M-type asteroid

Index M-type asteroid

M-type asteroids are asteroids of partially known composition; they are moderately bright (albedo 0.1–0.2). [1]

Albedo

Albedo (albedo, meaning "whiteness") is the measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body (e.g. a planet like Earth).

Asteroid spectral types

An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo (reflectivity).

Bone

A bone is a rigid organ that constitutes part of the vertebrate skeleton.

C-type asteroid

C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids.

Iron meteorite

Iron meteorites are meteorites that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite.

Mineral hydration

Mineral hydration is an inorganic chemical reaction where water is added to the crystal structure of a mineral, usually creating a new mineral, usually called a hydrate.

Nickel

Nickel is a chemical element with symbol Ni and atomic number 28.

Puerto Rico

Puerto Rico (Spanish for "Rich Port"), officially the Commonwealth of Puerto Rico (Estado Libre Asociado de Puerto Rico, "Free Associated State of Puerto Rico") and briefly called Porto Rico, is an unincorporated territory of the United States located in the northeast Caribbean Sea.

Rosetta (spacecraft)

Rosetta was a space probe built by the European Space Agency launched on 2 March 2004.

Rubble pile

In astronomy, a rubble pile is a celestial body that is not a monolith, consisting instead of numerous pieces of rock that have coalesced under the influence of gravity.

S-type asteroid

S-type asteroids are asteroids with a spectral type that is indicative of a silicaceous (i.e. stony) mineralogical composition, hence the name.

Silicate

In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula, where 0 ≤ x Silicate anions are often large polymeric molecules with an extense variety of structures, including chains and rings (as in polymeric metasilicate), double chains (as in, and sheets (as in. In geology and astronomy, the term silicate is used to mean silicate minerals, ionic solids with silicate anions; as well as rock types that consist predominantly of such minerals. In that context, the term also includes the non-ionic compound silicon dioxide (silica, quartz), which would correspond to x.
