Achondrite

An achondrite is a stony meteorite that does not contain chondrules.

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

Asteroids are minor planets, especially those of the inner Solar System.

Asteroid belt

The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.

Asteroid spectral types

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

Aubrite

Aubrites are a group of meteorites named for Aubres, a small achondrite meteorite that fell near Nyons, France, in 1836.

E-belt asteroids

The E-belt asteroids were the population of a hypothetical extension of the primordial asteroid belt proposed as the source of most of the basin-forming lunar impacts during the Late Heavy Bombardment.

Electromagnetic spectrum

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.

Enstatite

Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO3) - ferrosilite (FeSiO3).

Feldspar

Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.

Forsterite

Forsterite (Mg2SiO4; commonly abbreviated as Fo) is the magnesium-rich end-member of the olivine solid solution series.

Gas giant

A gas giant is a giant planet composed mainly of hydrogen and helium.

Hungaria asteroid

The Hungaria group is a dynamical group of asteroids in the asteroid belt.

L-type asteroid

L-type asteroids are relatively uncommon asteroids with a strongly reddish spectrum shortwards of 0.75 μm, and a featureless flat spectrum longwards of this.

New!!: E-type asteroid and L-type asteroid · See more »

Late Heavy Bombardment

The Late Heavy Bombardment (abbreviated LHB and also known as the lunar cataclysm) is an event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, at a time corresponding to the Neohadean and Eoarchean eras on Earth.

M-type asteroid

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

Nice model

The Nice model is a scenario for the dynamical evolution of the Solar System.

Planetary migration

Planetary migration occurs when a planet or other stellar satellite interacts with a disk of gas or planetesimals, resulting in the alteration of the satellite's orbital parameters, especially its semi-major axis.

Rosetta (spacecraft)

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

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.
