Fulton gap

The Fulton gap (also the radius valley)^{[citation needed]} is the 2017 discovery that it is uncommon for planets to have a size between 1.5 and 2 times that of Earth.^[1]^[2] The Fulton Gap is named after Benjamin J. Fulton, who first described the phenomena in his doctoral thesis, for which he won the Robert J. Trumpler Award.^[3]^[4]

..., refined studies of the distribution of planets within the 1 – 4 R_🜨 range have revealed a significant drop in the population, or "Fulton gap" between 1:5 – 2:0 R_🜨(Fulton et al. 2017) (Owen & Wu 2013), which is not yet well-understood.
