For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
The list of minor planets consists of more than 700 partial lists, each containing 1000 minor planets grouped into 10 tables. The data is sourced from the Minor Planet Center (MPC) and expanded with data from the JPL SBDB (mean-diameter), Johnston's archive (sub-classification) and others (see detailed field descriptions below).
This is a list of the lists of small Solar System bodies and dwarf planets. Lists of comets; List of minor planets; List of named minor planets (alphabetical) List of named minor planets (numerical) List of exceptional asteroids; List of trans-Neptunian objects; List of fast rotators (minor planets) List of slow rotators (minor planets)
The following is a partial list of minor planets, running from minor-planet number 10001 through 11000, inclusive.The primary data for this and other partial lists is based on JPL's "Small-Body Orbital Elements" [1] and data available from the Minor Planet Center.
Stargazers who have heard of an amazing planetary alignment coming later in January may be in for a letdown if they look up at the night sky expecting to be dazzled.. Yes, six planets will be ...
Flyby; discovered Selam; smallest main-belt asteroid to be visited by a spacecraft [9] [10] Notes: a A minor planet's dimensions may be described by x, y, and z axes instead of an (average) diameter due to its non-spherical, irregular shape. b Closest approach given in multiples of the minor planet's mean radius
This is a list of named minor planets in an alphabetical, case-insensitive order grouped by the first letter of their name. [a] [b] New namings, typically proposed by the discoverer and approved by the Working Group for Small Bodies Nomenclature (WGSBN) of the International Astronomical Union, are published nowadays in their WGSBN Bulletin and summarized in a dedicated list several times a year.
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun.Most named objects in this list have a diameter of 500 km or more.
