GJ 3090 b's orbit identified as retrograde

Astronomers have discovered an unusual exoplanet the size of Neptune moving in the opposite direction to its star's rotation. One.uz reports this.

The discovery of this object, named GJ 3090 b, could lead to a reassessment of theories regarding how planetary systems form. Retrograde orbit and its characteristics An international team of researchers detected the planet using a high-precision spectrograph.

Observations showed that GJ 3090 b has a retrograde orbit. Its orbital axis is tilted by approximately 136 degrees.

As a result, the planet moves in the opposite direction to its star's rotation. Such a case is considered one of the first observed instances around small and relatively cool stars.

Typically, planets form from the gas and dust disk that creates their star. Because of this, in most cases, they move in accordance with the star's rotation.

Formation mechanisms Scientists studied the system in detail to determine why GJ 3090 b ended up with such an unusual orbit. Researchers initially hypothesized that another large celestial body might have altered the planet's direction of motion.

However, no such object was detected during observations. Subsequently, scientists proposed another possibility.

They believe that during the early stages of the planetary system's formation, another gas and dust disk may have been pulled in from outer space. It is possible that materials in this disk later influenced the planet's orbit, changing its direction of motion.

Researchers plan to continue observing the GJ 3090 b system. They hope to determine how common such retrograde orbits are around red dwarfs and how the external environment affects the formation of young planetary systems.<
