Another "parade" of the planets of the solar system in 2024.
Abstract
A planetary parade is an astronomical phenomenon when a certain number of planetary bodies in the Solar System are located on one side of the Sun in a sector less than 90° and close to each other in the celestial sphere. There are three types of parade of planets: small, large, and full "parade". It was agreed that we are dealing with a small parade when at least four large planets are located on one side of the Sun in an angular sector of less than 90°. An astronomical phenomenon in which six planets are in a small sector on the same side of the Sun is called a big one. And if all seven planets are on the background of the starry sky on the same side from the Sun in a small sector, then such a parade is called big. Also, "invisible" and "visible" parades of planets are distinguished. We are dealing with a visible parade of planetary bodies when the planetary configuration of five planets of our solar system visible to the naked eye become visible simultaneously in the sector up to 40° during their movement across the celestial sphere. These planets are Mercury, Venus, Mars, Jupiter, and Saturn. And this is possible only when, for example, in Ukraine, Mercury and Venus are in eastern elongation in spring, and in autumn - in western elongation from the Sun. If two other giant planets – Uranus and Neptune – fall into such a sector in the celestial sphere, then we will be dealing with the so-called "invisible" type of parade of planets. The next "parade" of planets will take place in May 2024. Then the convergence of the extreme links of the "chain" of the location of the large planets will be separated by almost 71°. But it will be impossible to observe it throughout the area. After all, Venus and Jupiter will be almost next to the Sun at that moment.
