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 comet’s coma or head of the comet . is a fuzzy mist surrounding the actual nucleus of the comet. Including the tail, the coma is all we actually see, watching the comet from the Earth.
The shape and structure of the comet’s coma
The shape of the coma can vary from comet to comet and for the same comet during its passage, depending on its distance from the Sun and the corresponding quantities of dust and gas. Pale or bright comets producing little dust and often have a round shape, and comets that produce a significant amount of cometary dust have fan-shaped or parabolic shape.
This is due to released different-sized dust grains: those that are bigger are moving to the left along the trajectory of a cometary orbit, and the smaller particles are repelled from the Sun using light pressure.
Coma has 2 main components: gas-shell and shell dust. In fact, scientists believe that comets produce almost the same amount of gas and dust. Continue reading
We present to your attention a fantastic audio recordings of space missions Voyager I and II launched in 1977. These unmanned space probes that are flying for 37 years away from our planet and, according to scientists who have already left our solar system.
During this flight they had studied the planet all around us, the study.
Now about our atmosphere and the sounds of the planets.
As everyone knows, in space there is no sound. Presents the atmosphere of electromagnetic vibrations of the planets, their moons and moons, planetary magnetosphere and the solar wind. Such a complex interaction and created sound vibrations that we can hear. They sound very interesting, sometimes even creepy.
Now I want to tell you a little interesting information about each planet in our Symphony.
Jupiter is the largest planet in the Solar system, a gas giant. The diameter of Jupiter is approximately 11.2 larger than the earth. Continue reading
