Here you can find surprising information of world beyond us. How does all perfect dynamics work to held us together. This site provides information related to the orbits, physical characteristics, and discovery circumstances for most known natural bodies in orbit around our sun.
High-precision ephemerides with custom selected observing parameters are available using our HORIZONS system.
Orbit diagrams for most solar system bodies as well as tables of orbital elements for the planets, planetary satellites, asteroids and comets are available.
Selected physical characteristics of the planets, planetary satellites, and some small-bodies are available.
It provides measurement regarding study astronomical bodies.
For many solar system bodies, discovery circumstances such as date, location, and discoverers are available.
Physical Data & Dynamical Constants
Selected physical characteristics of planets, planetary satellites, comets and asteroids are available.
High precision ephemerides for solar-system bodies are available on-line using JPL's HORIZONSsystem. Most optical and radar observers will be best served by using our HORIZONS system to generate custom observer-table ephemerides. Our on-line HORIZONS system can also be used to output ephemerides in the form of. . .
Below are diagrams of the planets, asteroids, and comets showing the inner solar system (out to the orbit of Jupiter), the outer solar system (just beyond Pluto), and the distant solar system. There are two diagrams for each region: one showing. . .
