The Moon and all the planets of the Solar System are about to line up in the sky. This is what you need to know – Teach me about Science

Throughout this month 5 planets have adorned the morning sky, now the Moon also joins the show: the June 23 The Moon and 5 planets will line up in the sky and you can see them without a telescope. Also in the show will be Neptune and Uranus (not visible to the naked eye), so it will actually be all the planets in our solar system (except Earth) along with the Moon.

What time to see the lineup? They will be seen leaving in a kind of parade. Starting at 1 am the planets will begin to rise: starting with Saturn, around 1:00 am in your local time; Jupiter can be seen from 3:00 am; Mars rises just behind the gas giant, at approximately 3:30 am; it follows Venus at 5:40 am and finally Mercury just before sunrise (6:00 am). The Moon will be seen almost immediately after Mars. Please note that the times mentioned are for June 23if you see on another day it may vary a bit.

If you want to see the formed (complete) lineup, you can watch from about 45 minutes before sunrise. (Credit: NASA).

Since Mercury is the last to leave, it is also the most difficult to see. In addition to not being the brightest, it comes out just before sunrise. On June 23 you will hardly be able to grasp it, if you watch tonight or the following ones you will have more opportunity since the past On June 16, Mercury reached its greatest western elongation. According to The Sky, the planet Mercury reached its greatest western elongation of 23.2 degrees relative to the Sun. That date was the best time to view Mercury as it appeared at its highest point above the horizon in the morning sky. Now you could also see it, but it will be much more complicated and you must be very attentive.

How and in what direction to see? To enjoy the event you just have to look up at the sky before dawn in the direction east-southeast. can be seen from any place, although you must consider the weather conditions: you need a clear sky and free of light pollution to enjoy it to the fullest. Also take into account the trajectory, time of departure and setting of the celestial bodies, you can help with a software or mobile application. Here you have a long list of applications for astronomy lovers.

What is a planetary lineup or parade? The planets are not actually aligned in space, which means that if you could see from “above” the solar system, they would appear spread out. However, to terrestrial observers they appear as if they are close to each other. From time to time the relative position of the stars in the sky is shown aligned from the Earth, in such a way that you could draw a line between them. As we mentioned, only our perspective occurs, and it rarely occurs with multiple planets.

According to Star Walk, although “planetary parade” is not an official term, it is used often and commonly these are the types of planetary parades:

  • Planets mini parade – 3 planets.
  • Little Planet Parade – 4 planets.
  • Grand parade of planets – 5 or 6 planets.
  • Full (grand) parade of planets – all the planets of the Solar System (+ sometimes Pluto).

How to see Neptune and Uranus? As we mentioned, these planets are not visible to the naked eye, so you need an observation team. By June 23, Uranus is between the Moon and Venus, while Neptune appears between Jupiter and Saturn.

If you don’t have a telescope, Saturn, Jupiter, Mars, Venus, Mercury and the Moon are available. It’s a one-time event, coincidences that rarely happen. Clear skies!
