Interesting Facts about Mars

Updated on February 18, 2010

Mars Facts

A day on Mars is just about 39 minutes longer than that of Earth. This means that it spends about 39 minutes more than Earth to revolve around itself. While a Martian year consists of 686.98 Earth days.

Normally the temperature on this planet remains between -140° C to 20° C

Do you have any idea about age of the red planet. Can you guess? In case you can't, it was formed about 4.5 billion years ago.

Mass of our Earth is ten times the mass of Mars.

It has two small moons named Phobos and Deimos. But no one really knows for sure how they were formed and it is thought that these may be asteroids which were snared by the planet's gravity. These satellites are so small that Phobos has a radius of 11 km while Deimos has a radius of only 6 km.

It is 6794.4 km in diameter.

The atmosphere of this planet is mostly made up of Carbon Dioxide, which according to an estimate is 95.32% of the total atmospheric composition. Nitrogen is the second largest content which makes the 2.7% of the atmosphere.

It is thought that the core of this planet is composed of iron, nickel, and sulfur.


Some More Mars Facts

It has seasons like Earth. This scenario is caused by the tilt of the planet's axis, at a similar angle to the tilt of Earth's axis.

A person who weighs 70 pounds on Earth would weigh 27 pounds on Mars.

The red planet was named after the Roman god of war.

It has polar caps like Earth, containing frozen different layers of carbon dioxide, small amount of water and dust.

The average temperature on the planet Mars is -55 C or -67 F.

Did you know that the third month March is named after Mars, which is not the planet Mars but the god.

Did you know that Mars has the largest canyon in the solar system? It would reach from Los Angeles to Chicago if it was on Earth!

Olympus Mons, the largest mountain in the Solar System, is 550 km wide volcano on the surface Mars which according to an estimate is about 27 km high while our Mount Everest is 8.85 km high.

The mean density of the red planet is 3933kg/m3, while that of the Earth is 5515kg/m3. So, it's density is about 30% less than that of the Earth.

It has almost no atmosphere. The air pressure at the surface of Mars is only 1% of what we have here on Earth.

Mars can be seen from the Earth with a naked eye.

The average distance of Mars from the Sun is almost 228 million kilometers.

Scientists believe that 3.5 billion years ago, Mars experienced the largest known floods in the solar system. Now the question is, where has all this water gone? It couldn't have spilled on Earth from Mars.

The reddish surface of this planet is due to rust. Ferric oxide, which is known as rust, is present on its surface.

      A fascinating hub, UH. Perhaps the 10% of our planet that is above 10,000 feet has many martian qualities including temperature, thinner atmosphere and lower boiling temperature.

      Thank you for these wonderful comments Dohn and Ann.

      Dohn, this life factor makes Mars even more interesting planet. I hope that astronomers will some how reach a unanimous conclusion soon about the existence of life on the red planet.

      Oh, our dear ole Earth. Certainly no planet is more preferable for us than Earth Ann Nonymous.

      This is certainly fascinating, UH. There's certainly speculation that there once was life on Mars, much the same way that there is life on Earth today. Loved the facts, my friend. Thank you!
