Question

Quizplus · Accepted Answer

Our most detailed knowledge of Uranus and Neptune comes from spacecraft exploration, particularly the Voyager 2 mission in the 1980s which sent back close-up images and data on the two planets. The Hubble Space Telescope has also contributed to our understanding of these planets, but not to the same extent as spacecraft missions. Ground-based telescopes, both visual and radio, have limited capacity to gather detailed information on Uranus and Neptune due to their distance and dimness. Manned missions have not been sent to these planets. Our most detailed knowledge of Uranus and Neptune comes from spacecraft exploration, such as the Voyager 2 mission in the 1980s which provided the closest flybys and the most comprehensive study of these planets to date.
