WebbThe two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. On Earth, both hydrogen and helium are gases, so Jupiter and Saturn are sometimes called gas planets. But, this name is misleading. Webb3 feb. 2024 · Download Ephemerides. High precision ephemerides for solar-system bodies are available online using JPL’s Horizons system. Most analysis (including optical and radar observations) will be best served by using the Horizons system to generate custom observer-table ephemerides. The Horizons system can also be used to output …

[0807.1272] Dynamics of small bodies in planetary systems
WebbAbstract. All the giant outer planets of the solar system possess ring systems, each with an accompanying retinue of small satellites. Although the ring systems of Jupiter, Saturn, Uranus and Neptune have their individual characteristics, one property they share is that small satellites have played a rôle in determining their dynamical structure. WebbThe scattering of small bodies by planets is an important dynamical process in planetary systems. In this paper, we present an analytical model to describe this process using the … WebbPhysics of cosmic dust and small bodies in Solar system: comets, asteroids, Kuiper-Belt Objects .
