Fulton gap

The Fulton gap 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 signifcant 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.

One recent discovery also shows that there are significantly fewer planets that are between 1.5 and 2 times the size of Earth than those either smaller or larger than that. This drop, called the Fulton gap, could be what distinguishes the two types of planets from each other, researchers say in their study of the discovery, published in 2017.
