Your Age on Planet Mars

Mars is the fourth planet from the Sun in the Solar System. The aura of its floor is bloody, due to which it is also known as the "Red Planet". There are two types of planets in the solar system - "terrestrial planets" which have a virtual plane and "gaseous planets" which are composed mostly of gas. Like Earth, Mars is also a planet with a terrestrial surface. Its atmosphere is sparse. Its surface is reminiscent of the Moon's trough and Earth's volcanoes, valleys, deserts and polar snowy peaks. The highest mountain in the Solar System, Olympus Mons, is located on Mars. Apart from its geographical features, Mars' rotation period and seasonal cycles are similar to those of Earth. The possibility of life on this planet has always been envisaged.

Mars can be seen from Earth as a clear orange-red "star". The planet is closest to Earth in the period of opposition, and farthest from Earth in conjunction with the sun, when the two planets are on opposite sides of the sun. Mars is not visible from Earth during a conjunction because it is visually close to the sun. The average synodic period (the time between two oppositions or conjunctions of Mars) is 780 days. Due to the eccentricity of the orbits of Earth and Mars, that period can be 8.5 days off.

Mars is on average 230 million km (about 1.5 AU) from the sun. The sidereal period is 687 (Earth) days (or 1.8809 Earth years), which is the time it takes Mars to complete one orbit around the sun. A sidereal day (the period it takes the planet to rotate around its own axis) on Mars is slightly longer than the Earth day, lasting 24 hours, 37 minutes, and 22.66 seconds. A synodic day on Mars, the time it takes for the sun to reach the same place in the Martian sky, is 24 hours, 39 minutes, and 35.244 seconds and is called a sol. The time unit sol is used for missions on the mars surface, sol 0 is the landing day.

The angle of the rotational axis of Mars with its orbital plane (the obliquity) is 25.19°, almost equal to that of the Earth. As a result, Mars also has seasons, although they are almost twice as long on Mars. In the solar system, only Mercury has an orbit that deviates more from a circle. The change in eccentricity is large: 1.35 million years ago, the eccentricity was only about 0.002, much smaller than that of the current Earth's orbit. The eccentricity changes with a period of about 96,000 Earth years (for comparison, the eccentricity of the Earth's orbit changes with a period of about 100,000 years). However, Mars has an even longer and more important period of change in eccentricity, namely 2.2 million Earth years. Over the past 35,000 years, Mars' orbit has slowly become more eccentric due to the gravitational forces of other planets. The closest distance that Earth and Mars can approach each other in their orbits will decrease slightly over the next 25,000 years.

Mars is about half the size of Earth in diameter and about one-tenth in mass. The total area of ​​the planet is about the same size as the total land area on Earth. Although Mars has a greater mass and volume than Mercury, it has a lower density than both Mercury and Earth. As a result, the surface gravity on Mercury is slightly greater than on Mars. The reddish color of the Martian surface is caused by iron(III) oxide in the form of the mineral hematite or rust.

Because Mars lacks a magnetic field, neither does it have a magnetosphere, the planet's ionosphere is subject to a bombardment of charged particles from the solar wind. As a result, the Martian atmosphere is constantly losing molecules, leaving it thin and tenuous. The Mars Global Surveyor and Mars Express space probes have detected ionized particles moving from the atmosphere into space.

Because Mars has no oceans, and therefore no sea ​​level, an arbitrary zero level also had to be selected for altitude measurements. This level is defined on Mars as the altitude at which the air pressure is 610.5 Pa. This pressure corresponds to the triple point of water (H2O), and is approximately equal to 0.6% of the air pressure at sea level on Earth.

Liquid water can only exist for a short time in the lowest places on the surface of Mars, elsewhere it evaporates or freezes immediately. However, water can exist on Mars in both solid and gaseous states.

According to current insights, whether life is possible on a planet depends on whether there is liquid water on the planet. For this, the planet's orbit must be within the habitable zone around a star. With the sun, the Earth lies within this zone. Because Mars is half an astronomical unit outside the zone and has a very thin atmosphere, there is hardly any liquid water on its surface. However, traces of liquid water from the past show that the planet is potentially capable of harboring life. However, the water on Mars appears to have been too acidic and salty for terrestrial life.

Do you want to know what would be your age if you were born on Mars? So just select your birthdate in the above form and click on the calculate button and this tool will calculate and tell you how many revolutions Mars has made on the Sun and its axis since your birthday. That is, how old are you on Mars in years, months and days, along with this this calculator will also give the date of your next birthday on Mars.
