Flashcards: Solar System

Heliocentrism, or heliocentricism, is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System.

The heliosphere is the bubble-like region of space dominated by the Sun, which extends far beyond the orbit of Pluto.

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.

Zodiacal light is a faint, roughly triangular, diffuse white glow seen in the night sky that appears to extend up from the vicinity of the Sun along the ecliptic or zodiac.

The stability of the Solar System is a subject of much inquiry in astronomy.

Tyche (/ˈtaɪki/) is a hypothetical gas giant located in the Solar System's Oort cloud, first proposed in 1999 by astrophysicists John Matese, Patrick Whitman and Daniel Whitmire of the University of Louisiana at Lafayette.

The formation of the Solar System began 4.

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

Following are the largest impact craters on various worlds of the Solar System.

Nemesis is a hypothetical red dwarf or brown dwarf, originally postulated in 1984 to be orbiting the Sun at a distance of about 95,000 AU (1.5 light-years), somewhat beyond the Oort cloud, to explain a perceived cycle of mass extinctions in the geological record, which seem to occur more often at intervals of 26 million years.

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.

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun.

The solar irradiance integrated over time is called solar irradiation, solar exposure or insolation.

Panguite is a type of titanium oxide mineral first discovered as an inclusion within the Allende meteorite, and first described in 2012.
