• Origin of Phenomenon: The Perseid meteor shower originates from Earth’s passage through debris consisting of ice, rock, and dust, shed by Comet Swift-Tuttle.
• Orbital details: This comet, with an orbital period of 133 years, last illuminated the skies in 1992 and will not grace Earth’s vicinity until 2125, as confirmed by NASA.
• Historic Discovery: Astronomers Lewis Swift and Horace Tuttle discovered Comet Swift-Tuttle in 1862, laying the foundation for understanding this celestial spectacle.

Its occurrence

• Annual Affair: A time-honoured spectacle, the Perseids meteor shower reaches its zenith every mid-August, enchanting both astronomers and laymen with its celestial display.
• Residual Cosmic Debris: The Perseids meteor shower unfolds as our planet intersects the path of cosmic remnants cast adrift by Comet Swift-Tuttle. This cosmic cloud spans approximately 27 km in width.
• Dazzling Cascade: Amidst this cosmic choreography, a breathtaking scene emerges as Earth encounters these fragments. During the peak, between 160 and 200 meteors elegantly streak through the atmosphere each hour, leaving behind a luminous trail of splendour.
• Speed and Splendor: Travelling at a staggering speed of around 214,000 km per hour, these meteors ignite a fiery display as they disintegrate nearly 100 km above the Earth’s surface.

What are Meteoric Showers?

• Cosmic Origins: Meteors, fragments of rock and ice, are expelled from comets during their celestial orbits around the sun. The Earth’s atmosphere heats these space rocks as they descend, leaving luminous streaks of gas in their wake.
• A Symphony of Debris: Meteor showers unfold when our planet traverses the debris trail left behind by comets or asteroids during their celestial journey. A cascade of meteorites gracing the skies in unison constitutes a meteor shower.
• Celestial Tapestry: NASA’s records attest to the existence of over 30 meteor showers annually, painting the skies with celestial beauty observable from our terrestrial vantage point.
