LowEarthOrbit Low Earth Orbit Satellites in <a href="http://sw.opencyc.org/concept/Mx4ry7uFyHS_EdaAAACgyZzFrg" class="cyc_term">LowEarthOrbit</a> (LEO) have a period of about 90 minutes, because they must travel at a speed of about 17,000 miles per hour so that they will avoid the downward vector of the Earth's gravitational pull. Satellites in <a href="http://sw.opencyc.org/concept/Mx4ry7uFyHS_EdaAAACgyZzFrg" class="cyc_term">LowEarthOrbit</a> circle the Earth with an altitude of 200 - 500 miles.

Low Earth orbit

SpatiallyDisjointObjectType type of object whose instances do not physically overlap A collection of collections and a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is a collection C of spatial things (see <a href="http://sw.opencyc.org/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a>), where each of the spatial things in C is spatially disjoint with the other spatial things in C. For example, the collection <a href="http://sw.opencyc.org/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA" class="cyc_term">Dog</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a>, since dogs do not spatially overlap. Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups. Other instances of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> include <a href="http://sw.opencyc.org/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA" class="cyc_term">LatitudeLine</a>, <a href="http://sw.opencyc.org/concept/Mx4rvW4n1pwpEbGdrcN5Y29ycA" class="cyc_term">CompactDisc_Audio</a>, and <a href="http://sw.opencyc.org/concept/Mx4rwR7UWZwpEbGdrcN5Y29ycA" class="cyc_term">PlanetaryBody</a>. An important specialization of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is <a href="http://sw.opencyc.org/concept/Mx4rvVjlE5wpEbGdrcN5Y29ycA" class="cyc_term">SpatiallyDisjointRegionType</a> (a collection of specializations of <a href="http://sw.opencyc.org/concept/Mx4rvViACZwpEbGdrcN5Y29ycA" class="cyc_term">GeographicalRegion</a>, such as <a href="http://sw.opencyc.org/concept/Mx4rvVjnZ5wpEbGdrcN5Y29ycA" class="cyc_term">City</a> and <a href="http://sw.opencyc.org/concept/Mx4rwT-n15wpEbGdrcN5Y29ycA" class="cyc_term">TrueContinent</a>). A collection of collections. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> (q.v.). Moreover, each instance of <a href="http://sw.opencyc.org/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a collection that is temporally stuff-like (see <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>) but physically-spatially object-like (see <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>) -- i.e. object-like with respect to some physical-spatial part-whole predicate (e.g. some specialization of <a href="http://sw.opencyc.org/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>). Consider the collection <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a>. <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a>. Further, <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is temporally stuff-like: any one of the <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of a given copy <code>COPY</code> of (say) "Moby Dick" is still a copy of "Moby Dick". (Most collections of tangible objects are temporally stuff-like in this way.) But <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is spatially object-like: if we take a scalpel and slice <code>COPY</code> into ten pieces, each piece is not a copy of "Moby Dick". So <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a>. See also <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>. ExistingObjectType type of object A subcollection of <a href="http://sw.opencyc.org/concept/Mx4ro3lluGJHQdiVxrZReHS-jQ" class="cyc_term">EnduringThing_Localized</a> and <a href="http://sw.opencyc.org/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> has a tangible (i.e. material) part and a temporal extent (i.e. it exists in time). It might or might not also have an intangible part. For example, a particular copy of a book is made of matter, has temporal extent, and also has an intangible part: the information content of the text markings on its pages. tangible thing PartiallyTangible Wikipedia Article URL (<a href="http://sw.opencyc.org/concept/Mx4rNv0nbm4TTjOp7yhmnzOyqg" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article located at URL wikipediaArticleURL A collection of attributes of orbits for particular instances of satellites, <a href="http://sw.opencyc.org/concept/Mx4rdEVYXHSuEdaAAACgyZzFrg" class="cyc_term">OrbitalPathClass</a>es are determined by a satellite's distance from the surface of the earth (altitude).
