Astronomy can make no distinctions between the orbit of a planet and the orbit of a satellite.
"Outlines of a Mechanical Theory of Storms" by T. Bassnett
The solar system for astronomy is not a bird's-eye view of elliptical orbits, with the planets and satellites in definite phases.

The discovery of the four chief satellites may be regarded as an important epoch in the history of astronomy.

New results on focusing of gamma-rays with Laue lenses
The introduction covers 2000 years of astronomy from Ptolemy to modern times. The Hipparcos satellite of the European Space Agency was the first satellite specifically designed for astrometry.
Astrometry during the past 2000 years
The window to the high-energy (> 30 MeV) gamma-ray cosmos has been open now for four decades, with measurements by OSO-3 satellite (Kraushaar et al. 1972) followed by the second Small Astronomy Satellite (SAS-2)(Fichtel et al. 1975) and the Energetic Gamma Ray Experiment Telescope (EGRET) (Sreekumar et al. 1998).
Inverse Compton Contribution to the Star-Forming Extragalactic Gamma-Ray Background
During the time before GLAST becomes operational, two initiatives in satellite-based γ -ray astronomy are planned to provide astronomical data at GeV energies.
For the ﬁeld of neutrino astronomy, the most crucial question is the SN rate in our own Milky Way because even the largest foreseen detectors will not reach beyond our galaxy and its satellites.
