A heavenly encounter

There is only a small chance that the planets will appear to an observer from Earth to be clustered together in a small patch of sky. In the following days, right after sunset, you can experience such a rare moment

These days a spectacular meeting is taking place in the sky. All five visible planets appear clustered in the western sky just after sunset. Venus and Jupiter are the most prominent, among them you can distinguish Mars and Saturn, and low, close to the horizon, the star Mercury twinkles. All five are arranged in a straight line inclined at an angle to the western horizon, towards the south. This arrangement is required by the movement of the planets in what is called the milka plane (from eclipse), a plane common to their almost circular orbits around the sun. Venus and Mercury are always seen near the Sun, switching roles every few months between the dawn and evening stars. This is because their orbits are closer to the sun than Earth's. The other three planets, on the other hand, move in outer orbits, so they can be seen in different celestial locations. Each planet (planet) has its own cycle, and the times they orbit the sun vary from two months (Humper) to 30 years (Saturn).

The behavior of the planets in the sky is similar to that of elevators in a large hotel. At a given moment, the elevators will be scattered randomly over all the floors, some going up and some going down, and only very rarely will they all come together to the ninth floor, for example. So are the planets: there is only a small chance that they will appear to an observer from Earth grouped together in a small piece of sky. The next time an event of this kind, which is now visible, will occur in 2040. Astronomers predict that the appearance then will be much less successful due to being too close to the sun, and therefore it is better
not to wait

The best time to watch the celestial spectacle is right after sunset, at eight o'clock. Then Hema will set beyond the horizon. You have to find an observation point open to the western horizon, on the seashore or on a high roof. A clear, cloudless sky will allow a perfect view, including of the planet Mercury, which people rarely see. The observation can be made any day from now until mid-May. Of particular interest will be the very close meeting of four of the five planets between May 5 and 10, with Jupiter slightly different, higher in the sky. On May 15-13, the sickle of the moon also joins the celebration. You can find details on the Internet, for example at http://www.cranbrook.edu/institute/

The planets differ from all other stars in that they change their relative position in the sky. This is beyond the daily "movement" of sunrise and sunset caused by the rotation of the earth on its axis, and which is common to all elements of the sky. What sets the planets apart is that they are small, cold bodies that surround our sun, similar to the Earth itself. Their distance from us is relatively small: the time needed for a beam of light or a radio transmission to reach them is measured in minutes to hours. The rest of the stars that we see in the sky, and are called Shabbat stars, are hot balls of fire similar to the sun, and their distance from us is at least ten thousand times greater, between a few light years and thousands of light years.

Due to their uniqueness, the planets attracted the hearts of the ancients, and they attributed divine qualities to them. Their conventional names are derived from the Roman version of the Greek gods - Mercury (Heat planet), Venus (Venus), Mars (Mars), Jupiter (Zephus) and Saturn (Saturn). The changing position of the planets among the constellations or zodiac signs inspired many generations of astrologers, who pointed out a possible connection between the celestial configuration and earthly events. A heavenly meeting such as the one taking place now may be interpreted as a harbinger of a wonderful or bitter fate. But as far as scientists know, there is no mechanism that allows the small and distant planets to affect us in any way, by gravity, radiation or in any other way.

In ancient times there were seven planets: the five described above, as well as the sun and the moon. This is because when viewed from Earth, the last two are also seen to change their position frequently in the sky. In fact, it is the change in the observed position of the sun between the stars of the Sabbath that defines the luck attributed to each month. This fact is known only to a few of those who seriously discuss being born under the sign of Scorpio or Libra. The symmetry was broken due to the discoveries of Galileo and Copernicus, who made it clear that the sun is at the center of the system, and that its annual "movement" is caused by the fact that the earth orbits it. The moon also lost its honorable place as a planet, since it is now known that it only orbits the earth.

As compensation, three new planets were discovered in the 18th to 20th centuries: Uranus, Neptune and Pluto, which can only be seen with a telescope. This is how nine planets orbiting the Sun are counted today, including the Earth itself. The fact that our lives are on a tiny cosmic "grain", which surrounds a huge sun, and is found in a galaxy containing a hundred billion other suns, is known to be of great importance in clarifying our place in the universe. One of the most exciting developments in the last decade is the discovery of conclusive evidence for the existence of planets around other suns in the galaxy. It is possible, therefore, to assume that if there are beings who think about some of these extrasolar planets, they too may occasionally watch a spectacular spectacle of an encounter of the kind we see now.
