The quiet celestial show occurring as the year winds down

Ursids Meteor Shower 2022 · 6:54 · Video: Learn the Sky · Watch at the source

In short: While most stargazers flock to the high-intensity Geminids, a subtler display awaits in late December. The Ursid meteor shower offers a more intimate look at our solar system's debris, providing a steady stream of shooting stars for those who prefer a tranquil night sky over a frantic celestial spectacle.

The Ursid meteor shower is an annual event that occurs from mid-December until the Winter solstice. It is categorized as a minor meteor shower because it is relatively low-producing compared to more famous displays like the Geminids. While the Geminids can reach maximum rates of 120 meteors per hour, the Ursids typically produce between eight and 28 meteors per hour. However, this frequency is not constant; history shows that the shower occasionally produces rare outbursts where dozens of meteors appear in a single hour.

The mechanics of the shower are tied to comet 8P/Tuttle. As Earth orbits the sun, it passes through the trail of debris left behind by this specific comet. To an observer on the ground, these meteors appear to originate from a single point in the sky known as the radiant. For the Ursids, this radiant is located within the constellation Ursa Minor, also known as the Little Bear.

Viewing conditions for the 2022 event were particularly favorable due to a new moon occurring on December 23. A new moon provides an ideal dark sky because it lacks the glare of a bright moon, allowing dimmer meteors to become visible. For those seeking the best view, the period just before dawn in the early morning hours of December 23 is recommended, provided the weather remains clear.

Despite its celestial beauty, the shower often faces terrestrial obstacles. In late December 2022, a pocket of Arctic air descended over the continental United States, bringing temperatures below 0 degrees Fahrenheit (-18 Celsius) in many regions. In some areas, such as the Midwest, blizzards can completely obscure the view, highlighting the constant interplay between astronomical events and local meteorology.
