A spectacular sight is promised in our skies this week as Mars will be at it's 'biggest and brightest' for the first time in 17 years - and we won't see it like that again for another 15 years.
The Red planet will be easily visible from earth as it passes directly between us and the Sun on Tuesday, October 13 in a phenomenon known as an 'opposition'.
Mars opposition 2020 will mark the closest the major planet will come to Earth until 2035.
While the official moment of opposition will happen at around 11:20pm when all three planets line up, if you keep your eyes peeled you should be able to see Mars sooner.
After sunset, what looks like a very bright star will rise into the sky on the Eastern horizon. However this 'star' will in fact be Mars, at around 40 million miles away from earth.

While the opposition happens every 26 months, Tuesday night will see Mars almost as big and as bright as it’s been since August 2003, with astrologers claiming we won't get as good a view again for another 15 years.
The Mars opposition in 2003 was Mars's closest approach in 60,000 years.
This year is expected to bring a separation of around 62,069,570km, or 38,568,243 miles making it the narrowest gap now until 2035.
NASA's Lance D. Davis said: "When it comes to observing Mars around opposition, telescopes will show more of the planet’s details, such as dark and light regions on Mars’ surface, and the prominent south polar ice cap, which will be tilted towards the Earth.
"Due to the turbulence of our atmosphere, these details can be hard to see, especially in smaller telescopes."
He added: "The most striking thing about Mars's appearance - whether seen with the naked eye or through a telescope - is its red colour.
"This colour is caused by iron in the rocks on Mars's surface - the same thing that causes the red colour in sandstone formations in the southwestern US."
