Although there are 7 planets that are in the Solar System in addition to ours, the Earth, it is not easy to be able to observe them all at the same time from the same point at the same time of the year, much less at a certain time. Although, there are certain situations in which we can observe several at the same time, due to the position they occupy in their orbits and the sector of the Solar System visible from our position, explains Víctor González at

In simple words, a planetary conjunction occurs when two or more planets appear close to each other in the sky. This proximity of planets is an optical illusion: in reality, they are very far from each other.

In this case, we will be able to see up to 5 planets in the night sky: Mercury, Venus, Mars, Jupiter and Uranus. The remarkable thing will not be so much their proximity, but the number of them that will be visible, since They will be located in a sector of the sky less than 50 degrees apart. Therefore, strictly speaking, it will not be a “conjunction” like the one we observed between Venus and Jupiter at the beginning of the month.

Its maximum visual approach will be this Tuesday, March 28th, but it will be possible to observe them in the following days on this date.

The closest planets to the Sun Mercury and Venus will only be visible in the early evening. Mercury can be difficult to observe if we don’t have a clear horizon, but Venus is so bright that it will attract attention Enough, especially after dark.

If we have powerful binoculars or a small telescope we can verify that these inner planets have phases (like the Moon) appreciating an area lit by the Sun and another dark. Mars, on the other hand, will remain visible high in the sky, less bright than Venus, but with an unmistakable reddish glow.

Jupiter during these next few days will remain close to the horizon in the early evening, not far from Mercury, but brighter than it. Although its proximity to the horizon can make it difficult to see certain details, With a small telescope we can clearly observe its 4 Galilean satellites: Io, Europa, Ganymede and Callisto.

Uranus, on the other hand, with its characteristic bluish glow, will remain hidden in plain sight. This planet is very far away and requires powerful binoculars or a small telescope to observe well as a sky with less light pollution than what we can find in the center of a city.
