How are objects like asteroids, comets, and satellites named and what organization oversees this nomenclature? Give some examples. How are features on hard planetary surfaces named and what are some of the themes used on different planetary bodies? How does the two-part nomenclature work? Give some specific examples from one or more planetary surfaces we discussed or that you read about. 2. Describe the different kinds of planetary and satellite maps. Regarding geological mapping of planets and satellites, what is a geological unit? Explain the three-fold system of geological classification used on planetary and satellite maps. What are the main geological system names on the Moon and Mars? (List these in order for both the Moon and Mars.) Describe the system of lettering that is used on planetary (and satellite) geological maps and explain the rationale of the lettering system. Give some examples. 3. Describe the nature and use of the principle of crater gradation in correlation. How is crater counting used in determining the age of planetary surfaces? What other ways do we have of determining the age of planetary surfaces? In other words, how can we apply relative age-dating principles from Earth to other planets? (Think about the basic geological principles given at the outset of the e-textbook.) What is a T-junction on a geological map and what can it tell you about relative age? 08:40 AM O Type here to search 9/10/2018 3Explanation / Answer
Answer : 1 : How are they named ?
In recent years, the comet-naming process has been impacted by several wide-field CCD surveys conducted by professional teams. It is therefore appropriate to write down guidelines for the naming of comets to make the process as simple and fair as possible. Though guidelines have been drafted previously by IAU Commission 20 members in recent years, this aims to replace those guidelines by starting anew, by creating guidelines that are even simpler and more fair. These guidelines may need to be revised by the WGSBN, as special circumstances warrant. The MPC receives astrometry, makes identifications and computes comet orbits, and makes collections of observations and orbits available to the community. In recent practice, comet names are announced on Minor Planet Electronic Circulars after a reasonable orbit has been determined, in an effort to prevent re-naming of lost comets. The MPC consults with the WGSBN on non-routine naming matters, in which some interpretation of the following guidelines is deemed appropriate.
