2011) oMany have elevated radar albedos, suggesting high surface density (e.g., Neeley et al. For small bodies that are not internally differentiated, the surface and internal compositions are presumably similar, while large bodies such as Ceres and Vesta are known to have internal structure. The rare O-type asteroids have spectra similar to the unusual asteroid 3628 Boznemcová, which is the best asteroid match to the spectra of L6 and LL6 ordinary chondrite meteorites.Their spectra have a deep absorption feature longward of 0.75 μm.. Generally similar to the C-type objects, but contain a strong ultraviolet absorption feature below 0.5 μm. P-type objects are distinguished from the spectrally similar E-type and M-type asteroids by their lower albedo (in the range 0.02 to 0.06). 2010, Hardersen et al. 2015) oMost have weak silicate features at 0.9 μm ±1.9 μm (e.g., Fornasier et al.
O-type asteroid Wikipedia open wikipedia design. List Box 78, 28691 Villanueva de la Canada,˜ Madrid, Spain Abstract The small bodies of our solar system are the remnants of the early stages of planetary formation. The rare O-type asteroids have spectra similar to the unusual asteroid 3628 Boznemcov á, which is the best asteroid match to the spectra of L6 and LL6 ordinary chondrite meteorites. Their spectra have a deep absorption feature longward of 0.75 μm. 2000, Landsman et al. The largest example is the 282-kilometer-wide 87 Sylvia. Carry European Space Astronomy Centre, ESA, P.O. Density of asteroids B. Characteristics. E-type asteroids have a high albedo (0.3 or higher), which distinguishes them from the more common M-type asteroids. The most notable asteroid in this class is 1 Ceres. List . Their spectrum is featureless flat to reddish. The M-Type Asteroids oM-types are the moderate-albedo group of the spectrally degenerate X taxon oMany have a 3-μm hydration feature (e.g., Rivkin et al. The largest example is the 282-kilometer-wide 87 Sylvia. An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo.These types are thought to correspond to an asteroid's surface composition. O-type-asteroidar er sjeldne asteroidar med like spektraltrekk til den uvanlege asteroiden 3628 Boznemcová, som har dei mest like spektraa til L6 og LL6 kondritt meteorittar.Spektraa deira har eit djupt absorpsjonstrekk ved lengre bølgjelengder enn 0,75 μm G-type asteroids are a relatively uncommon type of carbonaceous asteroid that makes up approximately 5% of asteroids.
