: If a meteor shower is occurring, you will not need a telescope, binoculars, or a high mountain to have a “star gazing” celebration. You may require a warm sleeping bag and an alarm clock to rouse you during the night. However, simply lying down in your own backyard will place you in the ideal position to watch a great show.

A meteor is a meteoroid or other space rock that penetrates the Earth’s atmosphere. As the space rock descends towards the Earth, the air’s resistance, or drag, causes it to become extremely hot. The object observed is a “shooting star.” This luminous streak is not the rock itself, but rather glowing hot air caused by the rock’s passage through the atmosphere.
When Earth is bombarded by numerous meteoroids at once, we refer to it as a meteor shower.
The diagram depicts the Sun in the centre, the Earth orbiting, and a comet orbit intersecting the Earth’s orbit.
Why would Earth encounter numerous meteoroids simultaneously? As with Earth and the other planets, comets orbit the sun. In contrast to the nearly circular orbits of planets, the orbits of comets are typically quite asymmetrical.
As a comet approaches the sun, a portion of its frigid surface evaporates, releasing large quantities of dust and rock particles. This comet debris is dispersed along the comet’s path, particularly in the inner solar system (where we reside) as the sun’s radiation melts more ice and debris. Several times each year, as the Earth travels around the sun, its orbit crosses the orbit of a comet, causing it to collide with comet debris.

Typically, meteoroids range in size from dust particles to boulders. They are almost always small enough to rapidly combust in our atmosphere, so there is little chance that any of them will strike the surface of the Earth. However, there is a good possibility of observing a spectacular shooting star display in the middle of the night!
In the case of a meteor shower, the glowing trails may appear anywhere in the sky, but their “tails” appear to all point in the same direction. This is due to the fact that all meteors are approaching at the same inclination, and as they approach Earth, the effect of perspective causes them to appear further apart. Comparable to standing in the midst of two railway tracks and observing their distant intersection.
Meteor showers are named after the constellation from which they appear to originate. Thus, the Orionids Meteor Shower, which occurs annually in October, appears to originate near the constellation Orion the Hunter.
Here are the dates of significant meteor storms. Each year, peak viewing periods will vary by one or two days. Consider that if the moon is full or near full, you may see fewer meteors. Some years have a greater number of meteors per hour than others.
