Answer:

A much greater variety of planets has been found around other stars than exists in our solar system. Large Jupiter-sized planets ("hot Jupiters") have been found orbiting close to their stars, which challenges our simple view of planetary system formation. There are also super-Earths and mini-Neptunes, planets intermediate in size between the terrestrial and jovian planets in our solar system and a number of exoplanets have eccentric orbits, unlike the planets of the solar system.
