Planetary science

Cosmochemistry (from Greek κόσμος kósmos, "universe" and χημεία khemeía) or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions.

Planetary nomenclature, like terrestrial nomenclature, is a system of uniquely identifying features on the surface of a planet or natural satellite so that the features can be easily located, described, and discussed.

A magnetosphere is the region of space surrounding an astronomical object in which charged particles are controlled by that object's magnetic field.

The magnetosphere of Jupiter is the cavity created in the solar wind by the planet's magnetic field.

A bolide (French via Latin from the Greek βολίς bolís, "missile") is an extremely bright meteor, especially one that explodes in the atmosphere.

Tektites (from Greek τηκτός tēktós, "molten") are gravel-size bodies composed of black, green, brown or gray natural glass formed from terrestrial debris ejected during meteorite impacts.

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

The scattered disc (or scattered disk) is a distant circumstellar disc in the Solar System that is sparsely populated by icy minor planets, a subset of the broader family of trans-Neptunian objects.

The definition of planet, since the word was coined by the ancient Greeks, has included within its scope a wide range of celestial bodies.

the Foucault pendulum (English pronunciation: /fuːˈkoʊ/ foo-KOH; French pronunciation: ​[fuˈko]), or Foucault's pendulum, named after the French physicist Léon Foucault, is a simple device conceived as an experiment to demonstrate the rotation of the Earth.

An accretion disk is a structure (often a circumstellar disk) formed by diffused material in orbital motion around a massive central body.

Selenography is the study of the surface and physical features of the Moon.

A gravity anomaly is the difference between the observed acceleration of a planet's reaction to gravity and a value predicted from a model.

The formation of the Solar System began 4.

In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System.

The Kuiper belt /ˈkaɪpər/ or Dutch pronunciation: ['kœy̯pǝr], sometimes called the Edgeworth–Kuiper belt, is a circumstellar disc in the Solar System beyond the planets, extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun.

A micrometeoroid is a tiny meteoroid; a small particle of rock in space, usually weighing less than a gram.

Comparative planetary science or comparative planetology is a branch of space science and planetary science in which different natural processes and systems are studied by their effects and phenomena on and between multiple bodies.

A satellite system is a set of gravitationally bound objects in orbit around a planetary mass object or minor planet.

NASA Regional Planetary Image Facilities (RPIFs) are planetary image and data libraries located throughout the United States and abroad that are funded by both NASA and the host institutions.

A quake is the result when the surface of a planet, moon or star begins to shake, usually as the consequence of a sudden release of energy transmitted as seismic waves, and potentially with great violence.

The British and Irish Meteorite Society (BIMS) is a group of 150+ Meteorite researchers and amateurs.

Icarus is a scientific journal dedicated to the field of planetary science.

Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because almost no one knew or believed that the Solar System, in the sense we now understand it, existed.

Earth radius is the distance from the Earth's center to its surface, about 6,371 km (3,959 mi).

The Meteoritical Society is a non-profit scholarly organization founded in 1933 to promote research and education in planetary science with emphasis on studies of meteorites and other extraterrestrial materials that further our understanding of the origin and history of the solar system.

An aurora, sometimes referred to as a polar light, is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.
