The Geminids are one of the brightest and most reliable annual meteor showers, peaking every year in mid-December.

Origin of the Name

• The meteor shower is named after the constellation Gemini, from where the meteors appear to radiate. This apparent point of origin is called the radiant. However, the constellation is only the direction in the sky - not the actual source of the meteors.

Time of Occurrence

• The Geminids occur every year in December, with peak visibility typically during the late-night and pre-dawn hours, when the radiant rises higher in the sky.

Parent Body – A Rare Case

• A unique scientific feature of the Geminids is their origin. Most meteor showers are produced by comet debris, but the Geminids originate from an asteroid called 3200 Phaethon. This makes the Geminids one of the very few major meteor showers linked to an asteroid rather than a comet.

Meteor Characteristics

• Geminid meteors are known for being bright and relatively slow-moving, which makes them easier to spot. They often produce multi-colored streaks in the sky due to the presence of different minerals that burn at different temperatures.

Understanding Meteors

• Meteors are caused by small space particles entering Earth’s atmosphere at very high speeds.
• A meteoroid is a small rocky or metallic object traveling in space. When it enters Earth’s atmosphere and burns due to friction, it produces a streak of light known as a meteor. If any part of it survives the journey and reaches the ground, it is called a meteorite.
• Meteor showers occur when Earth passes through trails of dust and debris left behind by comets or asteroids. These particles collide with the atmosphere and burn up, creating the visible streaks of light.

Why the Geminids Stand Out

The Geminids are considered special because they are linked to an asteroid instead of a comet, they produce a high number of bright meteors, and they are known for their consistent annual activity. Their slower speed compared to many comet-based meteor showers makes them especially visible and spectacular.
