The red planet is the second name for Mars, which is close enough to Earth. It is quite possible to observe the “neighbor” in the starry sky without a telescope.
Mars, belonging to the Earth group, is the fourth planet from the Sun. For comparison: the Earth occupies the third position in our solar system.
The Red Planet is our “Neighbor”
The name "red" is primarily associated with its shade.
How long is the day on Mars?
The orbital period of Mars around the Sun is 687 Earth days. That is, the year on Mars lasts almost twice as long as on Earth.
This is due to the fact that the distance to it is 1.62 times longer than from us to the Sun, and the orbital period, naturally, takes longer.
How long is the day on Mars?The length of the day on Mars is quite close to the Earth indicators. Only in this planet of our solar system, this period is as close as possible to us in comparison with the others.
Regarding the duration, the day on Mars in hours, familiar to our understanding, will be 24 hours and 37 minutes.
This indicator slightly exceeds Earth days. The reason of how long a day on Mars lasts is, first of all, the speed of the circulation of the Red Planet around its axis.
The length of the day on the planets of our solar system
What is the duration of the day, depends on the distance to the Sun and the speed of rotation around its own axis of each planet. There are days star and solar.
The magnitude of the difference between them depends on a combination of two factors - these are periods of revolution around the Sun and circulation around its axis.
Consider the duration of the day and year on other planets and compare with how long the day lasts on Mars and Earth.
The first and closest planet to the Sun is Mercury. Starry days on this planet are 59 Earth days, and the sun lasts about 176.
As for Venus, due to its turning in the opposite direction, the sidereal days have a duration of 223 Earth days, and the solar days make 117 days.
The Earth, on the other hand, has 24 hours in the sun, a stellar day is slightly shorter and is 23 hours and 56 minutes.
The length of the day on Mars is stellar and solar like duration on Earth. And they are respectively 24 hours 37 minutes and 24 hours and 40 minutes. That is, a day on Mars lasts 24 hours and 40 minutes.
As for the giant planets, then on Jupiter itis almost ten o'clock, on Saturn - about 10 hours and 34 minutes. On Neptune, about 16 hours, and on Uranus - 17 hours and 15 minutes. The difference between the solar and sidereal days on these planets is insignificant. This is due to the long period of revolution around the sun.
As we can see, of all the planets in terms of duration, in comparison with the Earth, Mars is the most similar.
A day on Mars, as well as on our planet, is four minutes longer than the sidereal day.
On the other planets, the difference is more significant, so much similarity is not observed.
The day on Mars is the same as on Earth
In 2023, an expedition to Mars is planned. This time, unlike conventional probes exploring the planet, people will fly aboard a spacecraft.
This rather complex mission is associated with the fact that the conditions for people to live are much more difficult than on their home planet, and going out into open space is impossible without means of protection.
One of the questions on the adaptation of the new Martian inhabitants is the reaction of the organism to how long a day on Mars lasts, unlike Earth conditions.
Will this be a full biological adaptation? According to physiologists, such a small difference in 37 minutes will be perceived quite easily by the settlers.
Many difficulties are expected, but perhapsdespite this, a day on Mars, so similar to ours, will remind astronauts of their own home. No wonder the Red Planet is called the twin of the Earth. Its similarity is great, but habitability is minimal.
Similar but not welcoming
Against the background of a high level of radiation to protect the settlers, it is planned to build residential complexes specifically designed to protect against harsh conditions.
On Mars, there is practically no atmosphere, increased discharging. In the air of the planet is mainly carbon dioxide.
As for the climate, it is quite severe. At the equator, in summer, the temperature rises to the maximum of +27 degrees Celsius.
Due to this, the change of seasons is similar to the usual local conditions. But still, the year on Mars is almost twice as long as Earth's earth and is almost 687 days.
Based on how long a day lasts on Mars, and from the total number of days in the Martian year, we get that the first settlers will see the Sun 670 times during the Martian year.
Future astronauts
В связи с этим у организаторов и учёных миссии there is another problem that is technically almost solved. It is associated with the synchronization of our and Martian time. The scientific term "Sol" is called the day on Mars or the duration of the day.
Именно таким образом новые жители Марса станут call your day and say that two or three solas have passed. Well, let's hope that such a grand mission will be successful and open a new interplanetary epoch of the future.
