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 NASA probe New Horizons close to Pluto and will be able to enter the planet’s atmosphere in July of this year
Span New horizons near Pluto in the artist’s impression of NASA.
The ship, which was launched back in 2006 has come nearer to the outer body at a distance that allows you to make high-quality pictures of its surface.
NASA may have to adjust its trajectory in case of detection of unknown cosmic bodies, reports Russia Today .
Apart from the modern equipment on Board the spacecraft is an urn with the remains of the discoverer of Pluto Clyde Tombaugh (1906-1997), CDs with a message to aliens, U.S. coins, flags and postage stamps. On Board the SPACECRAFT is the CD 434 738 names of people who participated in the campaign NASA “Send your name to Pluto” (Send Your Name to Pluto).
Task apparatus is the study of the atmosphere and the ground layers of Pluto, moreover, New Horizons will create a map of the surface of the farthest planet in our System. Continue reading
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
