Solar system is a system of planets orbiting around a star, the Sun. Among those planets is our Earth. The solar System consists of the sun and of celestial bodies held by solar gravity. The mass of the sun is about 330 000 times the mass of the earth and makes up 99.8% mass entire solar system. The diameter of the sun is 1 400 000 km, i.e. about 109 Earth diameters. In the solar system except the sun is made up of eight planets, over 150 moons, and small bodies such as asteroids, comets and meteors.
In order of proximity to the Sun, the eight planets are mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
To measure distances in the solar system is used “astronomical unit” (AU). One AU corresponds to the distance from the earth to the Sun. Thus, the distance of one AU is nearly 150 million kilometers. For example, Jupiter rotates on its orbit 5.2 AU, i.e. the distance from the Sun is 5.2 times larger than the Earth. Continue reading
The science of studying celestial bodies and the Universe, astronomy . is one of the most important, since the beginning of time and reveals the secrets of our planet, Solar system and the Universe. The solar system consists of the Sun and many other celestial bodies that revolve around the Sun. It is located in Orion, one of the outer arm of the milky Way galaxy . the sleeves of these zones, which are characterized by a low density of matter.
What is in our Solar system?
In our solar system, you can find the planets mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, and their satellites.
In the beginning, people thought that our planet Earth is in the center of the Universe, and the Sun, the stars revolve around the Earth. Copernicus, born in 1473, was the first person who proved that the Earth together with other planets of our solar system revolve around the Sun. Continue reading
The planets and moons in orbit of the Sun
The largest planet in the Solar system. this is a Jupiter belonging to the class of gas giants. Ancient astronomers were able to detect and assign a very unusual name this planet. Named in honor of one of the most revered Roman gods, Jupiter is not in vain was honored to be the namesake of the thunder gods. For large-scale weather events, continuously produced in the atmosphere of the giant, strength and scale can outdo the deeds of the most powerful gods! Imagine the worst stormy weather on our planet. And now imagine the same thing, but only 10 times more intense and more powerful. These horrific lightning strikes, as if the gods went crazy and wants to destroy everything. Wild, wild the storm that engulfs everything in its path, and sometimes of centuries.
Jupiter is not alone in its orbit, having 67 different dimensions of the satellites. Like any ordinary giant planet has attracted much attention of scientists. A lot of research spacecraft was sent to Jupiter during the long years of study. Periodically, during the great opposition, Jupiter looks like the brightest star in the heavens. In this period of time activates the monitoring planeteurodisco ground-based and orbiting telescopes. Continue reading
