The earth is the home of humankind. Can be considered and the Solar system. After all, we already went to the moon, our spacecraft has reached other planets. It would seem that about the area of Land we need to know everything.
Actually mankind for decades trying to unravel such close and such mysterious phenomena. Describe below of the top ten mysteries of the Solar system.
The Oort Cloud. The main issue regarding this site is that whether there is any? This is perhaps the chief mystery of our Solar system. Scientists have suggested the existence of clouds only hypothetically, but this piece of the Universe no one has seen. The theories then formed comets with long orbital period. Scientists can only assume that the Oort cloud is at a distance of 50-100 thousand.e. from the Sun. The bounds of this object lying on the very edge of the Solar system. The billions of bodies are from the cloud is bound by gravity to the Sun. Continue reading
A planet differs from a star. The star is a giant ball composed of hot gases, radiant heat and light. The planet is much smaller in size. It emits no light, but rather, is warmed by starlight.
Let’s look at all the planets in order, starting with the one that is closest to the Sun. The nearest planet to Sun — mercury. The diameter of mercury is 4878 kilometers counts, i.e. equal to the Atlantic ocean. And that means mercury is much smaller than Earth.
The next planet is Venus. It’s almost the same size as our Earth. In diameter it has about 12 100 kilometers, and the Earth’s diameter is 12 kilometers 742,5. By the way, Venus rotates around the Sun in the opposite direction, from East to West. For Venus is Earth, then Mars.
Reddish color of the planet Mars has always distinguished it from other heavenly bodies of the Solar system. The diameter of this planet has 6780 miles. This is slightly greater than half the diameter of the Earth. Mars has always attracted the attention of scientists. Because the surface of this planet is visible to any shape, resembling canals. Out of all the planets of the Solar system except our Earth, on Mars it is most likely sushestvovaniya any form of life, maybe vegetable. Continue reading
Our universe is huge, and it seems to us that more of the globe there can be nothing, but it is not. There are planets much larger and more massive. For the whole of the Universe our Earth is just a grain of sand lost in her. The solar system is only one element of the Galaxy. The sun is the main component of the Galaxy. Eight planets revolve around the Sun. And only ninth – Pluto – due to its gravitational forces and the mass deduced from the list of rotating planets. Each planet has its own parameters, density, temperature. There are those that are composed of gas, there are giant, small, hot, cold, dwarf.
So what is the biggest planet known at the moment? In the spring of 2006 an event occurred that shook the theory about the heavenly bodies. In Rovellasca Observatory (USA, Arizona) in the constellation of Hercules was discovered a huge planet beyond our Earth twenty times. Existing outdoor today it is the largest planet in the Universe. She’s hot and like the Sun, but it’s still a planet. It was called TrES–4. Continue reading
