- In Depth | Asteroids – NASA Solar System Exploration
The current known asteroid count is: Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across
- In Depth | Kuiper Belt – NASA Solar System Exploration
The Kuiper Belt is a large region in the cold, outer reaches of our solar system beyond the orbit of Neptune It's sometimes called the "third zone" of the solar system Astronomers think there are millions of small, icy objects in this region – including hundreds of thousands that are larger than 60 miles (100 kilometers) wide Some of the objects, including Pluto, are over 600 miles (1,000
- Psyche Raw Images – NASA Solar System Exploration
Psyche Raw Images On May 15, 2026, NASA's Psyche mission flew past Mars for a gravity assist This maneuver gave the spacecraft a boost to its ultimate destination, the asteroid Psyche, which it will explore in 2029 The images taken before, during, and after the Mars flyby will appear here and will initially show mostly star fields, but the planet will grow in size as the spacecraft
- Make Your Own Awesome Asteroid - NASA Solar System Exploration
Activity Instructions • Each person selects clay as desired and adds “silicates” (rocks and or sand) to make an awesome, one-of-a-kind asteroid • For a rubble pile asteroid gently combine different clay and rocks to form a loose conglomeration of materials Leave some space between the fragments
- Kuiper Belt and Oort Cloud - NASA Solar System Exploration
The Kuiper Belt should not be confused with the Oort Cloud, which is a thousand times more distant In 1950, astronomer Jan Oort proposed that certain comets come from a vast, extremely distant spherical shell of icy bodies surrounding the solar system This giant swarm of objects, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units No objects
- In Depth | Phobos – NASA Solar System Exploration
Phobos has no atmosphere It may be a captured asteroid, but some scientists show evidence that contradicts this theory How Phobos Got its Name Hall named Mars' moons for the mythological sons of Ares, the Greek counterpart of the Roman god, Mars Phobos, whose name means fear is the brother of Deimos
- In Depth | Kore – NASA Solar System Exploration
The bulk of the original asteroid survived as the moon called Pasiphae, and the other pieces became some or all of the other moons in the group All of the Pasiphae moons are retrograde, so they orbit Jupiter in the opposite direction from the planet's rotation
- In Depth | Pasiphae – NASA Solar System Exploration
Pasiphae was probably an asteroid that was captured by Jupiter's gravity and then suffered a collision which broke off a number of pieces Those pieces became at least some, and perhaps all, of the other moons commonly categorized as members of the Pasiphae group
