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

Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

Open planet in honour of Day of Astronautics

One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.

Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.

The asteroid Vesta, around the Main asteroid belt

In earth time: 1938

Discoverer: Isaac Asimov, “In the thrall of Vesta”

What happens:

Three space travellers, survivors in the crash of a spaceship. Three airtight rooms, one spacesuit, three days ‘ supply of oxygen, a week’s supply of food and a year’s supply of water… Continue reading
