4M Kidz Labs Solar System Planetarium Model

Product Information

The Solar System was formed 4.6billion years ago from the gravitational collapse of a giant interstellar molecular cloud. Over time, the cloud formed the Sun and a protoplanetary disk that gradually coalesced to form planets and other objects. That is the reason why all eight planets have an orbit that lies near the same plane. In the present day, 99.86% of the Solar System's mass is in the Sun and most of the remaining mass is contained in the planet Jupiter. Six planets and many other bodies have natural satellites or moons orbiting around them. All of the giant planets and a few smaller bodies are encircled by planetary rings, composed of ice, dust and sometimes moonlets.

Main article: Giant planet The outer planets Jupiter, Saturn, Uranus and Neptune, compared to the inner planets Earth, Venus, Mars, and Mercury at the bottom right The angular momentum of the Solar System is a measure of the total amount of orbital and rotational momentum possessed by all its moving components. [37] Although the Sun dominates the system by mass, it accounts for only about 2% of the angular momentum. [38] [39] The planets, dominated by Jupiter, account for most of the rest of the angular momentum due to the combination of their mass, orbit, and distance from the Sun, with a possibly significant contribution from comets. [38] Composition A solar system comprises of a star and all the celestial bodies that travel around it - planets, moons, asteroids, comets. Some solar systems may even have two stars.

B Dwarf planet positions are also shown - but it should be realised that these objects often rise far above and below the plane of the ecliptic. This is because their orbital planes are tilted with respect to the ecliptic - by more than 40 degrees in some cases. So be aware that just because the app may occasionally show a planet and a dwarf planet to be very close to each other in the plan view, they may, in fact, be separated by a large perpendicular distance. Earth's TiltGonggong (67.38AU average from the Sun) is another dwarf planet in a comparable orbit to Eris, except that it is in a 3:10 resonance with Neptune. [182] It has one known moon, Xiangliu. [183] Farthest regions Both apps show a solar system map - a "plan view" of the planets laid out in the plane of the ecliptic (the flat plane in which all the main planets move about the Sun). a b Ryden, Robert (December 1999).

The Sun is a population I star; it has a higher abundance of elements heavier than hydrogen and helium (" metals" in astronomical parlance) than the older population II stars. [85] Elements heavier than hydrogen and helium were formed in the cores of ancient and exploding stars, so the first generation of stars had to die before the universe could be enriched with these atoms. The oldest stars contain few metals, whereas stars born later have more. This higher metallicity is thought to have been crucial to the Sun's development of a planetary system because the planets form from the accretion of "metals".

Kirkwood gaps are sharp dips in the distribution of asteroid orbits that correspond to orbital resonances with Jupiter. [124] Asteroid moons are asteroids that orbit larger asteroids. They are not as clearly distinguished as planetary moons, sometimes being almost as large as their partners (e.g. that of 90 Antiope). The asteroid belt includes main-belt comets, which may have been the source of Earth's water. [125]a b Marochnik, L.; Mukhin, L. (1995). "Is Solar System Evolution Cometary Dominated?".
