Macassar – The planet Jupiter holds the title as the largest planet in the solar system. It turns out that the size of Jupiter is nothing when compared to other monster planets in the universe.
In addition to the array of planets in our solar system, there are other planets of various appearances and sizes in the universe. So what is the largest planet in the universe?
Quoted from detikINET, the gas giant planet Jupiter is about 11 times as wide as Earth. This planet holds the title of the largest planet when exoplanets were discovered, namely before 1992.
But the size of this Jupiter is nothing compared to the monster planets that were discovered after it.
As reported detikINET from Live Science, there are two measurements in considering the size of a planet. The first is the width (twice the radius) and the second is the mass.
In terms of width, the largest exoplanet has a radius roughly twice that of Jupiter. “This is an extreme object that orbits very close to its parent star,” said University of Geneva exoplanet researcher Solene Ulmer-Moll.
The width and mass of a planet are related. However, there is not always a direct correlation between the two.
This is because each planet has a different density. This means that some low-mass planets are able to ‘expand’ to a larger size than heavier exoplanets.
One example is the gas giant HAT-P-67 b which is 1,200 light years from Earth. This planet has a radius twice that of Jupiter. It currently holds the title of one of the largest planets in terms of width. However, its density is lower than that of Jupiter, only about a third of Jupiter’s mass.
Likewise with Planet Wasp-17 b which has about twice the width of Jupiter. Then there is also KELT-9b whose radius is 1.84 times Jupiter.
While rocky planets, in terms of size never come close to Jupiter. For example, the largest is called a “super-Earth” and is only twice as wide as Earth.
“By comparison, Wasp-17b has a radius equivalent to 22 Earths,” said Ulmer-Moll.
The most massive planet is about 13 times the mass of Jupiter. This includes the gas giant HD 39091 b, which is located 60 light years from Earth, and has a mass about 12.3 times the mass of Jupiter.
