As long as the sky is clear, you can observe the planet with the naked eye, it will be the brightest element of the sky, after the moon.
At near the lunar eclipse, the sky regales us again. Tuesday night, the red planet will be closer to the Earth for 15 years. A phenomenon that has already occurred in 2003, but that will not happen before … 2287!
In scientific terms, we speak of an "opposition of Mars", that is to say that Mars is opposite to the Sun in relation to the Earth. This implies that when the Sun sets, in the west, Mars rises, to the east, and is therefore visible all night long. In fact, this phenomenon occurs every two years or so. But as the orbit of Mars is oval, Mars and the Earth are not always at the same distance.
What is exceptional this year is that the Earth-Mars distance will be only 57.6 million km. A straw, in short!
In 2003, it was approaching 55 million km.
If the sky is clear, you can observe the planet with the naked eye, it will be the element the brightest of the sky, after the moon. Otherwise, NASA broadcasts the event live.
