NASA/JPL Eyes - Solar System Interactive
NASA’s Solar System Interactive (also known as the Orrery) is a live look at the solar system, its planets, moons, comets, and asteroids, as well as the real-time locations of dozens of NASA missions.
Planet Orbits - Space Facts
2015年11月18日 · In the time it takes the Earth to complete one orbit, the planets closer to the Sun (Mercury and Venus) orbit at least once. The more distant planets (Mars, Jupiter, Saturn, Uranus and Neptune) which move slower and have a greater distance to travel, complete just a fraction of their orbits in this time.
Solar System - Wikipedia
The largest objects that orbit the Sun are the eight planets. In order from the Sun, they are four terrestrial planets (Mercury, Venus, Earth and Mars); two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). All terrestrial planets have solid surfaces.

What are the orbital lengths and distances of objects in our solar …
The picture below shows the planets in their orbits on the orbital plane. You have to look carefully to see our home. The four inner planets (Mercury, Venus, Earth and Mars) are in the tiny disk in the center, inside of Jupiter's orbit.
Chapter 5: Planetary Orbits - NASA Science
You will be able to describe the general concepts and advantages of geosynchronous orbits, polar orbits, walking orbits, Sun-synchronous orbits, and some requirements for achieving them. An illustration of orbital parameters and elements.
Orbit Viewer - NASA
This tool shows approximate orbits of the planets and major planetary satellites. Optionally, one or more user-selected small body (asteroids and comets) orbit may also be shown. For help using this tool, select the Help item under the menu icon (below).
Orbits and Kepler’s Laws - Science@NASA
2024年5月2日 · Kepler's three laws describe how planets orbit the Sun. They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet’s orbital period is proportional to the size of its orbit.
Orbits & Ephemerides - NASA
Display the orbits of all the planets, planetary satellites, and optionally one or more small bodies. Links to ephemerides available for download.
Planetary Orbits & Ephemerides
The JPL planetary and lunar ephemerides Development Ephemeris (DE) series includes the positions of the Sun, the barycenters of eight planetary systems, the Moon, the Pluto system barycenter, and lunar libration angles, as well as their associated velocities.
