A '''planet''' is a astronomical body that is in [[orbit]] around a [[star]], has sufficient mass for its own [[gravity]] to overcome rigid body forces so that it assumes an approximately spherical shape, and has cleared the neighborhood around its orbit <ref>http://www.iau.org/iau0603.414.0.html</ref>.

A '''planet''' is a astronomical body that is in [[orbit]] around a [[star]], has sufficient mass for its own [[gravity]] to overcome rigid body forces, assumes an approximately spherical shape, and has cleared the neighborhood around its orbit <ref>http://www.iau.org/iau0603.414.0.html</ref>, i.e. has "swept out" the area around its orbit during its formation, accreting into its mass all other smaller bodies within its orbit. Consequently, a planet dooes not share its orbital region with any other bodies of significant size, except for its satellites or those collected later by virtue of its gravitational field.  

 

The phrase "cleared the neighborhood around its orbit" refers to a body "sweeping out" the area around its orbit as it forms, by causing all other smaller bodies in its orbit to accrete with it. As a consequence it does not then share its orbital region with any other bodies of significant size, except for satellites or those collected later under its gravitational influence.
