According to the forecasts of astronomers, on 4 July 2020, will last a rare and unique celestial event known as harmonic convergence. Explain what kind of Parade, when and how it will happen and how to see it.
What is the parade of planets?
The official scientific term “parade of planets” does not exist, but this name is widely used in astronomy. This name to describe an astronomical phenomenon, which occurs when the planets of the Solar system lined up in a row in the same region of the sky as it is visible to observers on Earth.
Very soon, observers will be able to witness this unique parade of planets. They will have incredible chance to see all planet in one night. In the beginning of the month the elusive planet mercury appears in the morning sky. Brilliant Venus will be next. Mars red, distant Uranus and Neptune, also gas giants Jupiter and Saturn – will all be available for observation. Even the dim the dwarf planet Pluto will offer observers a favorable setting for viewing.
Types of planetary parades vary according to the number of planets involved:
- A mini-planetary parade – 3 planet.
- The parade of minor planets – 4 planets.
- Great planetary parade – 5 or 6 planets.
- Large (full) parade of the planets – all the planets of the Solar system (+ sometimes Pluto).
A mini-parade of planets is a pretty common event. Three planets can be observed simultaneously in the same part of the sky several times a year.
When lining up the planets of the Solar system
It is important to note that the planetary alignment during the parade of planets should not be taken literally. In fact, they never aligned one perfectly straight line, as is usually shown in figures. As the planets of the Solar system is not all rotate in the same plane and moving in different orbits in three-dimensional space, they will never be perfectly aligned.
What to see during the parade of planets
Under the alignment, or the parade of planets, astronomers usually mean that the planets will appear in the same part of the sky. Sometimes the position of the planets in the sky line, but this is not always the case. Often two or three planets form a line in the sky.
In addition, much depends on the point of contemplation. When the planets are on one side of the Sun, they are not necessarily in the same area of the sky for observers from Earth. Conversely, when the planets are in the same part of the sky from the point of view of the Earth, they are not necessarily aligned with the point of view of the Sun.
What is the planetary alignment is expected on 4 July
According to forecasts, July 4, 2020 will be rare and unique alignment of the planets. All the planets of the Solar system – mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune plus the dwarf planet Pluto – lined up on one side of the star at the same time. It will be a parade of planets first type of the three described above. Will be almost perfect alignment, the deflection angle will be quite small.
Last parade of planets of this type occurred in 1982 and the next is expected in 2161 and 2492, respectively.
How to see a parade of planets
Parade of planets, which will be held almost the whole of July, to be observed fully.
Uranus with Neptune are too far away, and from this distance the naked eye can not see them. Saturn, Jupiter and Mars will be visible during the day, and Venus in the morning. Mercury, in turn, is close to the Sun, so the star completely outshines it.
If the person was able to leave the Solar system for several billion kilometers away, at that distance one could observe how the planets are grouped in one direction. Unfortunately, to expect that from the roof, balcony or in open areas will be available planets in the classical sense is not necessary.
It is worth noting that the planets in the sky are moving slowly, so gradually form a parade. Accordingly, people will have the opportunity to observe this phenomenon for about two weeks. Planets, in contrast to solar and lunar eclipses not occur at exactly the specified time.
