جسم معتم يدور حول نجم، وكتلته كبيرة بالشكل الكافي حتى تُعطي جاذبيته القدرة على جعله كروي الشكل. يدور الكوكب في مدارٍ غير متقاطع مع أي كوكب آخر. كما أنه ليس كبيراً بما يكفي ليقوم بالإندماج النووي الذي تقوم به النجوم. الكواكب الأربعة الداخلية للمجموعة الشمسية هي كواكب صخرية بينما الأربعة الخارجية هي كواكب غازية
