Perseid meteor shower (“the Perseids”)




Every year in early August, we can observe the Perseid meteor shower (“the Perseids”). And it’s a fascinating sky എവെന്റ്റ്‌.Every year in August, the Earth passes through rock and dust fragments left behind by the comet Swift-Tuttle, last time it came near the Sun. As these small particles collide with the Earth’s atmosphere, they burn-up, often creating a startling streak of light across the സ്കൈ.The term “Perseid”, refers to the star constellation of പെര്സയൂസ്.The meteors actually have nothing to do with the stars we see from Earth, as being part of Perseus. It just appears as though the meteors originate from Perseus.
In fact, the rock fragments are close to the Earth – that’s why they burn in our atmosphere.
They are very close, just a few hundred miles – not many, many light years distant like the stars.
But, if you trace-back the bright trails of meteors we see, they appear to originate from the stars of Perseus.
