As time goes on, the entire sky increases four minutes earlier each evening or just a half an hour per week.
The five wandering planets specifically — Mercury, Venus, Mars, Jupiter and Saturn have been observed for thousands of years. People who followed the nighttime skies on a regular basis took note they slowly crawled against the background stars. These five planets, along with the Sun and Moon, give us our seven days of this week. Uranus and Neptune could only be viewed with a telescope.
Like runners onto a round track, the interior planets move much faster around the Sun than the outer ones. For example, Mercury orbits our daytime star in just 88 times whereas Saturn takes 29 years to finish a lap. Every 26 months Earth and Mars move close to one another, and therefore are considered especially close every seventh time. Mars will be at its brightest from July 27-30, and this will be its best screening since 2003. In this time our worlds will nevertheless be separated by 57 million kilometres. Keep watching Mars over the weeks and months as our distance increases it becomes darker. The good thing is Mars is experiencing a global dust storm, thus obstructing surface characteristic from telescopes.
People have always had a specific fascination with Mars, especially since its near approach (resistance ) in 1877.
Some 3.5 billion decades ago, Mars was a wet planet just like Earth, but lost its own water and is now a dry and barren world. But life might still exist much under the surface. Within another twelve decades of so, people will put foot on this mysterious world. Mars One will include dangerous and courageous missions, as a one time excursion takes seven weeks. And for the first courageous team of four there will not be a return flight back home. Future assignments will send another group of four every two years. Finally there will be missions back to Earth but not for a long time to come. We thank individuals who forfeit their own lives in the name of science and exploration.
