I’m curious if there are any theories to why these planets haven’t been noticed yet?
Perhaps the surface is black and light-absorbing?
Maybe aliens have concealed it and use it as a base - they’re awful waskally...
One of the basic reasons why these huge planets have not been as of yet discovered has to do simply with the huge distances in which these planets orbit the sun. With planets closer to the sun, it is easier to locate them due to the fact that they reflect sunlight back to us. But in cases where the planets, while they may be huge, the ability to spot them via reflection of sunlight has been severely diminished due to the huge distances in which these planets orbit around the sun far greater than the furthest planets like Pluto. So lack of reflected sunlight is the number one reason these planets remain unknown. There are other indications of a huge planet way out there due to affected asteroids and other objects that do not follow the flight plain simply based on what we have. And so , the unpredictable orbits are being blamed on the giant planet yet remains unseen due to lack of reflective sunlight.
