This service provides the physical and dynamical characteristics of
natural satellites in the Solar System: size, mass, rotational
properties, magnitude and albedo, orbital elements. These quantities
are taken from various publications listed under the bib_reference
parameter. These data will be updated as new values are published.
This service provides a compilation of spectra of asteroids in the
visible and NIR range. It is composed of various libraries distributed
as VizieR catalogues. Reformatted VOtable or fits versions are
provided with thumbnails. Ephemeris data are retrieved from Miriade
(IMCCE) for the reference date when possible.
This service provides a compilation of global spectra of planets and
satellites in the visible and NIR range, for quick reference purpose.
It is made from various libraries, including the
Tohoku-Hiroshima-Nagoya Planet Spectra Library (Lundock et al 2009)
and spectra from a USGS web site (R. Clark). Reformatted VOtable
versions are provided together with links to the original data.
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 gravity 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.
