M.P.E.C. 2021-D62 Issued 2021 February 19, 18:47 UT The Minor Planet Electronic Circulars contain information on unusual minor planets and routine data on comets. They are published on behalf of Division F of the International Astronomical Union by the Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. Prepared using the Tamkin Foundation Computer Network MPC@CFA.HARVARD.EDU URL https://www.minorplanetcenter.net/ ISSN 1523-6714 DELETION OF 2020 SO The designation 2020 SO, announced on MPEC 2020-S78 and published in MPS 1245724, is being deleted. Based on its orbital evolution Paul Chodas suggested that 2020 SO could be the Centaur upper stage for the Surveyor 2 mission (1966-84B), launched on September 20, 1966. Subsequent observations revealed a large area to mass ratio of the object supporting the artificial nature of the object. The object was temporarily captured on geocentric orbit and will leave the Earths Hill sphere in March 2021. M. P. C. Staff (C) Copyright 2021 MPC M.P.E.C. 2021-D62
