Is it time to head back to Neptune and its moon Triton? It might be. After all, we have some unfinished business there.
It’s been 30 years since NASA’s Voyager 2 spacecraft flew past the gas giant and its largest moon, and that flyby posed more questions than it answered. Maybe we’ll get some answers in 2038, when the positions of Jupiter, Neptune, and Triton will be just right for a mission.
Astronomers are increasingly interested in Near-Earth Objects, or NEOs. There are ongoing efforts to find them all and catalog them all, and to find out which ones might pose a collision threat. Now some astronomers with the NASA-funded Catalina Sky Survey have found a new, tiny, temporary moon for Earth.
