Suspected satellites are marked as <code>[unconfirmed]</code> in the “Satellite Notes” column. Publicly available orbital and physical properties of the satellites can be displayed in the table below by selecting the appropriate checkbox. Additional information might be available in the object page that can be reached by clicking on the object name.</p> <p>Satellites of small-bodies are mainly discovered through radar observations (e.g., Margot et al. 2002, Science 296), lightcurve observations (e.g., Pravec et al. 2006, Icarus 181), and direct optical imaging (e.g., Brown and Margot 2001, IAUC 7588). The method of discovery for each satellite is described in the source listed in the “Satellite Reference” column. Most small-bodies with known satellites are binary systems, i.e, they have a single known satellite, but some systems have two or more satellites.</p> <h2>Table of Asteroids with Satellites</h2> <div ng-app="sbSats" ng-controller="sbSatsCtrl"> <div class="panel panel-info panel-compact"> <div class="panel-heading">Optionally, include one or both of the following additional field groups in the table:</div> <div class="panel-body"> <ul class="list-unstyled no-bottom-margin"> <li class=""> <div extra-fields-checkbox label="show orbital parameters" model="show.elem" update="updateTable()" tip="displays the following orbital elements: e, a, per, and a/D (with reference and notes)"></div> </li> <li class=""> <div extra-fields-checkbox label="show physical parameters" model="show.phys" update="updateTable()" tip="displays the following physical parameters: diameter, extent, roation period, GM, and bulk density"></div> </li> </ul> </div> </div> <form> <div class="form-group"> <label>Show:</label> <select ng-model="confirmed" ng-change="filterByConfirmed()"> <option value="all">all satellites</option> <option value="Y">only confirmed satellites</option> <option value="N">only unconfirmed satellites</option> </select> </div> </form> <table id="sb_sats" class="table table-sb-sats table-bordered table-striped table-hover table-condensed"> <thead> <tr> <th rowspan="2">id</th> <th rowspan="2">pdes</th> <th rowspan="2" class="text-nowrap">Primary Body<br/>Designation</th> <th rowspan="2" class="text-nowrap">Primary Body<br/>Orbit Class</th> <th rowspan="2" class="text-nowrap" label="<br/>Satellite" ssd-th-tip="satellite designation"></th> <th rowspan="2" class="text-nowrap">Discovery<br/>Year</th> <th rowspan="2" class="text-nowrap">Satellite<br/>Reference</th> <th rowspan="2" class="text-nowrap">Satellite<br/>Notes</th> <th rowspan="2">oid</th> <th rowspan="2" class="text-nowrap" label="e" units="none" ssd-th-tip="eccentricity"></th> <th rowspan="2" class="text-nowrap" label="a" units="km" ssd-th-tip="semimajor axis"></th> <th rowspan="2" class="text-nowrap" label="per" units="h" ssd-th-tip="orbital period"></th> <th rowspan="2" class="text-nowrap" label="a/D" units="none" ssd-th-tip="ratio of the satellite's semimajor axis to the primary body diameter"></th> <th rowspan="2" class="text-nowrap" label="Orbit<br/>Reference" units="none" ssd-th-tip="reference for orbital parameters"></th> <th rowspan="2" class="text-nowrap" label="Orbit<br/>Notes" units="none" ssd-th-tip="notes for orbital parameters"></th> <th colspan="3" class="text-nowrap text-center" label="diameter" ssd-th-tip="effective satellite diameter"></th> <th colspan="3" class="text-nowrap text-center" label="extent" ssd-th-tip="tri(or bi)-axial satellite dimensions"></th> <th colspan="3" class="text-nowrap text-center">rotation period</th> <th colspan="3" class="text-nowrap text-center" label="GM" ssd-th-tip="standard gravitational parameter: product of the mass (M) and gravitational constant (G)"></th> <th colspan="3" class="text-nowrap text-center">bulk density</th> </tr> <tr> <th class="text-nowrap">value<br/>(km)</th> <th class="text-nowrap">ref.<br/> </th> <th class="text-nowrap">notes<br/> </th> <th class="text-nowrap">value<br/>(km)</th> <th class="text-nowrap">ref.<br/> </th> <th class="text-nowrap">notes<br/> </th> <th class="text-nowrap">value<br/>(h)</th> <th class="text-nowrap">ref.<br/> </th> <th class="text-nowrap">notes<br/> </th> <th class="text-nowrap">value<br/>km<sup>3</sup>/s<sup>2</sup></th> <th class="text-nowrap">ref.<br/> </th> <th class="text-nowrap">notes<br/> </th> <th class="text-nowrap">value<br/>g/cm<sup>3</sup></th> <th class="text-nowrap">ref.<br/> </th> <th class="text-nowrap">notes<br/> </th> </tr> </thead> </table> </div>  <div id="footer" class="container-fluid footer"> <div class="row"> <div class="col-sm-5 col-xs-12"> <img class="ssd-logo" src="/images/ssd_logo.png" alt="SSD Logo" /> </div> <div class="col-sm-3 col-xs-12"> <div class="link-inv"> <a href="/sitemap.html"><i class="fa-fw fa fa-list-alt"></i> Site Map</a> </div> <div class="link-inv"> <a href="https://www.jpl.nasa.gov/caltechjpl-privacy-policies-and-important-notices"><i class="fa-fw fa fa-user-secret"></i> Privacy</a> </div> <div class="link-inv"> <a href="https://www.jpl.nasa.gov/jpl-image-use-policy"><i class="fa-fw fa fa-picture-o"></i> Image Policy</a> </div> </div> <div class="col-sm-4 col-xs-12"> <div class=" link-inv"> <a href="/contact/"><i class="fa-fw fa fa-envelope"></i> Contact Us</a> </div> <div class="text-smaller"> <span class="footer-label text-nowrap">Site Manager:</span> <span class="text-nowrap">Ryan Park</span> </div> <div class="text-smaller2"> <span class="footer-label text-nowrap">Site Design:</span> <span class="text-nowrap">Alan B.
