The red planet will be able to be seen by the naked eye throughout July, outshining all but the brightest stars. "Only Venus is a brighter star-like object (and it will be visible in the western sky at the same time)".
"But Earth is closer to the sun, and therefore races along its orbit more quickly". Mars on the other hand, being further away, takes 687 days.
Mars won't be this close again till September 15, 2035.
That's because the red planet will be at its closest point to Earth since 2003 throughout June and July, as our planet passes between Mars and the sun.
But some perihelic oppositions bring Earth and Mars closer together than others, the U.S. space agency said. "From our perspective on our spinning world, Mars rises in the east just as the sun sets in the west".
'Then, after staying up in the sky the entire night, Mars sets in the west just as the sun rises in the east.
"Since Mars and the Sun appear on opposite sides of the sky, we say that Mars is in "opposition"," NASA explained.
"An opposition can occur anywhere along Mars" orbit.
Yet the orbits of both planets are slightly tilted, and follow different paths.
Mars will make its closest swing toward Earth, bringing it closer and appearing brighter, than it has in the past 15 years.
The reason for this is a phenomenon called perihelic opposition.
Additionally, other factors contribute to the changes as well. Giant Jupiter especially influences the orbit of Mars.
Mars' orbit is more elliptical than Earth's, and so the difference between its perihelion and aphelion is greater. A dust storm is now walloping Mars, covering around 10 billion acres of the red planet's surface.
So where are the best places to see Mars next month?
"Mars will easily be visible to the naked eye".
The last "perihelic opposition" took place back in 2003, which is considered to be the closest approach in almost 60,000 years, according to NASA.
