The great majority of the known asteroids move in orbits between those ofMarsand Jupiter. Most of those orbits, in turn, have semimajor axes, or mean distances from the Sun, between 2.06 and 3.28AU, a region called themain belt. The mean distances are not uniformly distributed but exhibit...
[NASA's 17 Apollo Moon Missions in Pictures] A challenging mission Unmanned probes have successfully rendezvoused with asteroids in deep space multiple times. Japan's Hayabusa craft even snagged pieces of the near-Earth asteroid Itokawa in 2005, sending them back to our planet for study. But ...
astronomers has usedNASA’sJames Webb Space Telescopetodetect a very small asteroid. The asteroid – about 300 to 650 feet long – is likely the smallest object observed to date by Webb and may be an example of an object less than 0.6 miles long within the main asteroid belt betwee...

4. NASA tells us it would love to send a probe to catch up with 'Oumuamua, but its whopping delta-V of 60 km/s is beyond current tech using chemical propulsion. 5. We call these objects comets if they outgas visibly, though the line between asteroids and comets has always been blurry...
NASA has revealed more about its plans to visit thestrange metal asteroid Psyche, as part of a mission launching next year. Set to launch in August 2022, the Psyche spacecraft will travel to the strange metal asteroid also called Psyche, located in the asteroid belt between the orbits of Ma...
This illustration depicts the metal-rich asteroid Psyche, which is located in the main asteroid belt between Mars and Jupiter. Photo: NASA/JPL-Caltech/ASU More than just being cool, mining asteroids could be an important source of rare metals and a crucial part of our plan to undo ...
The space probeGalileo,which passed near and photographed Gaspra (1991) and Ida (1993), provided the first close images of an asteroid. The pictures revealed that Ida has a natural satellite, Dactyl. Ida, in the main asteroid belt between Mars and Jupiter, is about 35 mi (56 km) long ...
