(provisional designation ; also known as ) is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4km (00.9miles) in diameter. It was discovered on 17 May 2010 by the Wide-field Infrared Survey Explorer (WISE) satellite, but was lost until it was reobserved on 16 January 2016. With an observation arc over 11 years, has a well-determined orbit and trajectory through the year 2086. The asteroid's orbit is only potentially hazardous on a time scale of thousands of years.
On 21 August 2021, the asteroid safely made a close approach to Earth from a distance of 0.0229AU, or 8.92 lunar distances (LD). During closest approach, reached a peak apparent magnitude of 14, visible to ground-based observers with telescope apertures of at least . It is the largest asteroid that approached within 10LD of Earth in 2021.
The asteroid received the permanent minor planet number 620094 by the Minor Planet Center on 7 April 2023.
