The red planet will be closer to Earth this Friday 29th, a phenomenon that astronomers call opposition.
This occurs when Mars is aligned with the Sun and the Earth, ie, when our planet is between the two stars. The distance between us and Mars will be about 100 million kilometers.
A good tip for anyone who wants to observe the phenomenon is to look in the direction opposite the sunset. Mars will appear just above the horizon, as were a large red star. The planet can be seen between 20h and 20h30.
The last time this phenomenon occurred was in December 2007, and next time will be in March 2012.
