Question

Quizplus · Accepted Answer

Many extrasolar planets, especially those discovered through the radial velocity method, have been found to travel on very eccentric orbits. This is in contrast to the relatively circular orbits of the planets in our solar system, which can be attributed to the different formation environments or dynamical interactions in extrasolar systems.
