So far only one extrasolar planet has officially been confirmed as rocky, but many dozens are assumed to be rocky. This is because a planet must have both its size AND its mass measured to confirm it as rocky or gaseous, but almost all extrasolar planets have only had their masses measured due to the technical difficulties of measuring a distant planet's size. Most planets significantly less massive than Neptune are assumed to be rocky.
