The angular form of the edge of It found Mathilde to be composed of extremely dark material, with numerous large impact craters, including one nearly six miles deep. 253 Mathilde is seriously battered. In this image, the asteroid has been rotated so that the The NEAR then flew back to Earth for a gravity assist, one that put it on a trajectory for 433 Eros. data from an encounter. Vesta is so large it's like a small planet. The fictional asteroid is quoted as having a 70 mile diameter, somewhat larger than that of 253 Mathilde, which does not have an orbit that intersects Earth's (see above)." miles across) almost fully lit by the Sun at a phase angle of 43° (right image). It flew within 750 mi (1,200 km) of minor planet 253 Mathilde on June 27, 1997, and took spectacular images of the dark, crater-battered world. Most meteorites found on Earth are originally from the asteroid belt, some can even be traced back to the particular asteroid they came from. Ida is the first known asteroid that to be discovered that has a moon called Dactyl. In the case of Ida, its moon Dactyl (the dot of light on the right) orbits once every 37 hours at an average distance of 108 km (67 miles). The director says in interviews that she studied previous asteroid disaster films and stories, and the fictional asteroid has a name that sounds identical to the real Mathilde. These are views of the three asteroids that have been imaged at close range by spacecraft. Mathilde is also unique because it has an extremely long period of rotation. The size of asteroids varies from the size of a speck of dust to the size of 945 kilometers (587 miles) in diameter! A relatively small, at times active, object whose ices can vaporize in sunlight forming an atmosphere … This image mosaic of asteroid 253 Mathilde is constructed from four images acquired by the Near Earth Asteroid Rendezvous (NEAR) spacecraft on June 27, 1997. It became the first spacecraft to enter orbit around an asteroid, doing so at the large near-Earth asteroid 433 Eros in February 2000. The asteroid belt is a ring shaped area, located between the orbits of Mars and Jupiter that contains more than 5,000 asteroids. Large Impact Crater on Mathilde Even at that high speed, during the 25-minute encounter NEAR managed to capture more than 500 spectacular images of the crater-pocked little world. biggest asteroids-largest=Ceres, d~1000km (1/4 moon)-2nd largest: Vesta, d~500km.

Mathilde which resulted in more than 500 images of a dark, Interest in Mathilde was minimal until the NEAR flyby was announced in 1995. In fact, judging by its low density, Mathilde may be more of a loosely-packed pile of material than solid rock. Scientists were also concerned about possible dust particles Photograph taken in 1997 by the NEAR Shoemaker probe. (253) Mathilde Asteroid. encounter with Mathilde was frought with difficulty. In 2016, NASA launched the OSIRIS-REx spacecraft to study an asteroid near Earth named Bennu and bring a sample of the asteroid back to Earth!

It now appears such a thing is quite common. A few asteroids have asteroid moon. This is the dwarf planet Ceres – the largest discovered asteroid in the solar system. Thousands more are discovered each year. Without searching for these asteroid companions before launch, Lucy runs the risk of encountering an unexpected binary pair. It is named for the god of love in Greek mythology. Mathilde is a C-type asteroid, which means that it is made of rock rich in carbon, and is probably very little changed in the last 4.5 billion years, a time capsule from the time the planets first formed.

It's about 52 kilometers across, and notable for its very slow rotation rate--it takes 17.4 days for the asteroid to turn on its axis. The image at left was pieces off the asteroid. "Mathilde turned out to be more irregularly shaped than most of us expected," said Dr. Joseph Veverka of Cornell University, who lead the mission's imaging science team. NASA’s OSIRIS-REx completed its last flyover of Bennu on April 7 and is now slowly drifting away from the asteroid; NASA’s Lucy spacecraft has successfully completed thermal vacuum testing of both solar panels. Vesta is the second most massive body in the asteroid belt, surpassed only by Ceres, which is classified as a dwarf planet. A spacecraft racing past an asteroid millions of miles from Earth captured spectacular views, with clear images of a miles-deep crater punched into the battered, coal-black surface of a space rock named Mathilde.
