B-type asteroids are a relatively uncommon type of carbonaceous asteroid, falling into the wider C-group; the 'B' indicates these objects are spectrally...

C-type (carbonaceous /ˌkɑːrbəˈneɪʃəs/) asteroids are the most common variety, forming around 75% of known asteroids. They are volatile-rich and distinguished...

E-type asteroids are asteroids thought to have enstatite (MgSiO3) achondrite surfaces. They form a large proportion of asteroids inward of the asteroid...

F-type asteroids are a relatively uncommon type of carbonaceous asteroid, falling into the wider C-group. F-type asteroids have spectra generally similar...

M-type (aka M-class) asteroids are a spectral class of asteroids which appear to contain higher concentrations of metal phases (e.g. iron-nickel) than...

silicates, possibly with water ice in their interiors. D-type asteroids are found in the outer asteroid belt and beyond; examples are 152 Atala, 944 Hidalgo...

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. These types are thought to correspond...

B type or Type B may refer to: B-type asteroid, a type of relatively uncommon type of carbonaceous asteroid B-type giant, a type of blue giant star B-type...

considered to be a planet, as were other asteroids in the early 19th century. The discovery of many more asteroids after 1845 eventually led to the separate...

active Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid (though there are numerous unnamed asteroids with smaller...

class it as type B. Elpis was discovered by Jean Chacornac from Paris, on September 12, 1860. It was Chacornac's sixth and final asteroid discovery. A...

Main belt asteroid. It is classified as a B-type asteroid and probably has a primitive composition not unlike common C-type carbonaceous asteroids. It was...

372 Palma is one of the largest main-belt asteroids. It is a B-type asteroid. It was discovered by Auguste Charlois on August 19, 1893, in Nice. It is...

as the main asteroid belt. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly...

Bennu, Phaethon, and inactive Manx comets are examples of active asteroids. B-type asteroids displaying a blue color in particular, may be dormant comets...

near-infrared spectrum of Chiron is neutral, and is similar to that of C-type asteroids and the nucleus of Halley's Comet. The near-infrared spectrum of Chiron...

It is the largest and most massive of the M-type asteroids, and one of the dozen most massive asteroids. It has a mean diameter of approximately 220...

Interamnia is the largest asteroid after the "big four", it is a very little-studied body. It is easily the largest of the F-type asteroids, but until 2017-2019...
