MARS

Mars is also called The Red Planet and is the fourth planet in the order away from the sun.Its the second planet smallest after Mercury.

               
                                              It has two satellites, and the seasonal cycles are similares to the Earth , Mars is home to Mount Olympus , the largest volcano and the second highest known mountain in the solar system.

There are ongoing investigations assessing the past habitability potential of Mars , as well as the possibility of extant life .

                    PHYSICAL CHARACTERISTICS

Volume : 1.6318 times 1011 Km3
. Mass : 6.4171 times 1023 Kg .

Diameter : 6794,4 Km .

Gravity : 3,711 m/s2 .

                        ATMOSPHERE
Surface pressure : 0.636 kPa

There in the planet , Mars , its very cold , the minimum has been of - 87 degrees and the maximum has been of 20 degrees.
If it is average of temperature it is usually is of -46degrees.
The average distance between Mars and the Sun is approximately 230 million kilometers .

The solar day of Mars is only slightly larger than that of Earth , 24 hours , 39 minutes and 34 seconds.A year on Mars equals 1.8809 Earth years , or 1 year , 320 days and 18.2 hours.
Mars has two satellites , one of them is Deimos .And the other of them is Fobos .

                   IS THERE LIFE IN MARS?

Current theories that predict the conditions in wich life can be found require the availability of liquid water , so their search is so important . A study published by NASA said that 4300 million years ago and for 1500 millions years , the planet have an extensive ocean in the north of the hemisphere , with a volume greater than that of the Artic , sufficient to cover all Martian territory with 130 meters depth .
