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 to Mars

“In 80 days around the world” – was the slogan in the old history of the development of technology. Now this task is formulated so: to achieve 40 days of the planet Mars. It sounds unbelievable, nonetheless it is quite real.

New rocket technology must already exist!

Firm Ad Astra Rocket Company earlier NASA astronaut Franklin Chang-Diaz has developed a new rocket engine. Thus the electric energy and the magnetic field associated to the plasma that goes with a high fever. This beam plasma produces uniform and efficient cravings and needs in comparison with other types of engines only in a small amount of fuel.

With this new technology significantly increased the likelihood that a manned mission will continue to be our neighboring planet about 40 days is a small revolution in space flight.

The smallest distance between Mars and Earth is about 56 million km, the largest 401 million km. 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
