🌝🌎 The Solar system 🌎🌝

The Solar system is the gravitationally bound system of the sun and the object that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small solar system bodies. Of the objects that orbit the Sun indirectly- the natural satellite- two are larger than the smallest planet, marcury. 
               The sun and planets

The solar system  formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the sun, with the majority of the remaining mass contained in jpiter. The four smaller inner system planets, mercury, venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer system planets are gianat palnets, being substantially more massive than the terrestrials.The two largest planets, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium ; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting point compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All eight planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.
