    Facts About Mars

DiD U Know! Planet MARS . Only Mercury is smaller than Mars, which is the second-smallest planet in the Solar System and the fourth planet from the Sun. Mars is a terrestrial planet that has a thin atmosphere (less than 1% the thickness of Earth's), a crust mostly made up of elements found in Earth's crust, a core formed of iron, and a surface comprised of nickel and iron. In this article I will tell you about planet Mars and some interesting facts about it. So let’s start:

Size:

• Mars is much smaller than Earth, which has a diameter of 7,926 miles (12,756 km), at 4,220 miles (6,791 km).
• The Red Planet has a gravitational pull that is 38% stronger than Earth's and is around 10% as big.
• A human weighing 100 pounds on Earth would only weigh 38 pounds on Mars, despite both planets having the same mass.

Composition:

• Iron, nickel, and sulphur most likely make up Mars' solid core. Given that peridotite, which is predominantly composed of silicon, oxygen, iron, and magnesium, makes up the majority of Mars' mantle, it is likely comparable to Earth's mantle in this regard.
• Although certain crustal rocks, particularly in the northern hemisphere, may be a type of andesite, a volcanic rock that contains more silica than basalt does, the majority of the crust is likely comprised of the volcanic rock basalt, which is also frequently found in the crusts of the Earth and the moon.
• It is generally well recognized that Mars may have once had rivers and seas. According to observations, water may have last been present on Earth 2 billion years ago.
• Whether there is still much water there now is unknown. Observations of black streaks that appear to flow downward have been made by several probes, although it is still unclear what exactly these findings signify.
• In 2020, researchers believed they had discovered proof of submerged lakes of liquid water beneath Mars' south polar ice cap, but further data revealed that they were probably clay deposits that created dazzling radar reflections that resembled pools of water.

Atmosphere:

• The layer of gases that surrounds Mars is known as its atmosphere. It is mostly made of of argon (2%), molecular nitrogen (2.8%), and carbon dioxide (95%). Water vapour, oxygen, carbon monoxide, hydrogen, and noble gases are also present in trace amounts. Compared to Earth, Mars has a far thinner atmosphere.
• Less than 1% of the Earth's pressure, or 610 pascals (0.088 psi), is the average surface pressure. Liquid water cannot exist on the surface of Mars at the moment due to the thin atmosphere, although several studies indicate that the atmosphere was formerly much thicker.
• When carbon dioxide partially freezes at the polar caps during the winter, the increased density experienced in the spring and fall is decreased by 25%.
• Mars has a cooler atmosphere than Earth. Mars is further away from the Sun than Earth, which results in less solar radiation reaching it. As a result, Mars' effective temperature is lower, at roughly 210 K (63 °C; 82 °F).
• Only 215 K (58 °C; 73 °F) is the average surface emission temperature of Mars, which is equivalent to interior Antarctica.
• The low concentration of other greenhouse gases may account for the Martian atmosphere's lesser greenhouse effect (5 °C [9.0 °F] compared to 33 °C [59 °F] on Earth).
• Due to its low thermal inertia, the lower atmosphere's temperature has a wide daily variation; in some areas, it may vary from 75 °C (103 °F) to almost 0 °C (32 °F) close to the surface.

Unbelievable Facts:

1) Mars, the fourth planet from the sun in our solar system, is named for the Roman God of War.

2) Mars is sometimes referred to as the "Red Planet" simply because it is red! Iron oxide, often known as rust causing or iron, is a chemical that is abundant in the rocks and soil of this region and is responsible for giving it its distinctive and beautiful colour.

3) After Mercury, Mars is the second-smallest planet in the solar system. It is nearly half the size of Earth, measuring 6,791 kilometers in diameter (distance through the centre).

4) Because Mars is further from the sun than Earth, it can get rather chilly there—much colder than Earth. Temperatures can reach 20°C in the equator, while they can drop to -140°C at the poles.

 5) Olympus Mons, a volcano on Mars, is the tallest peak in the solar system. It is almost three times as tall as Mount Everest, standing a staggering 24 kilometers high!

6) On Mars, you could leap three times higher than you can on Earth. Boing! This is due to the planet's significantly lesser gravity, which holds us on the ground.

7) Do you enjoy watching the moon in the evening? Well, have a look at this — Two moons orbit Mars. Deimos and Phobos are the names of the two.

8) A day on Mars lasts for 24 hours and 37 minutes, which is not much longer than a day on Earth. However, a year on Mars lasts 687 Earth days, which is almost twice as long! This is due to the fact that it takes far longer than Earth for its orbit to be complete.

9) Up until recently, scientists thought that the surface of Mars consisted primarily of rocks, dirt dust, and ice. But… news alert! They discovered evidence of a lake beneath the planet's south polar ice cap in 2018. exciting material

10) While there are currently no humans on Mars, scientists have launched spacecraft there to do study on this amazing planet. The Viking Landers, which landed on Mars' surface in 1976, were the first spacecraft to do so.
