Q: Who built them and funded them?
A: The spacecrafts were built at JPL and funded by NASA.
Q: What data did they collect about gas giants?
A: Both missions have gathered large amounts of data about the gas giants of the solar system, which was previously unknown before their launch.
Q: How has it been used to place limits on Planet X's existence?

Q: When did each probe leave our Solar System?
