Planet-planet pengembara bisa jadi berasal dari sistem keplanetan tempat planet-planet tersebut terbentuk dan kemudian dilontarkan, atau bisa juga terbentuk dengan sendirinya di luar sistem keplanetan. [[Bima Sakti]] sendiri mungkin memiliki milyaran hingga triliunan planet pengembara, sebuah rentang yang mungkin bisa dipersempit oleh Teleskop Antariksa Nancy Grace Roman yang akan datang.<ref>{{Cite web|date=2014-03-13|title=A Guide to Lonely Planets in the Galaxy – Phenomena: No Place Like Home|url=https://web.archive.org/web/20140313190543/http://phenomena.nationalgeographic.com/2014/03/13/a-guide-to-lonely-planets-in-the-galaxy/|website=web.archive.org|access-date=2024-06-21}}</ref><ref>{{Cite web|last=Balzer|first=Ashley|last2=Center|first2=NASA’s Goddard Space Flight|date=2020-08-23|title=“Our Solar System May Be Unusual”: Rogue Planets Unveiled With NASA’s Roman Space Telescope|url=https://scitechdaily.com/our-solar-system-may-be-unusual-rogue-planets-unveiled-with-nasas-roman-space-telescope/|website=SciTechDaily|language=en-US|access-date=2024-06-21}}</ref>
 
Beberapa planet pengembara mungkin terbentuk dengan cara yang sama seperti bintang, dan [[Persatuan Astronomi Internasional]] mengusulkan agar objek semacam itu disebut "katai sub-cokelat".<ref>[http://www.dtm.ciw.edu/boss/definition.html Working Group on Extrasolar Planets – Definition of a "Planet"] Position Statement on the Definition of a "Planet" (IAU) {{Webarchive}}</ref> Contohnya adalah [[Cha 110913-773444]], yang mungkin terlempar dari sistem keplanetannya dan menjadi planet pengembara, atau terbentuk sendirian dan menjadi katai sub-cokelat.<ref name="CNN">[http://edition.cnn.com/2000/TECH/space/10/06/space.planets.reut/index.html Rogue planet find makes astronomers ponder theory]</ref>
