Creation Moment 8/10/2020 - And yet K2-25B Exists.....

"Surprisingly Dense Exoplanet Challenges Planet Formation Theories (NSF NOIRLab).
Another theory out of sync with observations concerns how planets form. K2-25B is a planet slightly smaller than Neptune, and it orbits an M-dwarf star.
This planet is “unusual” say these astronomers at the National Science Foundation’s National Optical-Infrared Astronomy Research Laboratory (NOIRLab).
Astronomers predict that giant planets form by first
assembling a modest rock-ice core of 5–10 times the mass of Earth and then enrobing themselves in a massive gaseous envelope hundreds of times the mass of Earth. The result is a gas giant like Jupiter. K2-25b breaks all the rules of this conventional picture: with a mass 25 times that of Earth and modest in size, K2-25b is nearly all core and very little gaseous envelope. These strange properties pose two puzzles for astronomers. First, how did K2-25b assemble such a large core, many times the 5–10 Earth-mass limit predicted by theory? And second, with its high core mass — and consequent strong gravitational pull — how did it avoid accumulating a significant gaseous envelope?
Of K2-25B, they say, “this exoplanet’s existence is at odds with the predictions of leading planet formation theories.And yet it does exist."
