Meteor showers occur when the earth’s orbit and that of a comet intersect. Figure 2: This is a composite infrared image of fragments from Comet 73P/Schwassman-Wachmann 3 captured by the Spitzer Space Telescope. cluster in various parts of the sky, their occurrence is sporadic – Observational records for it date back to 687 BC. For more info, read our meteor shower guide. temperature of the comet is about 47 degrees above absolute zero (-375 F). is the Field Guide to the San Andreas Fault. This usually occurs within the mesosphere, typically at a height of about 80km. Meteor showers can happen on a regular annual basis when the Earth passes through a path where a comet has left a trail of debris. This is why meteor showers are predictable annual events. A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky.These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. This is why meteor showers are predictable annual events. Andrewmeda.
