“He wanted to know about the solar system, he wanted to know all things about science, and he knew the dinosaurs’ names,” she said, chuckling.

In addition to these two impacts, existing evidence suggests three smaller asteroids also hit Earth during this time -- the late Eocene epoch -- pointing to a disturbance in our solar system's asteroid belt.

This explains why both Uranus and its solar system neighbor, Neptune, have magnetic fields very different from the one we experience on Earth.

These are just two proposals that planetary scientists have come up with for what lies beneath the thick, bluish, hydrogen-and-helium atmospheres of Uranus and Neptune, our solar system's unique, but superficially bland, ice giants.

Astronomers have detected more ice giant-sized bodies outside of our solar system than any other kind of exoplanet.
