   Why we study Neptune. Neptune, along with its cousin Uranus, is the least-explored planet in our solar system, having been visited by a spacecraft only once. Yet we’ve found more Neptune-sized worlds orbiting other stars than any other type of planet. In order to understand other solar systems and figure out whether our own is unique, we need ...

   Why do we study Neptune?

   • The majority of worlds we’ve found around other stars are Neptune-sized. By studying Neptune we learn about other solar systems and whether or not ours is unique. Neptune, along with its cousin Uranus, is the least-explored planet in our solar system, having been visited by a spacecraft only once.

   Is Neptune a good planet to study?

   • This planet, like its fraternal twin Uranus, is one of the least explored planets in our Solar System, only briefly visited by Voyager 2 in 1989. Its extreme distance from Earth makes it extraordinarily difficult to study with even the world’s largest telescopes, but efforts to study Neptune are well worth the investment.
