How many planets are in the solar system?

If you are an inquisitive person - then you probably will be interested to know the answer to the question of how many planets in the solar system. On this subject between astronomers for many years are fierce controversy. Not so long ago a man who was interested in planets in the solar system could say without hesitation - their 9. At the moment this is not so, because Pluto was removed from the list. Only seventy-odd years, he managed to keep this proud title. Let's see how many planets in our solar system now.

There are 8 of them at the moment, they revolve, of course, around one of the brightest stars in the galaxy - the Sun.

They are divided into two groups - four so-called internal ones, which are close to the star, and as many external ones - which are sufficiently removed from it, but are large in size and are considered gas giants.

First we will talk about the first.

The smallest planet of the system is Mercury. To the Sun it is closest to all the others, but has no satellites at all. The surface is strewn with a huge number of craters of different diameters. There is no atmosphere.

Next, which will attract people who are interested in how many planets in the solar system are Venus. Slightly inferior to our native Earth in size, satellites are absent absolutely.

Then our planet is the only one, the existence of life on which is for certain known. It is on Earth that the atmosphere is so unique that it allows the very existence of living beings.

The next in the list is, of course, Mars, the red planet on which the next American rover landed recently. Favorite place of science fiction writers, and scientists in general.

Then follows the largest object after the Sun in our system. It is many times larger than any planet in our system. Has a huge number of satellites - as many as sixty-three. The largest of them - Ganymede, it is even more massive than Mercury. Jupiter is also remarkable for its large red spot, according to scientists, a huge storm that has been known for more than three centuries.

Then goes Saturn - the second largest in the system. It is famous for its rings, consisting of different particles. Also has many satellites - 62 pieces.

The next in the list is Uranus, part-time being the coldest of all planets located in the system. Firstly, it is known that it rotates around the sun in a different way than normal planets, but as if on its side. The minimum temperature on this planet is -224 degrees.

After the discovery of Uranus in its day, the scientists thought they firmly know how many planets in the solar system. However, after all distortions in its orbit have been taken into account, it became clear that there are other celestial bodies of similar size.

Therefore, although somewhat later, in 1846, after much research, Neptune was discovered. At the moment, it is the planet most distant from the Sun in our system. It was discovered by a curious method - the scientists determined the location before they saw it in the telescope. This was done using conventional mathematical calculations. It is known that he has a total of thirteen satellites. It is blue - but this is due not to the presence of water, as in the case of our planet, but to large concentrations of methane in the atmosphere.

Let's hope that a fairly detailed answer to the question of how many planets in the solar system we have given. Of course, I would like to include in this list also Pluto - but the one, as mentioned at the beginning of this article, to deep regret, dropped out of the official lists.

Although there is absolutely no point in paying attention to changes in scientific views, all the planets are still in their places, whatever the concepts changed by scientists.
