Some explain it my underdetected matter out there
while others are saying it is new physics.

New physics? Then why don't comets drift off course?

They do. Outgassing adds random changes of
course far greater than the anomaly. However,
the planets do not seem to be affected at the
same level of acceleration. For explanations
such as drag where the force depends on
cross-sectional area while mass depends on
volume, the effect could be so small as to be
undetectable hence is still difficult to rule out.
