Table information for 'meteor_showers.epn_core'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The ephemeris were produced by simulating the ejection of meteoroids from the sunlit hemisphere of cometary nuclei, typically from 0 to 3 au, followed by the propagation of orbits of meteoroids in the Solar System, taking into account the gravitation of the Sun, the 8 planets, Pluto, and the Moon, as well as the radiation pressure and the Poynting-Robertson drag. Note that asteroid parent bodies were considered as active (i.e. comet-like bodies) even if they are not active today. The showers are predicted when a planet enters a large enough set of meteoroids, at a distance less than typically 0.01 au. See Vaubaillon J., Colas F., Jorda L. 2005 A new method to predict meteor showers. I.
