4587 Rees is an Amor asteroid discovered on September 30, 1973 at the Palomar Observatory by Cornelis Johannes van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels. The Provisional designation given to 4587 Rees was 3239 T-2. It has a rotation period of 7.7886 hours.〔 4587 Rees was named in honor of Martin Rees. Naming it after Professor Lord Rees was proposed by Jan Hendrik Oort. On 2072-Jul-03 Rees will pass from Mars, the closest since it passed from Mars on 1843-Jan-28. On 2121-Jan-30, Rees will pass from 4 Vesta.〔 == NEO status == Since all Near-Earth objects (NEOs) have a closest approach to the Sun (perihelion) of less than 1.3 AU,〔 depending on the epoch chosen, the orbital parameters of 4587 Rees will not always qualify it as a NEO. For example, in the year 2014 Rees will have a perihelion of 1.3011 AU and will not meet the requirement to be defined as a NEO.〔
