Albedo

Albedo is the fraction of sunlight that is diffusely reflected by a body.

See P-type asteroid and Albedo

Anhydrous

A substance is anhydrous if it contains no water.

See P-type asteroid and Anhydrous

Asteroid

An asteroid is a minor planet—an object that is neither a true planet nor an identified comet— that orbits within the inner Solar System.

See P-type asteroid and Asteroid

Asteroid belt

The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars.

See P-type asteroid and Asteroid belt

Asteroid spectral types

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. P-type asteroid and asteroid spectral types are asteroid spectral classes.

See P-type asteroid and Asteroid spectral types

Astronomical unit

The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.

See P-type asteroid and Astronomical unit

C-type asteroid

C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids. P-type asteroid and c-type asteroid are asteroid spectral classes.

See P-type asteroid and C-type asteroid

Cambridge University Press

Cambridge University Press is the university press of the University of Cambridge.

See P-type asteroid and Cambridge University Press

Carbon

Carbon is a chemical element; it has symbol C and atomic number 6.

See P-type asteroid and Carbon

Carbonaceous chondrite

Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites.

David J. Tholen

David James Tholen (born 1955) is an American astronomer at the Institute for Astronomy of the University of Hawaiʻi.

Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice.

See P-type asteroid and Ice

Kerogen

Kerogen is solid, insoluble organic matter in sedimentary rocks.

See P-type asteroid and Kerogen

M-type asteroid

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 other asteroid classes, and are widely thought to be the source of iron meteorites. P-type asteroid and m-type asteroid are asteroid spectral classes.

See P-type asteroid and M-type asteroid

S-type asteroid

S-type asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name. P-type asteroid and s-type asteroid are asteroid spectral classes.

See P-type asteroid and S-type asteroid

Silicate

A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula, where.

See P-type asteroid and Silicate

Solar System

The Solar SystemCapitalization of the name varies.

See P-type asteroid and Solar System

Space weathering

Space weathering is the type of weathering that occurs to any object exposed to the harsh environment of outer space.

See P-type asteroid and Space weathering

Sun

The Sun is the star at the center of the Solar System.

Tagish Lake (meteorite)

The Tagish Lake meteorite fell at 16:43 UTC on 18 January 2000 in the Tagish Lake area in northwestern British Columbia, Canada.

See P-type asteroid and Tagish Lake (meteorite)

Thesis

A thesis (theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.

476 Hedwig

Hedwig (minor planet designation: 476 Hedwig) (1901 GQ) is a main-belt asteroid discovered on August 17, 1901, by Luigi Carnera at Heidelberg. P-type asteroid and 476 Hedwig are p-type asteroids (Tholen).
