The planets today shows you where the planets are now as a live display - a free online orrery. In this solar system map you can see the planetary positions from 3000 BCE to 3000 CE, and also see when each planet is in retrograde.
Visualize orbits, relative positions and movements of the Solar System objects in an interactive 3D Solar System viewer and simulator.
As you zoom out, the solar system's outer planets – Jupiter, Saturn, Uranus and Neptune – come into view. The date slider allows you to move forwards or backwards by a few months to see the motion of the planets along their orbits.
Explore the 3D world of the Solar System. Learn about past and future missions.
Our Sun is in a small, partial arm of the Milky Way called the Orion Arm, or Orion Spur, between the Sagittarius and Perseus arms. Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). It takes about 230 million years to complete one orbit around the galactic center.
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.
