Did you know that in many ways, the planet Mars is much like the planet Earth? The small "red" planet has seen volcanic eruptions, meteor showers, shifting tectonic plates and even dust storms. The planet even has growing and receding polar ice caps, that show changes in seasonal temperature. Mars is a terrestrial planet, along with Earth, Venus and Mercury.

Mars is too cold and has too thin an atmosphere to allow liquid water to exist at the surface, but evidence clearly shows that about 3.5 billion years ago, Mars was thought to bear a lot of water, even existing in small streams and lakes.

This planet is one of the planets closest related to earth, in terms of sustaining human life. The force of gravity on this planet is 62% less than that of Earth, however, therefore if you weighed 100 kilograms on earth, you would weigh 38 on Mars.

I find our solar system to be a very complex and interesting group of planets. There are 8 planets in our own solar system, but that does not mean there are only 8 out there. There are hundreds of billions of galaxies out there, consisting of their own planets that could potentially sustain human life as well. Think of all the possibilities out there!
