GJ 9827 hosts a $1.62\\pm0.11$ $R_{\\rm \\oplus}$ super Earth on a 1.2 day period, a $1.269^{+0.087}_{-0.089}$ $R_{\\rm \\oplus}$ super Earth on a 3.6 day period, and a $2.07\\pm0.14$ $R_{\\rm \\oplus}$ super Earth on a 6.2 day period. The radii of the planets transiting GJ 9827 span the transition between predominantly rocky and gaseous planets, and GJ 9827 b and c fall in or close to the known gap in the radius distribution of small planets between these populations.
