We don't know anything about planets around very young stars because the radial velocity method doesn't work with them,
We do not know if planets like those in our solar system are able to form in the highly energetic, dynamic environment of these massive stars, but if they could, their existence would be a short and exciting one.
Asteroids are the leftover building blocks of rocky planets like Earth. We can't directly see other terrestrial planets, but now we can study their dusty fossils.
