The biggest planet in the Universe? Scientist reveals the answer, but it will surprise you

tech.hindustantimes.com:

In our solar system, we are aware that Jupiter is the biggest planet due to its size and mass however, beyond that there are several other planets that are far bigger. Unfortunately, under the current state of things, we cannot say for sure that there is one specific planet that is the biggest. In fact, there are several candidates there. The reason behind that is the uncertainty regarding their sizes and how we define a planet. Check out what Thayne Currie, an associate professor of physics and astronomy at the University of Texas, San Antonio said.

According to a Space.com report, Currie says that the largest planet ever known is called ROXs 42Bb. The size of the planet depends on numerous factors, however, planet ROXs 42Bb is known as the largest gas giant and its mass is 9 times that of Jupiter. The planet is located 460 light-years from Earth. Additionally, its radius is about 2.5 times larger than Jupiter's radius. The data of planet ROXs 42Bb was collected with the help of the Keck Space Telescope in 2013. However, Currie also has doubts about the planet being the largest due to other planets present with the same size or even larger.

Currie said, “There are a couple of planets that are actually protoplanets, so they're still being assembled. I would suspect those are actually larger.” He further talked about two protoplanets that orbit the star named PDS 70 located about 370 light-years from Earth that are two times larger than Jupiter. Planet HAT-P-67 also comes in the race as the largest planet since its radius is two times larger than that of Jupiter which is similar to ROXs 42Bb.
