Which planet is closer to the Sun?

Mercury, perhaps, is the most mysterious anda little-studied planet in the entire solar system. The ancients called Mercury a god, and fast-footed. Because it rotates around the sun very quickly. The year on this planet is only 87.96 days. So which planet is closer to the Sun? It is Mercury. That's why his year is so short, because he has to overcome the smallest distance. But this is not all the "records" of this planet. When Pluto was stripped of planet status, Mercury became also the smallest planet in our solar system. (Its radius is 2438.9 km). Mercury always asked scientists mysteries, some of which, no answer to this day. For a long time it was believed that the day on this planet is equal in duration to the year. That is, he always turns to Svetl only one side, and the other is in darkness. This caused a lot of controversy among scientists, and gave the imagination of the science fiction writers food for thought. But, in the end it turned out that the day on Mercury is shorter than the year (about 59 terrestrial). There is on this planet, and another miracle. It is associated with the difference in velocities of the planet's orbit and its rotation around the Sun. At times, the difference in speed creates a phenomenon that is described in the Bible. When the Sun starts moving in the opposite direction. However, a person is unlikely to be comfortable watching this phenomenon. The temperature on the planet ranges from + 428 to -183. Unpleasant weather, is not it?
