4923 Clarke, provisional designation 1981 EO27, is a stony background
5020 Asimov
.
Orbit and classification
Clarke is a non-
semi-major axis of 2.14 AU). Its orbit has an eccentricity of 0.20 and an inclination of 7° with respect to the ecliptic.[2]
The asteroid was first observed as 1972 NJ at
Crimea–Nauchnij in July 1972. The body's observation arc begins at the Siding Spring Observatory two weeks prior to its official discovery observation on 12 February 1981.[1]

Diameter and albedo
According to the survey carried out by the
albedo between 0.3259 and 0.366.[4][5] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.20 and calculates a diameter of 4.10 kilometers based on an absolute magnitude of 14.3.[6]

In the postscript to his novel 3001: The Final Odyssey, Clarke jokingly expresses disappointment that he did not receive asteroid 2001 as his namesake; instead, it was named for Albert Einstein.[citation needed]
