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

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). The ship may abandon astronauts in suspended animation for a dozen or even a hundred light years and return them to Earth. But because of the relativistic slowing of Board time on earth will pass away not even the century and Millennium — and it is somehow not pleasing. In addition to other galaxies to get to, there’s no cryostasis will not help. But it is possible that the output is still there.

For 15 years Professor of theoretical physics at Imperial College London, Joao Magueijo develops the hypothesis of variable speed of light (Varying Speed of Light, VSL). However, he minded very little, since most scientists believe this idea is pure nonsense. But we are talking about science impossible, so will try to temper my skepticism.

VSL-models calculated in several ways. They all say that measured on Earth the speed of light in a vacuum is not an absolute constant, and only the lower limit of the speed of propagation of electromagnetic waves. In certain (frankly, vesimaailma) conditions may be many times 299 792 km/s. 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

The origin of the solar system
The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence…
