Editing YORP effect (section)

== Term ==
The term was coined by [[David P. Rubincam]] in 2000<ref>{{Cite journal |last=Rubincam |first=D |title=Radiative Spin-up and Spin-down of Small Asteroids |url=https://zenodo.org/record/1229840 |journal=Icarus |language=en |volume=148 |issue=1 |pages=2–11 |doi=10.1006/icar.2000.6485 |bibcode=2000Icar..148....2R |year=2000 |access-date=2019-12-11 |archive-date=2020-02-26 |archive-url=https://web.archive.org/web/20200226134341/https://zenodo.org/record/1229840 |url-status=live }}</ref> to honor four important contributors to the concepts behind the so-named YORP effect. In the 19th century, [[Ivan Osipovich Yarkovsky|Ivan Yarkovsky]] realized that the [[thermal radiation]] escaping from a body warmed by the Sun carries off [[momentum]] as well as [[heat]]. Translated into modern physics, each emitted [[photon]] possesses a momentum ''p'' = ''E/c'' where ''E'' is its [[energy]] and ''c'' is the [[speed of light]]. Vladimir Radzievskii applied the idea to rotation based on changes in [[astronomical albedo|albedo]]<ref>Radzievskii (1954)</ref> and Stephen Paddack realized that shape was a much more effective means of altering a body's spin rate.<ref>{{Cite journal|last=Paddack|first=S.

O'Keefe (astronomer)|John O'Keefe]] suggested that the YORP effect leads to rotational bursting and by repeatedly undergoing this process, small asymmetric bodies are eventually reduced to dust.<ref>S.
