This glossary is made for amateurs to help understand the whole wiki or solar system. after the 'main' glossary comes an glossary that define term of everything outside the solar system.

Terms used in the solar systemEdit

(These terms could also be used outside the solar system but are also used in the solar system so, they are adopted).

AEdit

Mars

On Mars, there is an big difference of albedo, but for example,on Uranus, it's not.

  • Achondrite - is a meteorite consisting of igneous minerals and no chondrules, very similar to terrestrial igneous rocks[1][2]
  • Albedo - is the ratio of the amount of light reflected from a surface to the amount of incident light[3]
  • Aperture - is the effective diameter of the primary mirror or lens of a telescope.[4]
  • Aphelion - is the point in a planetary orbit that is at the greatest distance from the Sun.[5]
  • Apparent Magnitude - is the brightness of a star as it appears to the eye or to the telescope, as measured in units of magnitude—the brighter the star, the smaller the apparent magnitude.[6]
  • Asteroid - (also called a “minor planet”)is a small solar system object in orbit around the sun composed mostly of rock. Many of these objects orbit the sun between Mars and Jupiter. Their size can range anywhere from 100 meters in diameter to almost 1000 kilometers. Principal asteroids – Ceres, Pallas, Juno and Vesta C-type asteroids are carbon-rich, very dark, reflect on 3%-9% of sunlight. S-type asteroids are comprised of metallic nickel-iron mixed with iron- and magnesium-silicates. V-type asteroids contain more pyroxene than S-type asteroids.[7]
  • Asteroid belt - is a region of space lying between Mars (1.5 AU) and Jupiter (5.2 AU), where the great majority of the asteroids are found.[8]
  • Astronomical Unit - is the mean distance between the Earth and the Sun: 149,598,500km; the preferred unit for distances within the Solar System.[9]
  • Axis of rotation - is the theoretical straight line through a celestial body, around which it rotates.[10]

BEdit

  • Bode’s Law - is a law that describes a mathematical method for calculating planetary distances which states that the distance to the nth planet is 0.4 + (0.3)n Astronomical Units. Bodes law works surprisingly well out to Uranus.

CEdit

  • Ceres-accounts nearly 1/3 of the total mass of the Asteroid belt.

Please read the following carefully!

  • In this article, it is NOT forbidden to copy terms from other site's, because a term is defined.
  • every term on this article must be referred to an Dictionary site.
  • Please follow the lay-out as it was before, hold this structure.
  • Aslo planets may be adopted, BUT only inside 'our' solar system
