| Description: | The Orionids are members of a meteor shower that occurs throughout October into early November. At its peak around October 21-22, as many as 60 meteors per hour can be seen apparently originating from its radiant located in the constellation Orion near its border with Gemini. Unlike some showers, Orionids can be seen several days before and after the peak night of October 21-22 (with a frequency of approximately 5-10 per hour).
The parent body of the Orionids is the famous Halley's Comet (source: Wikipedia). The meteor in this images appeared during a 90-minute exposure of IC443, the Jellyfish nebula, on October 20, 2007. Its bright green trail is pointing exactly towards Orion. When they hit the atmosphere the speed of the particles that cause these meteors is about 65 km/s. |
