Project Spain - Perseid Meteor Shower - August 2021
Meteors come from leftover comet particles and bits from broken asteroids. When comets come around the sun, they leave a dusty trail behind them. Every year Earth passes through these debris trails, which allows the bits to collide with our atmosphere and disintegrate to create fiery and colourful streaks in the sky.
The Perseids are the most popular meteor shower as they peak on warm August nights as seen from the northern hemisphere. The Perseids are active from July 17 to August 24. They reach a strong maximum on August 11 or 12, depending on the year.
Normal rates seen from rural locations range from 50-75 shower members per hour at maximum. The Perseids are particles released from comet 109P/Swift-Tuttle during its numerous returns to the inner solar system. They are called Perseids since the radiant (the area of the sky where the meteors seem to originate) is located near the prominent constellation of Perseus when at maximum activity.
The Perseids are considered the best meteor shower of the year. With very fast and bright meteors, Perseids frequently leave long "wakes" of light and colour behind them as they streak through Earth's atmosphere. Perseids are also known for their fireballs. Fireballs are larger explosions of light and colour that can persist longer than an average meteor streak. This is due to the fact that fireballs originate from larger particles of cometary material. Fireballs are also brighter, with apparent magnitudes greater than -3.
