Summarize this article for a 10 year old
2006 RH120 is a tiny near-Earth asteroid[9] and fast rotator with a diameter of approximately 2–3 meters[7] that ordinarily orbits the Sun but makes close approaches to the Earth–Moon system around every twenty years,[10] when it can temporarily enter Earth orbit through temporary satellite capture (TSC). Most recently, it was in Earth orbit from July 2006 to July 2007,[11] during which time it was never more than 0.0116 AU (1.74 million km) from Earth.[12] As a consequence of its temporary orbit around the Earth, it is currently the second smallest asteroid in the Solar System with a well-known orbit, after 2021 GM1. Until given a minor planet designation on 18 February 2008,[1] the object was known as 6R10DB9, an internal identification number assigned by the Catalina Sky Survey.[8]
