Minor Planet - Physical Properties of Comets and Minor Planets

Physical Properties of Comets and Minor Planets

Commission 15 of the International Astronomical Union is dedicated to the Physical Study of Comets & Minor Planets.

Archival data on the physical properties of comets and minor planets are found in the PDS Asteroid/Dust Archive. This includes standard asteroid physical characteristics such as the properties of binary systems, occultation timings and diameters, masses, densities, rotation periods, surface temperatures, albedoes, spin vectors, taxonomy, and absolute magnitudes and slopes. In addition, European Asteroid Research Node (E.A.R.N.), an association of asteroid research groups, maintains a Data Base of Physical and Dynamical Properties of Near Earth Asteroids.

Most detailed information is available from Category: Asteroids visited by spacecraft and Category: Comets visited by spacecraft.

Famous quotes containing the words physical, properties, comets, minor and/or planets:

    When one walks, one is brought into touch first of all with the essential relations between one’s physical powers and the character of the country; one is compelled to see it as its natives do. Then every man one meets is an individual. One is no longer regarded by the whole population as an unapproachable and uninteresting animal to be cheated and robbed.
    Aleister Crowley (1875–1947)

    The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.
    John Locke (1632–1704)

    I know
    No answer to the children’s cry
    Of echo’s answer and the man of frost
    And ghostly comets over the raised fists.
    Dylan Thomas (1914–1953)

    Great causes are never tried on their merits; but the cause is reduced to particulars to suit the size of the partizans, and the contention is ever hottest on minor matters.
    Ralph Waldo Emerson (1803–1882)

    I would sell my life to avoid
    the pain that begins in the crib
    with its bars or perhaps
    with your first breath
    when the planets drill
    your future into you....
    Anne Sexton (1928–1974)
