The Quadrantids meteor shower, which will peak between January 3 and 4, is the first major meteor shower of the year. This meteor shower stands out because it is believed to originate from an asteroid, making it an unusual occurrence in the sky.
The discovery of the Quadrantids meteor shower can be credited to the Italian astronomer Antonio Brucalassi in 1825. Scientists suspect that this meteor shower comes from the comet C/1490 Y1, which was first observed by Japanese, Chinese, and Korean astronomers over 500 years ago.
NASA identifies the Quadrantids as one of the best annual meteor showers, known for its “bright fireball meteors.” These meteors are particularly stunning and captivating to witness.
The Quadrantids appear to radiate from the extinct constellation Quadrans Muralis, now considered part of the Boötes constellation and located not far from the Big Dipper. However, due to the constellation’s position in the sky, the shower is often not visible in the Southern Hemisphere. There is a slim chance of spotting it up to 51 degrees south latitude.
The most favorable regions for observing this meteor shower are countries with high northern latitudes such as Norway, Sweden, Canada, and Finland.
If you happen to miss the Quadrantids meteor shower, don’t fret. There are plenty of other opportunities throughout the year to witness the enchanting display of streaks of light across the night sky.

Understanding Meteor Showers
A meteor shower occurs when Earth passes through the debris stream in the orbit of a comet. In simpler terms, it is when multiple meteors flash across the sky from roughly the same point.
Although meteors are often referred to as shooting stars, they are not related to actual stars. These showers seem to originate from a single point in the sky called the shower radiant, and our perspective gives them the appearance of emanating from that point. When a particle, about the size of a grain of sand, enters Earth’s atmosphere at a speed of 134,000mph, it vaporizes and creates a typical meteor.
If a particle is larger than a grape, it produces a fireball and leaves behind a glowing trail known as a meteor train. This trail is formed by ionized gas slowly dissipating its energy.
Meteors, Meteoroids, and Meteorites
A meteor is a meteoroid, which is a particle broken off from an asteroid or comet orbiting the Sun. When a meteoroid enters Earth’s atmosphere, it burns up, creating the phenomenon known as a shooting star.
If a meteoroid reaches Earth’s surface without disintegrating, it is called a meteorite.
Meteors are typically composed of comet dust and ice, no larger than a grain of rice. On the other hand, meteorites consist of rocks that have broken off from asteroids found in the asteroid belt between Mars and Jupiter, sometimes weighing up to 60 tonnes. There are different types of meteorites, including “stony” ones rich in silicon and oxygen, “iron” meteorites mainly composed of iron and nickel, and “stony-iron” meteorites that combine both elements.
NASA estimates that between 1,000 to more than 10,000 tons of meteor material falls on Earth every day, but the majority is in the form of dust-like grains and poses no threat to our planet. Remarkably, there have only been two recorded incidents of injuries caused by meteorites, with one incident involving a woman who was bruised when an eight-pound meteorite fell through her roof in 1954.
Upcoming Meteor Showers in 2023
Lyrid Meteor Shower
Meteors in the Lyrid shower travel at approximately 107,000mph and explode around 55 miles above Earth’s atmosphere. These meteors, often referred to as “Lyrid fireballs,” momentarily cast shadows before leaving smoky debris trails that can linger for several minutes.
The Lyrid shower is visible in both the Northern and Southern Hemispheres, providing stargazers with an opportunity to witness up to 18 meteors per hour during its peak. The glowing streaks in the night sky are the result of ionized gas burning up as it enters Earth’s atmosphere. These streaks are created by small comet dust flakes, typically no larger than grains of sand, that travel at speeds of 110,000mph and disintegrate.
