Short Definition: Solar system is the planetary system
consisting of the Sun and other celestial objects which are gravitationally
bounded with the Sun, located in an outer spiral arm of the Milky Way galaxy.
Detailed Definition: The Solar system formed 4.6 billion years ago
from the solar nebula. The mass of the Solar system is unevenly distributed. The Sun
weights 99,86 % of the all masses in the system. The rest of it falls on the
planets, dwarf planets, moons, asteroids etc. The Solar System is divided into 2
parts: the Inner Solar System (Mercury, Venus, Earth, Mars) – terrestrial planets
composed of rock and metal and Outer Solar System (Jupiter, Saturn, Uranus,
Neptune) – giant planets. The first two are gas giants (composed of hydrogen and
helium), and the next two are ice giants (composed of water, ammonia, and methane).
Between the inner and outer system is an asteroid belt with Ceres (dwarf
planet). It is assumed that the asteroid belt has been created in a collision
of a planet and celestial object. Behind the Neptune there is a Kuiper belt –
similar to asteroid belt with Pluto, Charon and Eris (dwarf planets).
Etymology: solar – Latin – solis - Sun system – Greek – systema - set of entities
that interact in an orderly and organized fashion
Sample Sentence(s): The solar wind emanating from the Sun blasts through the Solar System, interacting with the planets, and pushing material out into interstellar space.
