Newton's Laws - Atoms and Light Formation of the Solar System What are some interesting features of the solar system as a whole? Nearly all the mass is at the center, in the Sun (99.9%) All of the planets orbit the Sun in the same direction. Nearly all of the Moons orbit their planets in that same direction (only notable exception: Triton, a Moon of Neptune) Nearly all of the planets rotate on their axis in that same direction (exception: Uranus, whose axis is at right angles to that of the ecliptic) All the planets, amd many of the Moons have orbits which are nearly circular. The four inner planets are rocky and relatively small (terrestrial) The four outer planets are much larger and mostly made up of gas (gas giants) Smaller rocky bodies (asteroids) are mostly confined to a belt between

Unformatted text preview: the planets Jupiter and Mars Icy bodies are found far beyond the gas giants in something called the Oort Cloud. They are not confined to the planet of the ecliptic, but instead form a spherical cloud around the Sun The Sun produces nearly all of the heat and light in the solar system The solar system is very large and empty. The planets are tiny compared to the distances between them. Each system of Moons mimics the Solar System to some extent in that the planet is much larger than the Moons which orbit it. The exception is the Earth-Moon system. Do these observed facts provide a clue to how the solar system was formed? Nebular Hypothesis...
