Mars is set to be its most visible in nearly 20 years!

On Tuesday, 13 October, you'll be able to see Mars at its brightest.

Mars is 212.9 million km away from the sun.

It's predicted it won't be as bright as this again until 2035 - so make sure you take a look!

Mars will be closer to Earth than it has been in the last two years. Earth passes directly between the Sun and Mars once every 26 months. This means Mars will be in 'opposition'.

This opposition will be extra special due to the orbits of Earth and Mars lining up to be at their closest to each other.

According to Nasa when this happens, the minimum distance from Earth to Mars is about 33.9 million miles (54.6 million kilometers). However, that doesn't happen very often.

Nasa has said that the position that Mars will be in, means people from Earth will be seeing an 'effectively full Mars.' This will be the best chance to see our next door neighbour in the solar system in nearly 20 years!

You'll be able to look for Mars, when the Sun is setting. As the Sun sets, Mars will rise, and Mars will set as the Sun rises. You don't have to be a professional star gazer to see it either.

It won't be as bright as the Moon, but you should be able to look up and, if you are looking in the right place - spot it

October is set to be quite the month for spotting things in the sky. There's a full moon and a blue moon on Halloween to look out for too.

Will you be looking out for Mars, do you star gaze? Tell us all about it in the comments below!
