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 ...
Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary ...
Formation and evolution of the Solar System. Artist's conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun, while the rest ...
The Solar System is one of many planetary systems in the galaxy. [1] [2] The planetary system that contains Earth is named the "Solar" System. The word "solar" is derived from the Latin word for Sun, Sol (genitive Solis). Anything related to the Sun is called "solar": for example, stellar wind from the Sun is called solar wind.
Scratch is a high-level, block-based visual programming language and website aimed primarily at children as an educational tool, with a target audience of ages 8 to 16. [8] Users on the site can create projects on the website using a block-like interface. Scratch was conceived and designed through collaborative National Science Foundation ...
Historical models of the Solar System. Approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's.
The Solar System School offers a three-year course of study emphasizing actual research. The curriculum covers the entire area of the Solar System from small bodies to the planets and the Sun. The goal is a broad, interdisciplinary, and solid scientific education, extended with courses in numerical physics, space technology, project management ...
English: This 10 billion to 1 scale model of the Solar system can be placed into hallways of most school buildings. The inner solar system can be placed inside, while some or all of the the outer planets are typically placed outside, with Neptune at a distance of 450 meters from the Sun. Students can copy the drawings by hand on index cards or cut them out and glue or tape to the cards.
