Solar system

We fly up to the Sun

General idea: we arrived in the Solar system and the astronomical data reported by us correspond to the structure of this system, which is clear from the parameters of the Landing.

But what is this system?

Indeed, the Solar system looks specially designed: minor planets, suitable for life, under the guise of giants, attracting asteroids and comets.

If so, then the planet must be artificial.

We know nothing about them, except the Land on which the simulacra are.

Can a Land be so that we can see with our own eyes?

Alas, in theory it is impossible.

The earth rotates and each body acts on the centrifugal force. The total vector of this force and of gravity is directed to the equator:

On solid surfaces the friction force is quite compensates for this small vector. But in the ocean nothing can keep water from draining to the equator. Continue reading

Comet

Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.

Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.

The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:

Dust

Ice (water, ammonia, methane, carbon dioxide)

Some organic materials (e.g., resin)

Rocky ground (optional) Continue reading

What the comet was approaching the Earth

Events

A small comet Hartley 2 will be visible from Earth with the naked eye, on 20 October, when she will fly past the planet just 11 million kilometers. Over the last century, this will be the closest “contact” of our planet with a comet.

Hartley-2 was discovered in 1986. Its orbital path was far from the Earth, while the couple spins around Jupiter do not orbit drew closer.

Hartley-2 will be included in the number of comets that passed in the last century is quite close to the Earth.

Comet McNaught (McNaught) lit up the sky in 2007. Becoming the brightest comet in over forty years, McNaught was dubbed the great comet of 2007. The astronauts were able to observe this comet, resulting in Strait light on the composition of these celestial bodies. spacecraft Willis found here the decrease of the solar wind.

The comet’s discoverer, Australian astronomer Robert McNaught (Robert McNaught) was discovered in 2009 a new bright comet McNaught C/2009 R1 . flying past Earth in June of this year. Continue reading
