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.
There are 5 rocky planets in our solar system if you count Pluto. If not, there are 4 rocky planets in the solar system.
4 rocky planets
The surprising thing to me is how MANY extra-solar planets have been discovered. Considering the limitations of the Kepler Space Telescope's design, this indicates that there may be planets around a majority of the stars.
The planets in our Solar System that are rocky are Mercury, Venus, Earth, and Mars. These inner planets are also called "Terrestrial Planets."
The first four planets from sun Mercury, Venus, Earth and Mars are rocky planets other planets in solar system are gaseous or dusty planets.

Extra solar planets are planets that is outside of our solar system.
yes, for example us and the rest of the planets in the solar system. to date there are also approx 400 extra solar planets discovered (planets beyond our solar system)
