Solar system is the planetary system that includes the Sun. and all the objects orbiting it – planets, moons, asteroids. comet. a large number of meteoroids, gas and cosmic dust .
But how was Solar system formed? The universe formed through the Big Bang. There is the Big Bang theory, which says that long ago the universe was small and hot lump. Suddenly it exploded, expanded space, the temperature of the particles decreased considerably. Due to the force of gravity began to gather clouds of matter, the result of which was formed all the galaxies and stars. It took about 8 billion years after the Big Bang, before the Solar system was formed. The matter is unevenly distributed in space and began to attract the dust and gas. Formed dust and gas clouds, they eventually formed star, the Sun. From other particles of the cloud formed other objects.
Components of the Solar system are divided into categories:
3. Small body
The center of the Solar system is the Sun . It accounts for almost all of the bulk system – 99,87 %. Continue reading
The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.
The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.
However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
The planets and moons in orbit of the Sun
The largest planet in the Solar system. this is a Jupiter belonging to the class of gas giants. Ancient astronomers were able to detect and assign a very unusual name this planet. Named in honor of one of the most revered Roman gods, Jupiter is not in vain was honored to be the namesake of the thunder gods. For large-scale weather events, continuously produced in the atmosphere of the giant, strength and scale can outdo the deeds of the most powerful gods! Imagine the worst stormy weather on our planet. And now imagine the same thing, but only 10 times more intense and more powerful. These horrific lightning strikes, as if the gods went crazy and wants to destroy everything. Wild, wild the storm that engulfs everything in its path, and sometimes of centuries.
Jupiter is not alone in its orbit, having 67 different dimensions of the satellites. Like any ordinary giant planet has attracted much attention of scientists. A lot of research spacecraft was sent to Jupiter during the long years of study. Periodically, during the great opposition, Jupiter looks like the brightest star in the heavens. In this period of time activates the monitoring planeteurodisco ground-based and orbiting telescopes. Continue reading
