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.

Accurate positions of small bodies can be obtained from our Horizons ephemeris system which uses a numerically integrated high fidelity model which includes gravitational perturbations by the Sun, all the planets, and some of the largest asteroids. The orbit viewer is limited to dates between 1600-01-01 and 2200-01-01. Orbit Paths

The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc .

Visualize orbits, relative positions and movements of the Solar System objects in an interactive 3D Solar System viewer and simulator.

Orbit Viewer 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.

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.

As part of our charter, we provide orbits and ephemerides for all known natural objects in our solar system. The Horizons service normally provides the latest orbit and most accurate ephemerides for any given object.

Our solar system takes about 230 million years to orbit the galactic center. 6. Spiraling Through Space. The Milky Way is a barred spiral galaxy. 7. Diverse Atmospheres. Our solar system has many worlds with many types of atmospheres. 8. Ring Worlds. The four giant planets – and at least one asteroid – have rings. 9. Getting Out There.

2020年3月20日 · A collection of visualizations of orbits for planets of our Solar System over the time range from 2020 to 2030. Useful for general discussions of the Solar System.

Of the eight major planets, Venus and Neptune have the most circular orbits around the Sun, with eccentricities of 0.007 and 0.009, respectively. Mercury, the closest planet, has the highest eccentricity, with 0.21; the dwarf planet Pluto, with 0.25, is even more eccentric.
