Correction, rogue planets are detected when their gravity causes micolensing of distant objects (stars), not the other way around.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rogue_planet#Observation" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rogue_planet#Observation</a><p>Not an astronomer, but my impression is that microlensing couldn&#x27;t be used to detect objects in our own solar system, but I don&#x27;t see any reason why eclipsing of distant stars couldn&#x27;t be used... it would be far too rare to be practical to find a planet, though.
