Apart conventional orbital elements AMPLE gives possibility to calculate for each minor planet the following often used functions: . ... MOID . ... To calculate MOID user should order the name or the number of the major or minor planet through dialog. ... To calculate CT user should order the name or the number of the major or minor planet through dialog as it is proposed for MOID calculation. ...

Astropark Home . Solar System . ... Planets . ... A year is the time that it takes for a planet to go around the Sun. ... As a result, an Earth year is very different in length from a year on Saturn or any other planet. ... But on this scale, most of the planets are too small to see, so their size has been increased by 200 times. ... The Astropark's red gravel represents the asteroid belt – thousands of smaller bodies which range in size from pebbles up to small planets hundreds of miles across. ...

... Content Model: %Body.Content . ... Note that the ID, LANG and CLASS attributes can be used with virtually all of the elements permitted in the document body. ... CLASS . ... The CLASS attribute is most commonly used to attach a different style to some element, but it is recommended that where practical class names should be picked on the basis of the element's semantics, as this will permit other uses, such as restricting search through documents by matching on element class names. ...

. An illustration of the orbital distances and relative sizes of the four innermost planets known to orbit the star 55 Cancri A (bottom) in comparison with planets in own inner solar system (top). Both Jupiter and the Jupiter-mass planet 55 Cancri "d" are outside this picture, orbiting their host star with a distance of nearly 5 astronomical units (AU), where one AU is equal to the average distance between Earth and the Sun.

... Abstract Determine the set of osculating conic orbital elements that corresponds to the state (position, velocity) of a body at some epoch. ... In general, the elements found by this routine can have two kinds of problems: - The elements are not accurate but still represent the input state accurately. ... One recommended "sanity check" on the outputs is to supply them to the CSPICE routine conics_c and compare the resulting state vector with the one supplied to this routine. ...

Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ... Raw versions of real-time processing pictures FDS 0000984 and FDS 0000986 were used (images 196 and 202). ...
