One of the biggest mysteries in the world is space. Exactly therefore the space theme, and especially interesting facts related to him, always interesting to users. Next you will find out that the sun losing weight, Saturn – will not drown, and Ursa Major – not a constellation. There are already 8 planets. Older visitors to our site from school curriculum of astronomy and from scientific programs remember that in Our solar system had 9 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. But few people to this day knows that in 2006 the International Astronomical Union decided to remove Pluto from the list of planets of the solar system, due to the fact that she is very small, ranking her among the dwarf to the planets. From this it follows that for now in the solar system – 8 planets. The sun is losing mass Every second our sun loses 4 million tons per second, with a total mass of 1.98892×1030 kg. There is mass loss due to solar winds, they lead to that solar substances overcome gravity and because of this go away into outer space. It’s not worth worrying, these losses are for our era. insignificant, since the loss is 1% of the total mass of 160 billion years. The moon goes farther Scientists have found that the moon moving away from us. Every year, on average, the Moon is 4 farther from us see. This happens due to a slowdown of its rotation by 2 milliseconds in day. There is no reason for concern either, given the distance from the Earth to the Moon is 384 thousand km, then in a year the Moon moves away only 14 meters which, you see, is really insignificant. The rotation of Venus. Everyone knows that the planets around the Sun and around its axis – rotate counterclockwise. However interesting is the fact that Venus is the only planet that rotates around its axis counterclockwise. Saturn would not drowned If you omit many points, then with full confidence it can be stated that Saturn would not have drowned in water, but floated on it surface. The thing is that the density of the planet is 2 times less water density, but to verify this in practice, alas, will not be presented possible. Stars and planets are draws Quite often in the Internet and even in some “tricky” offices can be found offers in which they offer to buy a piece of land on the moon, Mars, and the most enterprising went further – they offer a place in the sun! However, this is all nothing more than a joke, and in some cases – deception, since other planets and stars cannot be someone’s property. Ursa Major – not a constellation On in fact, Ursa Major is not quite a constellation. Scientifically given The phenomenon is Asterism. The fact is that the stars that line up this “constellation”, very distant from each other, being even in different galaxies. Due to the location of the Earth – from here we see all these stars together, and visually it seems that they are the same and are nearby. In general, Ursa Major is part of the constellation Ursa Major. We are all in constant Each of us is constantly in motion, on speeds of 530 km / s, even when sitting. And all this is due to that inside our galaxy we are moving at a speed of 225 km / s, but, but Galaxy itself – at a speed of 305 km / s. Having added all these indicators, we get our constant speed. Of course, the fact of “constant movement “we exaggerated, however, from a scientific point of view, we really in constant motion. For the sake of interest say that while you read our article, you moved to 2 thousand. km
