Final 12 months was the 12 months of Mars launches, and this one would be the 12 months of Mars landings. The Hope Mars mission, launched by the United Arab Emirates, entered its orbit round Mars on February 9, whereas China’s Tianwen-1 rover, now orbiting the planet, will land in Might. In the meantime, Nasa’s Perseverance rover will land on the purple planet come February 18.
Mars is likely one of the best planets to see within the evening sky, blazing shiny orange and visual for nearly the entire 12 months. It’s been excessive up within the sky for the reason that second half of final 12 months, and also you don’t want any particular tools to see it.
This implies there are some nice alternatives to see the planet travelling throughout the evening skies, together with simply because the Perseverance rover is touching down. The day the rover lands, there can be an in depth method of the moon and Mars – which means they may seem subsequent to one another within the evening sky.
It’s not day by day you get to see an in depth method whereas a rover makes its touchdown. Wrap up heat and search for the Moon and Mars collectively as, 200 million km (124 million miles) away, Perseverance lands.
Right here on Earth, we see shut approaches due to what astronomers name the obvious movement of our Moon and the planets within the sky. As a result of the Earth and the opposite planets take completely different occasions to go round our Solar, and since the moon takes time to go round Earth, generally planets and our Moon look shut to one another within the sky.
An “appulse” or “shut method” is when two objects look closest to one another, even when they’re not bodily shut. It doesn’t have bodily penalties, however it does look spectacular, and it’s a terrific likelihood to take some house and do some planet watching.
On February 18, Mars rises simply after sundown, at 17:40 (GMT), and joins a waxing crescent moon. Wherever you’re on the earth, look south for the Moon, and the little orange-red dot you see close to it will likely be Mars.

It’ll be a deal with simply getting out and seeing the shut method with the bare eye, however when you have binoculars you’ll additionally have the ability to rise up nearer and extra private with the purple planet, and particularly with the moon.
Though Mars is simply too small and much away for binoculars to do way more than make the planet seem like a barely greater orange purple dot, even a small pair of binoculars can select the Moon’s craters in sharp, putting element. Sadly, you gained’t have the ability to catch Mars and the Moon collectively via a telescope – they’re nonetheless a bit too distant from one another for that.
It’s price wrapping up heat in opposition to the chilly February air whereas Mars and the Moon transfer additional south and west over the course of the evening. Round 18:40 you’ll have the ability to lookup and to the left of Mars to see a set of fuzzy, twinkling pinpricks. These twinkly pinpricks are the Pleiades or the Seven Sisters, a gaggle of scorching blue stars greater than 400 gentle years away.
There are excess of seven of them – you’ll have the ability to see wherever between six and 9 with the bare eye, or via binoculars or a telescope, and immediately we all know there are over 1,000. You may observe the Moon, Mars and the Pleiades throughout the sky till they set within the west simply after 13:00.
Planets transfer throughout the sky. That is how they obtained to be known as planets as a result of the traditional Greeks known as them planetai or “wanderers”. Proper now, Mars is shifting steadily to the west and you may normally recognise it by its distinctive color, in addition to its distinct lack of twinkling – stars twinkle, whereas planets don’t. So long as it’s a transparent evening, you may typically spot it.
Mars had its closest method to Earth again in October final 12 months, which suggests proper now it’s getting additional away from us. Because it strikes west, it’ll even be shifting previous the Pleiades into the constellation of Taurus, the bull. By April Mars can be seen straight above Aldebaran – the brightest star within the constellation Taurus. By Might, Mars strikes into the constellation of Gemini however is sadly low within the sky.
You may see Mars and Venus collectively in early July, low on the western horizon. However by August, Mars can be tough – if not unimaginable – to identify. From there it units too early for us to see in our skies – however don’t fear, it’ll be again and at an in depth method to Earth by 2022.
