Our Solar System's Planets: Mars

By -
Here is another astronomy video from Alex McColgan, the owner of the YouTube channel Astrum. 

 The episode explores the fourth planet from the sun, Mars. 

The average distance of Mars from the sun is 142 million miles (228 million km). It is the second smallest terrestrial planet, with a diameter of 4,212 miles (6,780 km). Mars' year is 687 Earth days, and a day on Mars is 24 hours 37 minutes. The average temperature on Mars is -80 F (-60 C) Temperatures on Mars can vary from 95 F (35 C) to -195F (-125 C). The Martian atmosphere is very thin and is 95% carbon dioxide, with a pressure equivalent to .08 pounds psi, or 610 kilopascals.

 I will be seeing if other videos are available on his YouTube channel in the coming days.

Several years ago, I watched a documentary film called The Bridge (2006) , which was about the people that jumped from the Golden Gate Bridge over the course of a year; 23 of the 24 (known) suicides from the bridge that year (2004) were recorded. Snuff films and/or anything related to them are far from my bag to say the least, but I felt compelled to watch this documentary, as my only brother killed himself by jumping from a bridge elsewhere
