One of the most massive exoplanets to be ever discovered sits 300 light-years from Earth in the Great Bear constellation. Astronomers in Poland have found an oversized exoplanet which is more than 11 times the mass of Jupiter.

It is a cold super Jupiter, meaning it is extremely cold and much larger than Jupiter. The exoplanet and its features were detailed in a paper published last month in Astronomy &amp; Astrophysics.

It resides in a multi-planet system which is a little over 300 light-years away from Earth. The host star of the exoplanet is about 20 per cent more massive and twice as large as our Sun. Named HD 118203, it is also older than our star.

The star system also hosts a hot Jupiter, which is twice the size of Earth. It was discovered in 2005 by the Transiting Exoplanet Survey Satellite (or TESS).

The system continued to intrigue astronomers after the hot Jupiter was found there. Researchers say they knew it had to host another planet, and therefore they studied it.&nbsp;

“Doppler observations, however, indicated that this was not the end of the story, that there might be another planet out there,” Andrzej Niedzielski, an astronomer at Nicolaus Copernicus University in Poland, said in a university release. “Therefore, we immediately included this system in our observational programs.”

<h2>Another planet in star system</h2>

They used TESS data and measurements from Telescopio Nazionale Galileo and Texas' Hobby-Eberly telescope to study the system and soon realised that there was another planet orbiting the star.

However, the planet is not visible because of the star's brightness. They concluded it exists based on the radial velocity data that caused the star’s brightness to slightly change over time.

The orbit times of both planets are also extremely different. While the hot Jupiter found in 2005 completed one orbit in six days, the cold super Jupiter takes 14 Earth years for the same.

The newly discovered super Jupiter is not the biggest exoplanet. TrES-4b, about 1,430 light-years away in the constellation Hercules, has that title. It is 230,000 kilometres across compared to Jupiter’s 142,700 km radius.&nbsp;

Beta Pictoris b, which is about 12 times the mass of Jupiter and 63 light-years away from Earth, is the nearest in size to the newly found exoplanet.

Cosmic giant 300 light-years away in Great Bear is 11 times more massive than Jupiter

James Webb Space Telescope, which is the largest and most powerful telescope ever launched into space, spotted a "super Jupiter" around a neighbouring star — and it has a super orbit. The exoplanet is the 12th closest exoplanet to Earth known to date. It is also the closest planet bigger&nbsp;than Jupiter.&nbsp;

The National Aeronautics and Space Administration (NASA) said that the planet, Epsilon Indi Ab, is one of the coldest exoplanets observed to date.&nbsp;

The planet is roughly the same diameter as Jupiter but with six times the mass. The big difference is that it takes this planet more than a century, possibly as long as 250 years, to go around its star. Its atmosphere is also rich in hydrogen similar to that of Jupiter.&nbsp;

An international team of astronomers observed Epsilon Indi Ab using the coronagraph on Webb's MIRI (Mid-Infrared Instrument). The feat is extraordinary as the exoplanet has been directly imaged and only a few tens of exoplanets have been directly imaged previously by space- and ground-based observatories.&nbsp;

The exoplanets that have been previously photographed are often the hottest and youngest, still emitting a significant amount of energy from their initial formation. Planets get fainter and more difficult to image as they cool and contract during their lifetime.&nbsp;

The research article, titled "A temperate super-Jupiter imaged with JWST in the mid-infrared" was published in the journal Nature on Wednesday (Jul 24).&nbsp;

As quoted by NASA, Elisabeth Matthews, a researcher at the Max Planck Institute for Astronomy in Heidelberg, Germany, said: "This discovery is exciting because the planet is quite similar to Jupiter — it is a little warmer and is more massive, but is more similar to Jupiter than any other planet that has been imaged so far."&nbsp;

Matthews further explained, "Cold planets are very faint, and most of their emission is in the mid-infrared. Webb is ideally suited to conduct mid-infrared imaging, which is extremely hard to do from the ground. We also needed good spatial resolution to separate the planet and the star in our images, and the large Webb mirror is extremely helpful in this aspect."&nbsp;

Caroline Morley of the University of Texas at Austin, who is a team member, said, "Our prior observations of this system have been more indirect measurements of the star, which actually allowed us to see ahead of time that there was likely a giant planet in this system tugging on the star. That's why our team chose this system to observe first with Webb."&nbsp;

James Webb spots 'super Jupiter' and it is one of the coldest exoplanets observed to date

New research suggests that Alpha Centauri could host a Super Jupiter in a stable orbit. The research into it has been done by Tinglong Feng, an undergraduate at Xi’an Jiaotong University in China. Feng took up the three-body problem which has been a cosmic issue. The problem causes gravitational interactions between the bodies causing instability, and making the movements of the three bodies extremely difficult to predict.&nbsp;

When a planet orbits two stars, it creates a three-body problem, but one that can also be called a “restricted three-body problem". Some potential stable orbits can exist in such a scenario for a planet.

Feng studied Centauri AB, the nearest binary neighbour to our world and tried to understand whether a super Jupiter can exist in the system and the orbit it might have.&nbsp;

“The three-body problem, which seeks stable orbit configurations among gravitating bodies, is a longstanding challenge in celestial mechanics,” Feng writes.&nbsp;

“As the closest triple stellar system to Earth, Alpha Centauri system has attracted diverse studies in astronomy, including exoplanet stability,” Feng writes.&nbsp;

Even though the entire Alpha Centauri system is a triple star system, the third star is far enough from Centauri AB to let them qualify as a binary system, Feng writes.

Feng compared the Centauri AB system with a similar star system named GJ65AB (Gliese 65) only about 8.8 light-years away from Earth. This star system is binary and hosts an exoplanet of the mass of Neptune. Feng says that despite Gliese 65 being a pair of M-dwarfs, the system “shares similar mass ratios and orbital eccentricities".&nbsp;He ran simulations of the Centauri AB system to get a clear picture of whether the system can host an exoplanet.

“The similarities between GJ65AB and Alpha Centauri AB, together with the newly detected stable super Neptune in the GJ65 system, suggest the stability of the corresponding potential super Jupiter in Alpha Centauri AB,” Feng writes.&nbsp;

<h2>Gliese 65 and the Alpha Centauri AB systems</h2>

He theorises that if Gliese 65 and the Alpha Centauri AB systems are similar, and if GJ65 can host a planet in a stable orbit, can the same be true for Centauri AB?

He then went on to find stable orbits for a planet orbiting Centauri AB. Feng identified Centauri A as the primary star and placed a planet with the mass of 350 Earths at a distance of 23.336 AU, keeping others parameters similar to GJ65. “We figured out the stable zone spanning from 0.1 to ~ 2.2 au, and ranges from 0 to 0.5,” Feng writes.

“From this hypothesis, together with the newly detected Neptune-mass planet in the GJ65 system, which is similar to Alpha Centauri AB, we assume the existence of a potential Jupiter-mass planet with corresponding orbital parameters in Alpha Centauri AB should also be possible,” Feng writes.

So far, no planets have been found around Centauri AB, but Proxima Centauri, which lies near it, has two confirmed exoplanets. Notably, scientists have noticed signs of a planet being in Alpha Centauri A.
