Jupiter, the largest planet of the solar system, will be on a straight line with the Earth and the Sun on September 26, 2022 at 23:10 Baku time, and at that moment it will be at the closest point in its orbit to the Sun - perihelion.

According to the information provided to APA by the Department of Astrophysics of Baku State University (BSU), such placement of celestial bodies occurs approximately every 12 years, and this event is called "the great clash of Jupiter" in science.

Jupiter will be at perihelion on January 19, 2023.

The main feature of the "Great Confrontation" is that during this event, Jupiter approaches the Earth at a minimum distance of 3.95 AU or 591,295,396 km, Jupiter's angular size is 49.87, and its brightness is almost -2.94 stellar magnitudes. contane.

Jupiter will be the third brightest object in the night sky after the Moon and Venus.

The last time such conflict took place on September 20, 2010.

After the event that will take place on September 26, it will be possible to observe the closest approach on October 1, 2034.

Astronomical opposition means that the planet is on the opposite side of the Sun relative to the Earth.

At the time of the encounter, the planet is 180 degrees from the Sun in the sky when viewed from Earth, that is, when the Sun sets in the west, the planet appears on the horizon in the east.

If the opposition occurs when the planet is near the perihelion of its orbit, such an astronomical event is called a "great opposition".

Planets whose orbits are outside the Earth's orbit can be in opposition.

For the collision event to occur, the Earth must be between that planet and the Sun.

Planets that may be in conflict are: Mars, Jupiter, Saturn, Uranus and Neptune.

Apart from planets, comets, asteroids and some other objects of the solar system can also be in conflict.

The most famous conflict is the full moon event.


A typical opposition of the planets occurs about once a year, when the Earth reaches the right configuration between the Sun and the planet.

A regular opposition of Jupiter occurs every 13 months.

The only exception is Mars.

The orbit and orbital speed of the red planet are very close to the corresponding parameters of the Earth, so our planet "passes" Mars only once every 27 months.

For this reason, the opposition of Mars occurs approximately every 2-3 years.

Mercury and Venus lie within Earth's orbit, so we will never see them in opposition.

Jupiter has been known to people since ancient times.

In the culture of Mesopotamia, the planet was called the "White Star".

A detailed description of Jupiter's 12-year cycle has been provided by Chinese astronomers, who named the planet "Star of the Year".

The Greeks called it the "Star of Zeus".

The "great opposition" is considered the best time to observe Jupiter from Earth.

At this time, due to the large visible angle of the planet, it is possible to distinguish more details on its surface.

Jupiter's disk has dark cloud bands and spots parallel to the equator, the appearance of which changes every year: small spots appear and disappear, colors, eddies change their shape.

Astronomers have been observing the Great Red Spot for 362 years.

The Great Red Spot is the uniquely long-lived and most massive hurricane in the Solar System.

The spot moves parallel to the planet's equator.

This longest-lived cyclone is significantly larger than the Earth - it is 30 thousand km long and 15 thousand km wide.

100 years ago, the spot was twice as big as it is today.

Jupiter will be visible in Baku on September 26 from 19:19 to September 27 at 05:54.

Its observation will be possible from 7:19 p.m. after rising 7° above the horizon in the east.

At 12:36 a.m. on September 27, Jupiter will reach its highest point in the sky.

Jupiter will no longer be visible when it is below 7° on the western horizon around 05:54.
