WASHINGTON — When the Quadrantid meteor shower reaches its peak on Friday, it will represent the year’s initial opportunity to witness fireballs illuminating the sky.
A diminishing crescent moon guarantees excellent visibility in clear, dark conditions.
Most meteor showers derive their names from the constellations they seem to radiate from in the nighttime sky. However, the Quadrantids “acquire their name from a constellation that no longer exists,” stated NASA’s William Cooke.
These meteors typically lack long tails, yet their heads can manifest as brilliant fireballs. According to NASA, the peak may display up to 120 meteors each hour.
Observation continues until Jan. 16. Here’s what you need to understand about the Quadrantids and other meteor showers.
What constitutes a meteor shower?
As Earth revolves around the sun, multiple times annually, it traverses through debris left by passing comets—and occasionally asteroids. The source of the Quadrantids is debris from the asteroid 2003 EH1.
When these swiftly traveling space rocks enter Earth’s atmosphere, the debris faces new resistance from the air and becomes intensely hot, ultimately leading to combustion.

At times, the surrounding air briefly illuminates, leaving a fiery streak—the conclusion of a “shooting star.”
You don’t require specialized tools to observe the diverse meteor showers that occur annually, just a location distant from city lights.
How to observe a meteor shower
The optimal time to view a meteor shower is during the early pre-dawn hours when the moon is positioned low in the sky.
Competing light sources—such as a bright moon or artificial illumination—are the primary impediments to a clear observance of meteors. Cloudless nights when the moon is at its smallest are ideal for watching.
And keep glancing upward, not downward. Your eyes will be better equipped to detect shooting stars if you refrain from checking your phone.
The Quadrantids will reach their peak on a night with a narrow crescent moon, just 11% full.
When is the upcoming meteor shower?
The forthcoming meteor shower, the Lyrids, will peak in mid-April.
