2. Outline of the Solar System - Wikipedia

   en.wikipedia.org/wiki/Outline_of_the_Solar_System

   Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies.

3. Solar System - Wikipedia

   en.wikipedia.org/wiki/Solar_System

   The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...

4. Planetary mnemonic - Wikipedia

   en.wikipedia.org/wiki/Planetary_mnemonic

   A planetary mnemonic refers to a phrase created to remember the planets and dwarf planets of the Solar System, with the order of words corresponding to increasing sidereal periods of the bodies. One simple visual mnemonic is to hold out both hands side-by-side with thumbs in the same direction (typically left-hand facing palm down, and right ...

7. Heliosphere - Wikipedia

   en.wikipedia.org/wiki/Heliosphere

   Pioneer 10 was the first spacecraft to detect sodium and aluminum ions in the solar wind, as well as helium in the inner Solar System. [66] In November 1972, Pioneer 10 encountered Jupiter's enormous (compared to Earth) magnetosphere and would pass in and out of it and its heliosphere 17 times charting its interaction with the solar wind.

8. Formation and evolution of the Solar System - Wikipedia

   en.wikipedia.org/wiki/Formation_and_evolution_of...

   The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year, is in the range of 220–250 million years. Since its formation, the ...

9. Solar System belts - Wikipedia

   en.wikipedia.org/wiki/Solar_System_belts

   Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...
