The Yarkovsky–O'Keefe–Radzievskii–Paddack effect, or YORP effect for short, changes the rotation state of a small astronomical body – that is, the body's spin rate and the obliquity of its pole(s) – due to the scattering of solar radiation off its …

The 'YORP effect' is short for the 'Yarkovsky-O'Keefe-Radzievskii-Paddack effect', named for the four researchers who proposed various aspects of it.

Dec 6, 2017 · Online YORP Registration is back! Following the approval of its guidelines at the seventh Regular Commissioners' Meeting, the online registration platform for the Youth Organization Registration Program (YORP) has been re-launched and is now up at yorpnyc.org.ph/register.php.

Dec 11, 2014 · Understanding the Yarkovsky Effect is essential to determine the impact probability. The YORP effect is a similar phenomenon that affects the rotation rate and pole orientation of an asteroid. YORP is an acronym that combines four scientist’s names: Yarkovsky, O’Keefe, Radzievskii, and Paddack.

Mar 22, 2024 · The YORP Effect, short for Yarkovsky-O’Keefe-Radzievskii-Paddack Effect, is a phenomenon that affects the rotation rate and orientation of asteroids in space. It is caused by the uneven heating of an asteroid’s surface by the Sun, which in turn creates a torque that can alter the asteroid’s spin.

Studying astronomy? You'll need to know about the Yarkovsky and YORP effects. Read on for my full explanation of these hidden forces and their consequences in astronomy.

Sep 26, 2022 · Definition of the YORP Effect: In astrophysics, the YORP effect is what happens when reflected and/or absorbed sunlight generates “thermal torque” on an asteroid. Reflected sunlight exerts a very small (but non-zero) amount of force on the surface of an asteroid.

During the past decade or so, the Yarkovsky and YORP effects have been used to explore and potentially resolve a number of unsolved mysteries in planetary science dealing with small bodies. Here we review the main results to date, and preview the goals for future work. 1. INTRODUCTION.

Aug 22, 2018 · The YORP effect is when the thrust produces rotation, likely due to uneven heating or differences in surface projections (IE: A mountain acts as a better solar collector than a flatter portion of a spherical object on the opposite side).
