3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

... Satellites of the planets are assigned a provisional designation (indicating year of discovery) by the Central Bureau for Astronomical Telegrams ( CBAT ) upon satisfactory demonstration of the existence of a new object. ... In the past, Comets were first given a provisional designation, consisting of the year and a lowercase letter indicating the order of discovery in the year (e.g., 1994a was the first comet discovered or recovered in 1994, 1994b the second, etc.) ...

This section of AMPLE enables one to make ephemeris calculations in various coordinate systems (spherical, rectangular) connected with different main planes (equator, ecliptic, horizon) and having origin in different points: geocenter, any point on the Earth surface, the Sun, any major planet, any minor planet. The choice of some minor planet as a center gives possibility to find approaches of the minor planet with any set of major planets and minor planets. ... equinox . 1950 2000 true . ...

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. ...
