The applet below shows the orbits and positions of the planets right now . Click and drag your mouse to tilt or rotate the solar system. Shift+Click zooms in and Ctrl+Click zooms out. Note: The orbits of the planets are shown to scale, but the sun and planets themselves are much larger than scale so you can see them easily. The inner planets (Mercury, Venus, Earth, and Mars), are relatively small and made primarily of rock and iron. The asteroids orbit the sun in a belt beyond the orbit of Mars, tumbling and sometimes colliding with one another. Made mostly of rock and iron, the asteroids may be the remnants of a planet that never formed. The outer planets, with the exception of Pluto, are much larger and made mainly of hydrogen, helium, and ice. Many astronomers believe that Pluto was an interstellar wanderer that was captured by the Sun's gravity and was not an original part of the solar system. The planets move around the sun in fairly circular orbits (i.e., they are elliptical orbits with low eccentricity) Use your mouse to click and drag on the solar system above until you are looking straight down on the planets' orbits. Now zoom in and out to see how all the orbits are very circular, except for Pluto's!

Solar System - Celestial Mechanics Franz Heeke - Muenster/Germany A fluid in a glass rotates, when eccentrically shaken. My hypothesis: such "shaker effects" play an important role in celestial mechanics, driving and controlling the rotation of sun and planets. The mechanism of interaction is described in following Article 2. "Shaker effects" are most probably of influence also on our weather and climate. Eine Fluessigkeit in einem Glas rotiert, wenn sie exzentrisch geschwenkt wird. Meine Hypothese: "Schwenkeffekte" dieser Art spielen eine bedeutende Rolle in der Himmelsmechanik. Sie treiben und steuern die Rotation der Sonne und Planeten, und beeinflussen sehr wahrscheinlich auch unser Klima. Die vermutete Wirkungsweise ist in deutscher Sprache im Artikel 3 beschrieben.

The Solar System Listen What is the solar system? It is our Sun and everything that travels around it. Our solar system is elliptical in shape. That means it is shaped like an egg. The Sun is in the center of the solar system. Our solar system is always in motion. Nine known planets and their moons, along with comets asteroids , and other space objects orbit the Sun. The Sun is the biggest object in our solar system. It contains more than 99% of the solar system's mass Astronomers think the solar system is more than 4 billion years old.

The Solar System The words " solar system " refer to the Sun and all of the objects that travel around it. These objects include planets, natural satellites such as the Moon, the asteroid belt, comets , and meteoroids . Our solar system has an elliptical shape and is part of a galaxy known as the Milky Way. The Sun is the center of the solar system. It contains 99.8% of all of the mass in our solar system. Consequently, it exerts a tremendous gravitational pull on planets, satellites, asteroids, comets, and meteoroids. Astronomers believe the solar system formed 4.5 billion years ago. However, they differ in their beliefs about how the system formed. Some believe the whole solar system formed from a single flat cloud of gas, while others believe it formed when a huge object passed near the Sun, pulling a stream of gas off of the Sun. Astronomers theorize the planets then formed from this gas stream.
