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 crimson planet come February 18.
Mars is likely one of the best planets to see within the evening sky, blazing bright orange and visual for nearly the entire 12 months. It has been excessive up within the sky because the second half of final 12 months, and you do not 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 a detailed strategy of the moon and Mars—which means they are going to seem subsequent to one another within the night sky.
It isn’t day-after-day you get to see a detailed strategy 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 strategy” is when two objects look closest to one another, even when they don’t seem to be bodily shut. It does not have bodily penalties, however it does look spectacular, and it is an excellent probability 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 will probably be Mars.

It will be a deal with simply getting out and seeing the shut strategy with the naked eye, however when you have binoculars you will additionally have the ability to rise up nearer and extra private with the red planet, and particularly with the moon.
Though Mars is just too small and much away for binoculars to do rather more than make the planet appear like a barely greater orange crimson dot, even a small pair of binoculars can select the Moon’s craters in sharp, hanging element. Sadly, you will not have the ability to catch Mars and the Moon collectively by means of a telescope—they’re nonetheless a bit too far-off from one another for that.
It is price wrapping up heat towards the chilly February air whereas Mars and the Moon transfer additional south and west over the course of the evening. Round 18:40 you can 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 bunch of scorching blue stars greater than 400 gentle years away.
There are excess of seven of them—you can see anyplace between six and 9 with the bare eye, or by means of binoculars or a telescope, and at the moment we all know there are over 1,000. You may monitor 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 bought to be referred to as planets as a result of the traditional Greeks referred to as them planetai or “wanderers”. Proper now, Mars is transferring steadily to the west and you’ll often recognise it by its distinctive color, in addition to its distinct lack of twinkling—stars twinkle, whereas planets do not. So long as it is a clear evening, you’ll be able to typically spot it.
Mars had its closest strategy to Earth again in October final 12 months, which suggests proper now it is getting additional away from us. Because it strikes west, it will even be transferring 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 troublesome—if not unattainable—to identify. From there it units too early for us to see in our skies—however don’t be concerned, it will be again and at a close approach to Earth by 2022.
