Why in News?<\/b><\/h2>\n

Orionid meteor shower is active from October 2 to November 7, 2026<\/b>, with its peak expected on the night of <\/span>October 21-22, 2026<\/b>. The annual meteor shower occurs when Earth passes through dust and debris left behind by <\/span>Halley\u2019s Comet<\/b>, producing bright streaks of light in the night sky.<\/span><\/p>\n

Orionid Meteor Shower<\/b><\/h2>\n

Orionid meteor shower is an annual celestial event that occurs when Earth passes through dust and debris left behind by Halley\u2019s Comet, causing particles to enter Earth\u2019s atmosphere and produce bright streaks of light.<\/span><\/p>\n

    \n
  • Origin: <\/b>The Orionids originate from dust and small rocky particles released by Halley\u2019s Comet as it travels around the Sun.<\/span><\/li>\n
  • Parent Comet: <\/b>The shower is associated with 1P\/Halley, commonly known as Halley\u2019s Comet, which returns to the inner Solar System approximately every 76 years.<\/span><\/li>\n
  • Radiant Point:<\/b> The meteors appear to originate from a point near the constellation Orion, which gives the shower its name. This apparent origin is called the radiant.<\/span><\/li>\n
  • Meteor Speed: <\/b>Orionid meteors enter Earth’s atmosphere at approximately 66 kilometres per second, making them among the faster annual meteor showers.<\/span><\/li>\n
  • Visibility:<\/b> The Orionids can be observed from both the Northern and Southern Hemispheres, including India, provided the sky is clear and dark.<\/span><\/li>\n
  • Meteor Rate: <\/b>Under ideal dark-sky conditions, observers may see around 10\u201320 meteors per hour near the peak. The actual number depends on moonlight, weather and light pollution.<\/span><\/li>\n
  • Best Time to Observe: <\/b>The hours after midnight and before dawn generally offer favourable viewing opportunities because the radiant rises higher in the sky.<\/span><\/li>\n
  • Observation Equipment: <\/b>A telescope or binoculars is not necessary. Observers can view the shower with the naked eye by choosing an open location away from artificial lights.<\/span><\/li>\n
  • Formation Mechanism:<\/b> When Earth crosses the comet’s debris stream, particles enter the atmosphere at high speeds and heat the surrounding gases, producing visible streaks of light.<\/span><\/li>\n
  • Relationship with Another Meteor Shower: <\/b>Halley\u2019s Comet is also responsible for the Eta Aquariid meteor shower, which generally peaks in early May. Both showers occur when Earth encounters different portions of the comet’s debris trail.<\/span><\/li>\n<\/ul>\n

    How is the Orionid Meteor Shower Formed?<\/b><\/h2>\n

    The Orionid meteor shower occurs when Earth passes through a stream of dust and rocky particles left by Halley\u2019s Comet during its repeated journeys around the Sun.<\/span><\/p>\n

    The process takes place in the following steps:<\/span><\/p>\n

      \n
    1. Comet releases debris:<\/b> As Halley\u2019s Comet approaches the Sun, it releases dust, rocky particles and gas from its nucleus.<\/span><\/li>\n
    2. Debris forms a trail: <\/b>These particles spread along the comet\u2019s orbit and remain in space.<\/span><\/li>\n
    3. Earth crosses the debris stream: <\/b>Every year, Earth passes through this trail during October.<\/span><\/li>\n
    4. Particles enter the atmosphere: <\/b>The particles enter Earth\u2019s atmosphere at very high speeds.<\/span><\/li>\n
    5. Light streaks appear: <\/b>Interactions with the atmosphere heat and excite the surrounding gas, producing bright streaks of light called meteors.<\/span><\/li>\n<\/ol>\n

      What is Halley\u2019s Comet?<\/b><\/h2>\n

      Halley\u2019s Comet, officially designated 1P\/Halley, is one of the best-known periodic comets in the Solar System. It is the parent body responsible for both the Orionid and Eta Aquariid meteor showers.<\/span><\/p>\n

        \n
      • Orbital period:<\/b> Approximately 76 years.<\/span><\/li>\n
      • Last appearance:<\/b> 1986.<\/span><\/li>\n
      • Next expected return:<\/b> 2061.<\/span><\/li>\n
      • Composition:<\/b> Primarily ice, dust and rocky material.<\/span><\/li>\n
      • Naming: <\/b>Named after English astronomer Edmond Halley, who recognised that several historical comet sightings were appearances of the same returning comet.<\/span><\/li>\n<\/ul>\n

        Important Terms Related to Meteor Showers<\/b><\/h2>\n

        Understanding the following terms is useful for astronomy and science-related questions.<\/span><\/p>\n

          \n
        • Meteor: <\/b>The streak of light produced when a space particle enters a planetary atmosphere and heats up.<\/span><\/li>\n
        • Meteoroid: <\/b>A small natural object travelling through space.<\/span><\/li>\n
        • Meteorite:<\/b> A fragment of a meteoroid that survives its passage through the atmosphere and reaches the ground.<\/span><\/li>\n
        • Meteor shower:<\/b> An event in which several meteors appear to originate from a common point in the sky.<\/span><\/li>\n
        • Radiant: <\/b>The apparent point in the sky from which meteors in a shower seem to emerge.<\/span><\/li>\n
        • Comet:<\/b> An icy body containing dust and rocky material that releases gas and dust when heated by the Sun.<\/span><\/li>\n
        • Fireball: <\/b>An exceptionally bright meteor.<\/span><\/li>\n
        • Periodic comet: <\/b>A comet that returns to the vicinity of the Sun at regular intervals.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
