Probably not, there's not enough microlensing events for MACHOs to be responsible for more than about 5% of dark matter IIRC.Tanelorn said:Interesting news about planets with no orbit:

Perhaps enough mass to explain dark matter?
A planet with no orbit is a celestial body that does not revolve around a star or any other object in a predictable path. This means that it does not follow the usual elliptical orbit that most planets in our solar system do.
There are a few theories about how planets with no orbit form. One possibility is that they were once part of a larger object, like an asteroid or comet, that was disrupted by an impact or gravitational forces. Another theory is that they were formed in a similar way as stars, through the collapse of a gas cloud, but were not able to gather enough mass to become a star.
No, there are no confirmed planets with no orbit in our solar system. However, there are several objects that have been classified as "rogue planets" which do not have a stable orbit around a star. These objects may have been ejected from their original planetary system and are now drifting through space.
Planets with no orbit are difficult to detect, as they do not emit light or have a predictable location in the sky. However, they can be indirectly detected through their gravitational effects on nearby objects, such as stars or other planets. Scientists also use advanced telescopes and techniques, like microlensing, to search for these elusive objects.
Studying planets with no orbit can provide valuable insights into the formation and evolution of planetary systems. It can also help us better understand the dynamics of objects in space and the effects of gravity. Additionally, these objects may have unique compositions and characteristics, which can expand our knowledge of the diversity of planets in the universe.
