One of the most interesting puzzles in the solar system is whether there is an undiscovered giant planet hidden far beyond Pluto. Known as "Planet Nine" or "Extraterrestrial Planet," this hypothesis has caused much controversy since it was first proposed. Mainly because it remains undiscovered. But a new study suggests that for some reason the elusive object was inadvertently observed as early as 1983.

Since the mid-19th century, astronomers have been searching for an undiscovered giant planet lurking outside the solar system. In early 2016, the study rekindled interest. The 2016 hypothesis about Planet Ninth, based on mathematical models and computer simulations, suggested that Giant Ninth exerted a gravitational effect on the ice in Neptune's upper layer.
These materials are called extreme Neptune extraterrestrial bodies (ETNOs) and have very long orbits, as explained in the simulations, under the gravitational pull of some larger object, these objects seem to be trapped in a similar pattern. According to the hypothesis, the planet requires 5-10 times the mass of the Earth and takes about 10,000 years to orbit the sun. Its orbit is about 560 astronomical units from the Sun, and from this point of view, the distance between the Earth and the Sun is only one astronomical unit, that is, 93 million miles or 150 million kilometers.
At such a distance, Planet Nine should be a dark, cold world with so little sunlight reflected that it's extremely difficult to spot. However, unless this hidden world is directly observed, its existence is always a guess. But the story of Planet Nine may take an interesting turn — more recently, based on data collected decades ago, new research may have uncovered traces of new mysterious worlds far from Neptune.
Michael Ron-Robinson, an astronomer from Imperial College London in the United Kingdom, analyzed about 250,000 points detected by the Infrared Astronomy Satellite (IRAS) in 1983 in search of Planet Nine. His research shows that of all the data he has rummaged through, only one case cannot be ruled out: objects that appeared and crossed the sky in June, July, and September 1983. Astronomers believe that while the object may be a new planet, its orbit could be a new ninth candidate because its orbit differs from what was predicted in 2016.
IRAS, which has been in operation for ten months, is the first astronomical telescope to make observations with infrared light, and it has achieved many unexpected achievements. Nearly 40 years later, it may have opened up a hidden world lurking on the periphery of the solar system. Illuminated by IRAS infrared light, those small, black objects look like potentially detectable planet nine.
The object is located in an awkward place near the Galactic Plane, a location that could also be used to explain why filamentous nebulae make noise when illuminated by infrared waves. However, if this were a new planet, it would be three to five times the mass of Earth, according to IRAS data, and would orbit the sun at a distance of 225 aurons from the sun, which is more accurate than the 2016 prediction for Planet Nine. Could this little dot be the elusive ninth planet? If so, it's the first large planet to be discovered in nearly two centuries. We need more time to discover, but it's exciting to think about whether it will open the door to a lifetime of research or make people happy. For now, research on Planet Nine is continuing, but most likely not for long.
The Infrared Astronomical Satellite, or Infrarood Astronomische Satelliet (IRAS) in Dutch, was the first space telescope to observe the entire night sky at infrared wavelengths. [6]
It was launched on January 25, 1983, and the mission lasted 10 months. [7] The telescope is a joint project of the United States (NASA), the Netherlands (NIVR), and the United Kingdom (SERC). More than 250,000 infrared light sources were observed at wavelengths of 12, 25, 60 and 100 microns. [7]
The California Institute of Technology's Center for Infrared Processing and Analysis supports the processing and analysis of IRAS data. The IPAC's Infrared Science Archive currently holds archives of IRAS. [8] [9]
The success of IRAS sparked interest in the mission of the Space Shuttle Infrared Telescope (IRT) in 1985, as well as in the already planned Space Shuttle Infrared Telescope equipment, which eventually became the Spitzer Infrared Space Telescope Equipment: SIRTE, which later evolved into the Spitzer Space Telescope and was launched in 2003. [10] The success of early infrared space astronomy laid the groundwork for later inventions such as the Infrared Space Observatory (1990s) and the Hubble Space Telescope's NICMOS instrument.
