The Leonids meteor shower is an annual astronomical event that occurs every year in mid-November when the Earth passes through the debris trail of the Tempel-Tuttle comet. The shower is named after the constellation Leo, which is the radiant point for the meteors.

The Leonids are known for their bright, fast-moving meteors, which can often produce spectacular streaks of light across the night sky. In 1833, the Leonids produced a meteor storm with an estimated 100,000 meteors per hour. While such intense storms are rare, the Leonids still offer a reliable and beautiful meteor shower for skywatchers.

Leonids Meteor Shower History

The Leonids meteor shower has been observed for centuries. The first recorded sighting of the shower was in 902 AD by Chinese astronomers. The shower is associated with the Tempel-Tuttle comet, which was discovered in 1865. The comet orbits the Sun every 33 years, and each time it passes close to the Sun, it releases a stream of dust and debris. When the Earth passes through this debris stream, the particles collide with the Earth’s atmosphere and create the Leonids meteor shower.

Other Leonid Meteor Showers

In addition to the annual Leonids meteor shower, there have been several other notable Leonid meteor storms throughout history. The most recent major Leonid storm occurred in 2001, when observers reported seeing up to 3,000 meteors per hour. Leonid meteor storms are typically caused by an increase in the density of the comet’s debris stream.

Leonids Meteor Shower History

The Leonids meteor shower has been observed for centuries. Ancient Chinese records mention a "great star rain" in 36 AD, and Arabic astronomers noted the shower in 902 AD. In 1002 AD, the shower was so intense that it was said to have "rained stars for three days and nights."

The Leonids are caused by the Earth passing through the debris trail of Comet Tempel-Tuttle. The comet orbits the Sun every 33 years, and when it passes close to the Earth, it sheds dust and debris. This material enters the Earth’s atmosphere at high speeds, burning up and creating the shooting stars that we see.

The Leonids are typically visible from mid-November to mid-December, with the peak of the shower occurring around November 17th. The best time to view the Leonids is on a clear, dark night, away from city lights.

Leonids Meteor Shower Folklore

The Leonids meteor shower has been associated with numerous legends and beliefs throughout history:

Tears of St. Lawrence: The most common folklore connects the Leonids to the martyrdom of St. Lawrence. Legend has it that the saint was burned alive on a gridiron on August 10th, and the meteors that appear around this date represent the tears of sorrow shed for his death.
The Great Deluge: Some cultures believed that the Leonids signaled the impending arrival of a great flood, similar to the biblical Noah’s Flood.
Fireflies from Heaven: In Japan, the Leonids were once referred to as "tenka-boshi" or "fireflies from heaven," as they were thought to be the spirits of the dead returning to Earth.
Souls of Warriors: In ancient Greece, the Leonids were associated with the souls of warriors who had fallen in battle.
Omens of War: In Western Europe, the Leonids were often seen as an omen of impending war or conflict.

Leonids Meteor Shower Science

The Leonids meteor shower is a yearly astronomical event that occurs when the Earth passes through the debris trail of the comet Tempel-Tuttle. As the comet’s ice sublimates, it releases particles that enter Earth’s atmosphere and burn up, creating the meteors.

The peak of the Leonids shower typically occurs on November 17th or 18th, with a maximum zenith hourly rate (ZHR) of around 15 meteors per hour. However, the ZHR can vary significantly from year to year, with occasional outbursts producing hundreds or even thousands of meteors per hour.

The Leonids meteor shower is known for its bright and colorful meteors, often leaving persistent trails in the sky. The meteors are typically yellow-orange in color and can be seen in all parts of the night sky, although they appear to radiate out from the constellation Leo.

The Leonids meteor shower has been observed for centuries, with the first recorded sightings dating back to the 10th century. The shower is named after the constellation Leo, which is the apparent radiant point of the meteors.

Meteoroids of the Leonids Meteor Shower

The annual Leonids meteor shower is caused by the Earth passing through a debris stream left behind by the comet Tempel-Tuttle. The shower’s meteoroids are composed of small fragments of rock and dust from the comet’s tail. These meteoroids are typically less than a grain of sand in size, and they disintegrate when they enter the Earth’s atmosphere, creating the familiar streaks of light known as meteors. The Leonids meteor shower is active from November 14th to the 21st, with a peak occurring around November 17th.

Stargazing Tips for Leonids Meteor Shower

Find a Dark Location:
