[ noun ] the remains of something that has been destroyed or broken up

Used in print

(J. F. Vedder, "Micrometeorites", in Francis S. J...)

The Poynting-Robertson effect ( Robertson , 1937 ; Wyatt and Whipple , 1950 ) , which is a retardation of the orbital motion of particles by the relativistic aberration of the repulsive_force of the impinging solar_radiation , causes the dust to spiral into the sun in times much shorter than the age of the Earth .

Further , the corpuscular_radiation , i.e. , the solar_wind protons , must sputter away the surface atoms of the dust and cause a slow diminution in size , with a resultant increase in both the Poynting-Robertson effect and the ratio of the repulsive_force to the gravitational_force .

Also , planetary gravitational_attraction increases the dust concentration near the plane of the ecliptic as the sun is approached .

At one astronomical_unit from the sun ( the Earth 's distance ) the dust orbits are probably nearly circular .

It is also possible that some of the dust in the vicinity of the Earth originated from meteoritic impacts upon the moon .
