Final answer:
The type of exoplanet not found in our solar system but commonly observed around other stars is called a Super-Earth.
Step-by-step explanation:
The type of planet revealed in surveys of exoplanets that we do not have in our solar system is known as a Super-Earth. A Super-Earth is a planet that has a mass and size between that of Earth's and Neptune's, which is absent in our solar system. According to astronomical observations, particularly those from the Kepler Space Telescope, these planets are more common than Jupiter-size gas giants in other planetary systems. The discoveries also include various other types of planets such as mini-Neptunes and hot Jupiters, but Super-Earths are notable for their absence within the context of our own planetary lineup.
