A '''planet''' is an astronomical body that is in [[orbit]] around a [[star]], that 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 does 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.
