What Causes the Leonid Meteor Shower
The Leonid meteor shower is an annual event that occurs when the Earth passes through the debris trail of the Tempel-Tuttle comet. The comet is made up of ice and dust, and as it travels around the sun, it sheds dust and small particles. When these particles enter the Earth’s atmosphere, they burn up and create streaks of light in the sky. The Leonids are named after the constellation Leo, which is the point from which they appear to originate. The shower occurs every year in mid-November, and it is one of the most reliable and predictable meteor showers of the year.
History of the Leonid Meteor Shower
The Leonid meteor shower has a rich history dating back centuries.
Ancient Observations:
- Greek astronomer Aristides observed the Leonids in 902 BC, describing them as "raining like flakes of snow."
- Chinese astronomers recorded the Leonids in 687 BC and 36 AD, noting their radiant point in the constellation Leo.
Medieval Period:
- The Leonids were named "Leonis meteors" in the 10th century by the Arab astronomer Al-Battani.
- In 934 AD, an exceptionally bright Leonid display was observed over Europe.
19th and 20th Century:
- In 1833, astronomers began studying the Leonids scientifically.
- The Leonids reached their maximum activity in 1833, producing an estimated 100,000 meteors per hour.
- In 1866, Giovanni Schiaparelli identified the parent body of the Leonids as the comet Tempel-Tuttle.
21st Century:
- The Leonids continue to be an active meteor shower, with notable displays in 2001 and 2002.
- In 2019, the Leonids produced a stunning display with estimated rates of 15,000 meteors per hour.
- The Leonids are expected to remain an active meteor shower for centuries to come.

Supermoon During Leonid Meteor Shower
During the night of November 17-18, 2022, observers witnessed a spectacular astronomical event as the full moon coincided with the annual Leonid meteor shower. This celestial pairing created a dazzling display in the night sky.
The supermoon, appearing 14% larger and 30% brighter than an average full moon, bathed the Earth in a brilliant glow. This illumination made it more challenging to spot meteors, which generally peak at around 15 per hour during the Leonid shower. However, some observers managed to catch glimpses of the fiery streaks as they pierced the moonlit sky.
Despite the supermoon’s interference, the Leonid meteor shower still offered a captivating spectacle, with meteors radiating from the constellation Leo. Many observers reported seeing bright, colorful meteors, leaving lingering trains in their wake.
Impact of the Supermoon on the Leonid Meteor Shower
The supermoon, a full moon that is closest to Earth in its orbit, can have a significant impact on the Leonid meteor shower, which occurs annually in November.
- Reduced visibility: The bright moonlight from the supermoon makes it harder to observe faint meteors, reducing the apparent number of meteors visible. In 2020, the supermoon coincided with the peak of the Leonid shower, resulting in a decrease of up to 80% in visible meteors.
- Increased meteor activity: Despite reduced visibility, supermoons can also trigger increased meteor activity. The gravitational pull of the supermoon can disturb the Earth’s atmosphere, causing a rise in atmospheric drag. This drag can lead to a greater number of meteors entering the atmosphere and creating visible streaks.
- Shift in peak timing: The supermoon’s gravitational influence can also affect the timing of the meteor shower’s peak. The extra atmospheric drag caused by the supermoon can slow down the meteors, potentially delaying the peak of the shower.
Distinguishing Meteors from Stars
Appearance:
- Meteors: Brief streaks of light that appear for a few seconds and then vanish.
- Stars: Fixed points of light with a steady brightness.
Motion:
- Meteors: Move rapidly across the sky, often leaving a trail behind them.
- Stars: Appear stationary in the night sky.
Origin:
- Meteors: Small pieces of celestial debris (e.g., dust, asteroids) entering Earth’s atmosphere and burning up.
- Stars: Hot, gaseous celestial bodies that emit their own light through nuclear fusion.
Color:
- Meteors: Typically white, yellow, or green, depending on their composition.
- Stars: Vary in color from blue to red, based on their temperature.
Duration:
- Meteors: Last for a few seconds to several minutes.
- Stars: Shine continuously, often for millions or billions of years.
Identifying Meteoroids during the Leonid Meteor Shower
The Leonid meteor shower occurs when Earth passes through the debris trail of Comet Tempel-Tuttle. During the peak of the shower, observers can see dozens of meteors per hour. To identify meteoroids during the Leonid meteor shower, look for:
- Bright streaks of light: Meteors appear as bright streaks of light moving across the sky.
- Leave a trail: Meteors often leave a glowing trail that can persist for several seconds.
- Appearing across the sky: Meteors can appear anywhere in the sky, but they will all appear to radiate from the constellation Leo.
- Visible at night: The Leonids are best viewed late at night, when the sky is darkest.
Scientific Research on the Leonid Meteor Shower
Scientific research on the Leonid meteor shower has been ongoing for centuries, providing valuable insights into its characteristics and origins. Observations using telescopes and other instruments have revealed that:
- Duration and Intensity: The Leonid meteor shower occurs annually from November 14th to 21st, with peak activity typically between November 17th and 18th. The shower’s intensity varies from year to year, with occasional periods of exceptional activity known as meteor storms.
- Radiant Point: The meteors appear to originate from a single point in the constellation Leo, known as the radiant point. This suggests a common parental body that produced the meteoroids.
- Parent Body: The Leonids are associated with the comet Tempel-Tuttle, which orbits the Sun every 33.2 years. When Tempel-Tuttle passes near Earth, it releases dust and debris that create the meteor shower.
- Orbital Properties: The meteoroids that produce the Leonids have highly elliptical orbits with periods ranging from 33 to 114 years. Their orbits intersect Earth’s orbital path, leading to the annual meteor shower.
- Composition: Meteoroids associated with the Leonids are primarily composed of rocky material. Analysis of meteorites retrieved from the shower has shown that they contain minerals such as olivine, pyroxene, and plagioclase.
