Solar system

Theories, how did the Solar system . a great many. The first of them was the famous theory put forward by German philosopher Immanuel Kant in 1755. He believed that the origin of the solar system originated from some primordial matter, before that it was scattered freely in space.

One of the later cosmogonic theories is the theory of “catastrophes”. According to it our planet Earth was formed after some outside interference, for example, meeting the Sun with another star, this bout could cause the eruption of a certain part of the solar substance. Due to the filament of gaseous matter sufficiently quickly cooled down and solidified, thus forming a number of small solid particles, their accumulation was a sort of germ of the planets.

Planets of the solar system

The Central body in our system is the Sun. Refers to the stars, belongs to the class yellow dwarf. The sun is the most massive object of our system of planets. The closest location to the Earth star and the main body in our planetary system. In our system, the planets more or less common. No, for example, black planets. almost does not reflect light. Images of planets are often used in interior signage .

The first planet from the Sun in our Solar system is mercury – she is also on razmerami small planet of terrestrial group (in addition to her Land and include mercury Mars and Venus).

Further, the second, is Venus. Followed by the Earth is the shelter of all mankind. Our planet has a satellite – the moon that is easier to Land almost in 80 times. The moon is the only satellite of the Earth rotating around the Earth in an orbit. After the Sun it is the brightest object in the sky.The fourth planet is Mars is a desert planet has two satellites. Followed by a large group of planets is the so – called giant planets.

The sun and other planets played an important role in different religions. There were many religions, which worshipped the Sun. And astrology, studying the effect of planets on humans, and now affects many people. Earlier astrology was considered a science, but nowadays many consider it a superstition .

The largest and most massive of all giants is Jupiter, he represents our Solar system in miniature. Jupiter has more than 40 satellites, the largest of them is Ganymede, IO, Europe, Callisto. These satellites are also called Galilean, after the man who discovered them — Galileo Galilei.

Followed by the giant planet Saturn, many people know her because of her gorgeous rings. Saturn has 22 satellites, the largest seven – Dion, Mimas, Titan, Enceladus, Rhea, yapetus ocean, Tethys.

Followed by the giant planet Uranus – it is unusual in that it has the “lying on side” – that’s why Uranus is quite a sharp change of seasons. Has 21 satellites and a distinctive feature in the form of rotation in the opposite direction.

Past the giant planet is Neptune (the largest of Neptune’s satellite Triton). All giant planets have a distinctive feature in the form of a plurality of satellites, and a system of rings.

But the farthest and last planet in the Solar system is Pluto, it is also the smallest planet in our system. For Pluto has one satellite, Charon, he’s a bit less of the planet itself.
