Not Jupiter, This is the Biggest Planet in the Universe

The following is the translation of the text from 'Bahasa' to 'English' while preserving any html tags: "Astronomers have discovered a planet that is twice the size of Jupiter and has a mass more than 10 times that of it."

Astronomers have discovered a planet that is twice the size of Jupiter and has a mass more than 10 times greater. When astronomers first observed the outer solar system thirty years ago to find exoplanets, our knowledge of the width and mass arrangement of planets in the Milky Way became clear. However, how big are these planets, and is there a largest planet in the entire universe?

"Before 1992, Jupiter occupied the position of the largest planet, which had a size approximately 11 times the width of Earth"

"In the measurement of planets, there are rules followed by scientists. At least, there are two aspects that are considered, namely width (twice the radius) and mass."

"Recently, a planet with dimensions exceeding Jupiter has been revealed. This largest extraterrestrial planet has a radius approximately twice that of Jupiter. Solene Ulmer-Moll, a postdoctoral researcher in the field of extraterrestrial planets from the University of Geneva, conveyed this information to Live Science via email. 'This is an extreme object that orbits very close to its parent star,' explained Ulmer-Moll."

"The density of planets varies."

The relationship between width and mass of planets is interconnected, but there is not always a direct correlation between the two. This is caused by the variation in planet density, which means that some low-mass gas giant planets can 'expand' and reach larger sizes compared to other heavier exoplanets.

Who is He/She?

The gas giant named HAT-P-67 b, has a radius that is approximately twice the size of Jupiter, is now considered one of the largest known planets in terms of width. Nevertheless, this extraterrestrial planet, located 1,200 light-years away from Earth, has a very low density. Therefore, Ulmer-Moll stated that this planet only has about one-third of Jupiter's mass.

Planet with the label WASP-17 b has a width about twice that of Jupiter. KELT-9b is in second position, with a radius 1.84 times that of Jupiter. Most rocky planets in other locations never reach the size referred to as 'super-Jupiter' above.

The largest rocky planet, called 'Super-Earth', has a size about twice the width of Earth.

"As a comparison, Wasp-17b has a radius equivalent to 22 times that of Earth," said Ulmer-Moll.

Although rocky planets have higher density compared to gas giants, they still have a lighter mass than gas giants. This is because when rocky planets form, they gradually accumulate gas, ice, and water, transforming them into gas giants with rocky cores, he revealed. The heaviest planet has a mass about 13 times that of Jupiter. One of them is the gas giant HD 39091 b, which is located 60 light-years away from Earth and has a mass of about 12.3 times the mass of Jupiter.

"Failed Star?"

We do not expect to find a planet much larger than this super-Jupiter. This is because a planet can turn into a 'brown dwarf' or brown dwarf after reaching a certain size and mass limit. 'Brown Dwarfs' are often referred to as failed stars because they are heavier than super-Jupiter but not massive enough to trigger regular hydrogen fusion in their core. However, there is still something smoldering in the heart of a 'brown dwarf'.

"The main difference between 'brown dwarf' and a planet is their mass and the occurrence of deuterium—heavy hydrogen—burning."

Nolan Grieves, postdoctoral researcher at the Department of Astronomy, University of Geneva, to Live Science via email.

"In larger masses, an object will have pressure and internal temperature high enough to ignite most of the deuterium initially present in the object,"

add Nolan Grieves.

Redefinition of the differences between planets and brown dwarfs emerged in the 1990s.

The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "The distinction is estimated to be at a maximum limit of 14 times the mass of Jupiter, which means that the planet should not exceed this limit."

"There are planets that we have measured their mass to be approximately 13 times the mass of Jupiter within the uncertainty of the measurement, such as HD 39091 b and HD 106906 b, and it can be said that they are the largest known planets."

The largest failed star ever discovered is SDSS J0104+1535, located on the edge of the Milky Way and approximately 750 light-years away from Earth. Despite having a size 90 times that of Jupiter, this failed star has a radius ranging from 0.7 to 1.4 times that of Jupiter. Therefore, the most massive 'brown dwarf' may actually be smaller than the largest planet in our solar system.
