Our Solar System

Our solar system consists of its major star, the Sun and a set of body is not just about the eight planets now known, that because the August 24, 2006 the International Astronomical Union meet in Prague which was define planet or to be careful as such or the function of the sound "planet" Pluto was leaving because their individuality do not conform to what is intended by the planet, so going to be a planetoid and for that reason, our Solar System now includes nine planets, but eight, this termination is due to the amount of various bodies that have different sizes orbiting like planets around the Sun as asteroids, comets, meteoric bodies, interplanetary dust and gas, which make this set we call the solar system.

What is the Solar System?

The Solar System is a place or classification of planets orbit a common star (the Sun) which in revolve orbits virtually round method around the center of the galaxy. The 99.86% of the mass of the solar system is restricted in the Sun and most of the respite in Jupiter.

How did it?

Near are numerous theories about the configuration of our Solar System, one of which is the nebular theory:

It indicate that the solar system had formed from a nebula (cloud of gas and dust immense) that began to collapse upon itself due to gravitational forces which outnumbered own pressure forces the gases tend to that the nebula expands.

Types of nebulae

Credit to present telescopes and the use of computers, have been able to expand thorough digital photos, using suitable software, can be colored to obtain spectacular images. The most remarkable aspects of the nebulae are their variety of shapes and structures.

Planetary Nebulae

Planetary nebulae be similar to planets while viewed during a telescope.

Nebulae

The nebulae is more or less solid, evident or not from Earth. Nebulae can be found anywhere in the interstellar space. Before the invention of the telescope, the term nebula was applied to all celestial objects of diffuse appearance. As a result, many objects are now known to be star clusters of galaxies were called nebulae. Nebulae have been detected in almost all galaxies, including our own, the Milky Way. Depending on the age of stars associated, it can be classified into two groups: 1. - Associated evolved stars, such as planetary nebulae and supernova remnants. 2. - Associated with very young stars, some even still in the process of training, such as Herbig-Haro objects and molecular clouds.

Star clusters

Star cluster is a group of stars detained jointly since regards the result of gravitation. Star clusters are classified into two groups: open clusters, which have no definite shape, and globular clusters, which are spherical or nearly spherical. The open consist of a few hundred young stars, while globular clusters contain more than a thousand times that amount, and are generally very old stars. Globular clusters form a halo around our galaxy, the Milky Way, while the open is located in the spiral arms. Open clusters are much more numerous than globular: about 1,000 are known in our galaxy and there are only 140 globular.

What is the Milky Way?

Specification we could well see the Milky Way from external fettle, we would see the center bulky, bright yellow, shaped like a rugby ball, and a thin disk of blue revolving approximately. The Milky Way is a barred spiral, like a pinwheel. It is believed that the center is a black hole, which scientists call Sagittarius A. The center is not rounding, but rather elongated. Near him are the oldest stars, red and yellow.

 Instinctive hub four arms: Arm Peruses, Orion Arm, Arm Cross Arm Sagittarius and Centaurs. Form a slowly rotating disk in a spiral. In the arms are the youngest stars, White and Blue. There are also many nebulae where new stars form. The Sagittarius Arm is the brightest of all.

A trail in the sky of the Milky Way

On top of plain night we can see a colorless group cross-ways the sky from side to side, with many stars. This is only a small part of our neighbors. Mutually we structure the Milky Way. The Romans called "Milk Road" which means it is Milky Way in Latin.

The Milky Way of our galaxy

Our galaxies the solar system is one of the twisting weapons, about 30,000 light years from the center and about 20,000 from the end.
