[Mis à jour le 16 juin 2023 à 23h29] Astronomy lovers, be ready to get up at dawn. This Saturday, June 17, 2023, a celestial spectacle of rare beauty will occur in the sky. No less than five planets will align for almost an hour. To observe this phenomenon, you will therefore have to set your alarm clock and get up even before the sun, unless you prefer to have an all-nighter. It remains to be seen whether the sky will be clear enough where you are. If this is the case, the ideal is therefore to turn your gaze to the horizon, towards the east, around 4:45 a.m., an hour before the sun emerges and the sky becomes too bright to observe. such a sight.

This type of phenomenon generally remains visible for a few days provided you benefit from mild weather and choose a place where the horizon is clear. It will therefore be possible to enjoy it during the weekend and the beginning of next week.

To admire the grand alignment of planets, go about an hour before sunrise. Sun, around 5:30 a.m. Prefer a place where you will have a clear view because Mercury will be very low on the celestial vault. Scan the sky towards the east just above the horizon and you will see the various stars. Jupiter, Saturn and Mercury will be visible to the naked eye provided the weather is good and the sky clear of clouds. On the other hand, Uranus and Neptune, which are further away from us, can only be observed using a telescope or astronomical binoculars.

Looking at the horizon, you should encounter the planet first Mercury then going up, you will be able to see Uranus, Jupiter, Neptune then Saturn. All these planets will be located along an imaginary line. To locate the different stars, you can use an application like Sky Tonight (on App Store And Google Play) or StarWalk (on App Store And Google Play). The spectacle will be visible for about an hour, then the Sun will appear and its luminosity will gradually mask the planets, starting with Mercury.

What is the alignment of the planets?

A planetary alignment is an astronomical phenomenon that occurs when multiple planets come together on one side of the Sun. This is an optical illusion since the planets are not actually aligned in three dimensions of space. On the other hand, as they all revolve around the Sun in the same plane called the ecliptic, these planets align in the terrestrial sky.

When the stars are aligned?

Observed from Earth, the planets line up in the sky when they are on the same side of the Sun so that they are visible in the Earth’s sky. We commonly observe up to three or even four planets aligned but it happens from time to time that they are more numerous to join the spectacle. We then speak of a grand planetary alignment or of a complete grand planetary alignment if all the planets of the solar system are at the rendezvous.

When will all the planets be in perfect alignment?

It is extremely rare for all the planets in the solar system to line up in the sky. Indeed, for this it is necessary that all these stars are found on the same side of the Sun and are placed in such a way that they are visible from the Earth. This is called a complete grand planetary alignment. The last alignment of this type took place in June 2022 and the next one is scheduled for 2124. We will have to be patient!

What is a parade of planets?

While planetary alignment is an astronomical concept that refers to the fact that several planets group together on one side of the Sun, the term parade is a more familiar term to speak of the simultaneous presence of several planets in the Earth’s sky. Parry is therefore the consequence of planetary alignment. This is the spectacle observed from Earth.

​​​​​When will the next alignment of the planets be?

Here are the dates of the next planetary alignments that you can admire from Earth in 2023:

  • On July 22, there will be a mini alignment of Mercury, Venus and March
  • On August 24, two successive alignments will take place during the night. This is the mini alignment of Mercury, Mars and Saturn at the beginning of the night then the small alignment of Uranus, Jupiter, Neptune and Saturn.
