Interesting facts about the cosmos: amazing scientific facts
Planets already 8
More adult visitors of our site from the school program of astronomy and from scientific programs remember that in our solar system there were 9 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. But few people to this day know that in 2006 the International Astronomical Union decided to withdraw Pluto from the list of planets of the solar system, because it is very small, categorizing it as dwarf planets. From this it follows that for the present in the solar system there are 8 planets.
The sun loses mass
Every second our Sun loses 4 million tons per second, with a total mass of 1.98892 × 1030 kg. There is a loss of mass due to solar winds, they lead to the fact that solar substances overcome gravity and because of this go to outer space.
It's not worth worrying, these losses for our era are insignificant, since the loss is 1% of the total mass of 160 billion years.
The moon is farther away
Scientists have established that the Moon is moving away from us. Every year, on average, the Moon from us is further 4 cm. This is due to the slowing of its rotation by 2 milliseconds per day.
There is also no reason for concern, because taking into account the distance from the Earth to the Moon in 384 thousand km, then in the year the moon retreats only 14 meters, which, you will agree, is really insignificant.
Rotation of Venus
Everyone knows that the planets around the Sun and around the axis of their axis rotate counter-clockwise. However, interesting is the fact that Venus is the only planet that rotates around its axis counter-clockwise.
Saturn would not have drowned
If you omit many points, then with full confidence you can say that Saturn would not have drowned in water, but floated on its surface. The thing is that the density of the planet is two times less than the density of water, but to check this in practice, alas, it will not be possible.
Stars and planets - draws
Quite often on the Internet and even in some "cunning" offices, you can find offers that offer to buy a piece of land on the Moon, Mars, and the most enterprising have gone further - they offer a place on the Sun! Nevertheless, this is nothing more than a joke, and in some cases - a deception, since other planets and stars can not be someone's property.
The Big Dipper is not a constellation
In fact, the Big Dipper is not quite a constellation. Scientifically, this phenomenon is Asterism. The fact is that the stars that build this "constellation" are very far from each other, even in different galaxies. Thanks 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 near.
In general, the Big Dipper is part of the constellation The Great Bear.
All of us are in constant motion
Each of us is constantly on the move, at a speed of 530 km / s, even when sitting. And all this is due to the fact that within our Galaxy we are moving at a speed of 225 km / h, but, and the Galaxy itself - at a speed of 305 km / h. Adding all these indicators, we get our constant speed.
Of course, the fact of "constant movement" has been exaggerated, nevertheless, from the scientific point of view, we are really in a constant movement. For the sake of interest, it should be said that as long as you read our article, you have moved to 2 thousand km.
