Every student knows about the existence of the planet Venus in the solar system. The fact that it is the closest to the Earth and the second from the Sun, not everyone will remember. Well, to name more or less accurately the period of revolution of Venus around the Sun will be able to unit. Let’s try to fill this knowledge gap.
Venus - the planet of paradoxes
Start with a brief description of the planet. Closer to the Sun in our system is only Mercury. But Venus is closest to the Earth - at some points the distance between them is only 42 million kilometers. By space standards, this is quite a bit.
And the size of the neighboring planets is quite similar - the length of the equator of Venus is 95% of the same indicator on Earth.
But for the rest, solid differences begin. To begin with, Venus is the only planet in the solar system that has reverse or retrograde rotation around its axis. That is, the sun here does not rise in the east and sets in the west, as on all other planets, but vice versa. Very unusual and unusual!
Year duration
Now let's talk about the period of revolution of Venus around the Sun - it is equal to almost 225 days or, more precisely, 224.7. Yes, it takes so much time for the planet to make a complete revolution around the luminary - 140 days more than it takes for the Earth. No wonder - the farther the planet is from the Sun, the longer the year there.
But the speed of movement of the planet in space is quite high - 35 kilometers per second! In one hour it passes 126 thousand kilometers. Just imagine the distance it travels over a year, given the stellar period of Venus's revolution around the Sun!
When the day is longer than a year
Saying for what period Venus makes a complete revolution around the nearest star, it is worth noting its period of revolution around its own axis, that is, a day.
This period is really impressive. The planet spends as much as 243 days to make only one revolution around its axis. Just imagine this day - longer than a year!
It is precisely because of this that the inhabitants of Venus, if they existed there (the existence of at least some kind of life is highly doubtful due to features that we will discuss a bit later), would fall into an unusual position.
The fact is that on Earth, a change in the time of day is due to the rotation of the planet around the axis. Still, the day here lasts 24 hours, and the year is more than 365 days. On Venus, the opposite is true. Here, the time of the day depends more on where exactly the planet is located in its orbit. Yes, this is what affects which parts of the planet will be lit by a hot body, and which will remain in the shade. Because of this state of affairs, it would be very difficult to live by the clock here - sometimes it would be midnight in the morning or evening, and even at noon the sun would not always be at its zenith.
Unfriendly planet
Now you know what is the period of revolution of the planet Venus around the Sun. You can tell more about her.
For many years, science fiction writers, relying on the assertion of scientists that Venus is almost equal in size to the Earth, inhabited it in their works by a variety of creatures. Alas, in the middle of the twentieth century all these fantasies collapsed. Recent data have proved that at least something can hardly survive here.
Start at least with the winds. Even the most monstrous hurricanes of the Earth will seem in comparison with them a light pleasant breeze. The speed of the hurricane is about 33 meters per second. And on Venus, almost without stopping, the wind blows up to 100 meters per second! No earthly object could resist such a pressure.
Everything is not too rosy with the atmosphere. It is completely unsuitable for breathing, since it consists of 97% carbon dioxide. Oxygen is either absent or is available in the smallest amount. In addition, the pressure here is just monstrous. On the surface of the planet, the density of the atmosphere is approximately 67 kg per cubic meter. Because of this, stepping on Venus, a person would immediately feel (if he had time) the same pressure as in the sea at a depth of almost a kilometer!
And the temperature here is absolutely not conducive to a pleasant pastime. During the day, the surface of the planet and air warms up to about 467 degrees Celsius. This is much more than the temperature of Mercury, the distance from which to the Sun is two times less than from Venus! This is easily explained by the extremely dense atmosphere and the greenhouse effect created by the high concentration of carbon dioxide. On Mercury, heat from a hot surface simply evaporates into outer space. Here, the dense atmosphere simply does not allow him to leave, which leads to such extreme indicators. Even at night, which lasts four Earth months, it only gets 1-2 degrees cooler here. And all due to the fact that greenhouse gases do not allow heat to leave.
Conclusion
This can end the article. Now you know the period of revolution of Venus around the Sun, as well as other features of this amazing planet. Surely this will significantly expand your horizons in the field of astronomy.
