When to Use the Rogue Planets 3D Explorer
freetoolonline.com editorial team
Open the Rogue Planets 3D Explorer when your question is about planets with no host star at all - not planets that still orbit one.
When the rogue-planets explorer answers your question
Students and teachers introducing how astronomers detect objects that emit no light of their own, readers who want to see why a starless planet's microlensing event is so much shorter than a normal one, anyone curious about the real OGLE-2016-BLG-1928 record event, and readers who want the 2011-versus-2017 population-estimate revision explained side by side all get a direct answer here.
When to reach for a different microlensing explorer instead
Skip this page if your question is about a planet that still orbits a visible host star - the Gravitational Microlensing Exoplanet 3D Explorer covers that case, where the planet only adds a short secondary spike on top of the star's own multi-week brightening event. It also does not compute a specific real observed light curve or resolve the population-estimate debate on its own - use it to understand why the absence of a host star is itself the detection signature, then walk through the controls in the step-by-step guide.
