Mars and Earth got unusually cosy drawing closer to each other than they have in more than a decade.
The two planets passed at 120.7 million kilometres (75 million miles) away from each other yesterday night, which NASA said will not happen again until July 31, 2018.

The average distance between Earth and Mars is 225 million kilometers (140 million miles), with the neighbouring planets sometimes reaching distances as far as 402.3 million kilometres (250 million miles) when they are diametrically opposite the Sun.
The last time Mars and Earth came this close was in 2005.
In 2003, the celestial bodies were within 56.3 million kilometres (35 million miles) -- the nearest they had been in 60,000 years.
Stargazers will have to wait until 2287 to see Mars at that distance again, according to NASA.
Mars has shone particularly bright since mid-May, as it approached and aligned with the Earth and the Sun.
The Red Planet will stay big and bright through mid-June, after which its intensity will diminish.
