It has a fairly elliptical orbit that takes more than four years to circle the Sun.This asteroid has an unusually slow rate of rotation, taking 17.4 days to complete a 360° revolution about its axis.

The asteroid rotates very slowly, once every 418 hours (about 17.5 days). Diameter: km: Massa: kg: Densitas media: g/cm 3: Periodus rotationis: 417 h 42.000732 m: Classis spectralis. On 27 June 1997, the Near Earth Asteroid Rendezvous (NEAR) spacecraft flew within 1212 kilometers of asteroid 253 Mathilde. 253 Mathilde eller 1949 OL 1 är en asteroid upptäckt av Johann Palisa 1885 i Wien [1], som senare fick namnet Mathilde, förmodligen efter astronomen Moritz Loewys hustru. On its way to Eros, NEAR Shoemaker paid a brief visit to asteroid (253) Mathilde in June 1997. A major difference between Ida and Mathilde appears to be the abundance of very large craters: Mathilde has at least 5 craters larger than 20 km in diameter on the roughly 60% of the body viewed during the encounter.

Mathilde's density is only 1.4 gm/cm 3. Astronomers measuring the reflected light have classified 253 Mathilde as a C type asteroid, thought to be similar to carbonaceous chondrites. It has a elliptical orbit that requires more than four years to circle the Sun; this tumbling asteroid has an unusually slow rate of rotation, requiring 17.4 days to complete a 360° revolution about its axis. 253 Mathilde is a main belt asteroid found by Johann Palisa in 1885. Orbital Elements at Epoch 2459000.5 (2020-May-31.0) TDB Reference: JPL 212 (heliocentric ecliptic J2000) Ida and Gaspra do not have such large craters. [4]. 253 Mathilde (Or Jupiter IIIXXXX) is an moon Of Jupiter in the Gossamer Ring Of Jupiter. For details see the article NEAR's Flyby of 253 Mathilde: Images of a C Asteroid which appeared in Science Magazine 19 December 1997 and the NEAR Home Page. On ∼53 km diameter 253 Mathilde it is The name is thought to honor the wife of astronomer Moritz Loewy, then the vice director of the Paris Observatory. However, uncertainties in our knowledge of collisional physics of large bodies and the number of small asteroids could allow an age as young as 2 billion years. 253 Mathilde (Or Jupiter IIIXXXX) is an moon Of Jupiter in the Gossamer Ring Of Jupiter. ... Mathilde has at least 5 craters larger than 20 km in diameter on the roughly 60% of the body viewed during the encounter. It is approximately 50 x 50 x 70 km in size. Asteroid 253 Mathilde is found to have a collisional lifetime of approximately 4 billion years, essentially indistinguishable from the age of the Solar System. The diameter DL of the largest undegraded crater is by definition not ambiguous, and is adopted as the basis for this model. Technically referred to as 253, Mathilde is a main-belt asteroid about 50 km in diameter. Den har en relativt elliptisk omloppsbana som har en omloppstid på mer än fyra år runt Solen.Denna asteroid har en ovanligt långsam rotation, det tar asteroiden 17,4 dagar att fullborda ett varv runt sin egen axel.

approximately 50 kilometers in diameter, that was discovered by Austrian astronomer Johann Palisa at Vienna Observatory on 12 November 1885. So, Wilson and colleagues assume 253 Mathilde is a carbonaceous chondrite, with a porosity of about 15 to 35% (see table above). 253 Mathilde /məˈtɪldə/ is a main-belt asteroid about 50 km in diameter that was discovered by Johann Palisa in 1885. Reflecting only 3.6% of the light incident on it, Mathilde is one of the darkest objects in the solar system. 253 Mathilde Mathilde is an asteroid in the intermediate asteroid belt 50 kilometers in diameter, discovered by Austrian astronomer Johann Palisa at Vienna Observatory on 12 November 1885. It has a fairly elliptical orbit that takes more than four years to circle the Sun.This asteroid has an unusually slow rate of rotation, taking 17.4 days to complete a 360° revolution about its axis. It has a fairly elliptical orbit that takes more than four years to circle the Sun.This asteroid has an unusually slow rate of rotation, taking 17.4 days to complete a 360° revolution about its axis. The asteroid's surface is dark (estimated albedo between 0.035 and 0.050) and similar in color to some CM carbonaceous chondrites. It has a relatively elliptical orbit that requires more than four years to circle the Sun. Abundance of Very Large Impact Craters on Mathilde This view of 253 Mathilde, taken from a distance of about 1,200 km (748 miles), was acquired shortly after the NEAR spacecraft's closest approach to the asteroid.

If one debates whether or no t it is a crater, then it is not DL. The piece can slide either up or down to hang the spheres low or high. Beautifully balanced, the Mathilde necklace features a 1″ concrete sphere suspended below a smaller stainless ball.
