New Giant Planet Is Evidence of Possible Planetary Collisions A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash. TOI-1853b’s mass is almost twice that of any other similar

Wouldn’t the gravitational pull of this planet be massive due to it’s high density? I’d wager internally it is probably molten due to sheer density and pressure and then the core is a solid ultra dense ball of material. Just my conjecture though.
