For example, <code>TERM2</code> is, in the relevant sense, broader than <code>TERM1</code> if any of the following hold: <code>TERM2</code> is a collection that subsumes <code>TERM1</code>; <code>TERM2</code> is a collection that has <code>TERM1</code> as an instance; <code>TERM2</code> is a collection, instances of which have instances of the collection <code>TERM1</code> as parts; <code>TERM2</code> has <code>TERM1</code> as a part; This list of reasons for why <code>(<a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> could hold is not exhaustive, but it should give a good indication of how general the <a href="http://sw.opencyc.org/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> relation actually is. celestial object A specialization of both <a href="http://sw.opencyc.org/concept/Mx4r-n4BEPzcQdaYSaNf0XKNIw" class="cyc_term">CelestialObject</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVikt5wpEbGdrcN5Y29ycA" class="cyc_term">AstronomicalBody</a> (qq.v.).

In other words, celestial bodies are astronomical bodies that can be seen in the heavens from the surface of the Earth without the aid of artificial optical instruments.
