Planets of the solar system.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

A planet is a celestial body that must satisfy four conditions:

1. the body must revolve around the star (for example, around the Sun);

2. the body must have sufficient gravity to have a spherical or similar shape;

3. the body should not be near its orbit of other large bodies; Continue reading

Interesting facts about comets

Comets are small Solar system objects that move in orbit around the Sun and can be observed as a bright point with a long tail. They are interesting for several reasons.

Since ancient times people have observed comets in the sky. Only once in 10 years, we can see the comet from Earth with the naked eye. Its impressive tail flashes across the sky for several days or weeks.

In ancient times comets were considered a curse or a sign of previous trouble. So in 1910, when the Ground caught the tail of Halley’s comet, some entrepreneurs took advantage of the situation and sold people masks, pills from the comet, as well as umbrellas to protect from comets.

The name of the comet received from the Greek word for “long-haired” because people in Ancient Greece thought that comets look like stars with flowing hair.

Comets tail appears only when they are close to the Sun. When they are far away from the Sun, comets are extremely dark, cold, icy objects. Ice body is called the nucleus. Continue reading

On the outskirts of the Solar system walk comets

Some comets, rotating now in the Solar system, were originally in other star systems and ended up here due to the fact that the Sun is their “kidnapped”.

To this conclusion came a group of astronomers from the North-West research Institute in USA.

“If the results of our models and calculations are correct, then many comets that are present now on the outskirts of the Solar system originally was not here,” says scientific specialist of the Institute’s Hal Levison.

From his point of view, a significant proportion of comets that are now in the zone of the Solar system known as the Oort Cloud is aliens from other star systems.

“We know that stars are formed in clusters. Sun was born inside a huge community of other stars that were formed from a single cloud of gas and dust. In this cluster the stars were so close to each other that were able to “steal” different objects, such as comets through its gravity,” he says. Continue reading

Flight along cosmic strings
So far the only scientifically proven the possibility of interstellar travel is the acceleration of the spacecraft up to relativistic speeds (punctures and convolution space still remain purely speculative projects).…
