LYRID METEOR SHOWER

25th April, 2023 Science and Technology

Disclaimer: Copyright infringement not intended.

Context

  • The Lyrid meteor shower occurs between April 16-25 every year and will peak on the night of April 22, 2023.

Details

  • The radiant of the meteor shower is located in the constellation Lyra, near its brightest star, Vega.
  • The peak of the shower is typically around April 22 each year.
  • The source of the meteor shower are particles of dust shed by the long-period Comet C/1861 G1 Thatcher.
  • The April Lyrids are the strongest annual shower of meteors from debris of a long-period comet, mainly because as far as other intermediate long-period comets go (200–10,000 years), this one has a relatively short orbital period of about 415 years.
  • The Lyrids have been observed and reported since 687 BC; no other modern shower has been recorded as far back in time.

Where do the meteors come from?

  • 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 where they disintegrate to create fiery and colorful streaks in the sky
