investigate the possibility of detecting the Yarkovsky effect via precise orbit determination of the near-earth asteroids on example of the asteroids 6489 Golevka, 1620 Geographos
, 1566 Icarus, and 1998 KY26 with different values of the parameter da/dt.
Este oblicuo encarecimiento de la experiencia empirica por encima de la filosofia clasica recuerda la actitud del humanista Antonio de Torquemada, quien, en el tractado V de su Jardin de flores curiosas (Salamanca, 1570), afirma con elocuente clarividencia que los antiguos "estuvieron enganados", ya que "aunque fueron grandes cosmographos o geographos
For example, the Earth-crossing asteroid 1620 Geographos
gets trapped temporarily in a number of resonances with Earth in the course of its chaotic evolution (Fig.
The asteroids' irregular shapes give each something resembling a personality: Kleopatra is shaped like a dog bone, Eros like a rutabaga, Geographos
like a turd.
The mission called for the probe to orbit the moon for over two months and then depart the cislunar region for a rendezvous with the asteroid Geographos
McCarthy earned the number 932 after WCCSAS member Miskie submitted precise positions of the Earth-approaching asteroid 1620 Geographos
to the IAU's Minor Planet Center in late February.
Not quite, but the Clementine spacecraft isn't likely to keep an August date with the near-Earth asteroid 1620 Geographos
It was Nozette who in 1989 talked the Ballistic Missile Defense Organization into using its Star Wars technology to reconnoiter the Moon and then fly off to "attack" asteroid 1620 Geographos
. Conceived on the back of a cocktail napkin, the high-risk, no-frills Clementine craft proved spectacularly successful in lunar orbit (S&T: August 1994, page 20).
That body, a 20-km-wide asteroid known as 1620 Geographos
, lies only twice as far from Earth as the moon.
During a dress rehearsal for a planned flyby of minor planet 1620 Geographos
the spacecraft opened four of its attitude-control thrusters and mistakenly let them fire for 11 minutes -- until the steering gas ran out.
