If you are lucky not to be in a city like Curitiba, which insists on clouding at every astronomical event, you can, tonight (21), observe the alignment of Mars and Uranus. To watch the show, just look for the Moon, since both planets will be close to it.
While Uranus, the seventh planet in the Solar System, orbiting the star at a distance of 2.9 billion kilometers, will have an apparent magnitude of 5.8, Mars, just 231.1 million kilometers from the Astro Rei, will be much brighter, with 0.2 of magnitude. In this case, less is more, since, for example, the Sun has -27.
Unfortunately, the distance between the two celestial bodies will be too great for the scene to fit into a telescope’s field of view, according to in-the-sky.org. Anyway, binoculars will be of great help to observers, since identifying all the elements, including the less sumptuous ones, is much easier with accessories of this type.
One more help
Need more detailed tips to know who’s who in this story? O Jet Propulsion Laboratory, from NASA, provided them. When you encounter the Moon, take a loving look until you find where the Red Planet is. Then, in line with it, there will be a kind of bluish disk – which, in this case, is Uranus. In fact, it’s not just the two of them who will participate in the parades to Earth. There are those who stay in the background.
Jupiter and Saturn will officially continue across the sky, albeit hidden (if, of course, everyone else isn’t too). Taking a photo of the protagonists, be sure to share.
After all, many people will have to make do with what appears on someone else’s timeline, without actually seeing anything beyond what their own eyes can see.
