Free floating planets as a research area focuses on the detection, characterization, and population statistics of planetary-mass objects that are not gravitationally bound to any star. This field integrates microlensing surveys, deep infrared imaging, and dynamical modeling to constrain their occurrence rate, mass function, and spatial distribution in the Galaxy. Research addresses their formation pathways (e.g., ejection from planetary systems versus isolated collapse), atmospheric and interior properties at very low irradiation, and implications for planet formation theories and cluster dynamics. It also explores their contribution to the Galactic mass budget and the potential overlap with brown dwarfs and other substellar free-floating objects.
The JWST continues to live up to its promise by revealing things hidden from other telescopes. One of its lesser-known observations concerns free-floating planets (FFP). FFPs have no gravitational tether to any star and are ...

Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations where life might arise. Perhaps life can be found on the moon of a hot Jupiter or lingering in the ...

When 'Oumuamua traversed our solar system in 2017 it was the first confirmed Interstellar Object (ISO) to do so. Then in 2019, Comet 2l/Borisov did the same thing. These are the only two confirmed ISOs to visit our solar ...
