Aero-Terms are designed to be a daily reminder of the terms,
names, acronyms and explanations of the unique language that
populates the aviation world. Aerospace, sport aviation, fixed
wing, helo, you name it... it's all fair game.
Aero-Terms should serve as a quick but intriguing reminder of
the terms you may use every day, or an introduction to an aspects
of the Aero-World you may not yet be familiar with. ANN also
encourages readers to go beyond the FMI link, and further research
any intriguing terms.
The lob-sided emission of radiation from a rotating object
orbiting the Sun, due to uneven heating; named after the Russian
engineer I. O. Yarkovsky, who first proposed the idea around 1900.
Among other things, it has been used to explain why Earth is hit
surprisingly often by meteorites. The uneven heating of a small
rock in the asteroid belt by the Sun, which makes the day side
warmer than the night side, creates a small force - enough to
deflect the object into one of the resonance zones where the
combined effect of Jupiter and Saturn's gravity pulls kick objects
into the inner solar system. Combined with other, less subtle
methods for getting fragments Earth-bound, including asteroid
impacts, the newly-proved method appears to account for the total
yearly shower of space rocks.
