In 1993 the spacecraft Galileo sent home an image (the figure) of asteroid 243 Ida and a tiny orbiting moon (now known as Dactyl), the first confirmed example of an asteroid–moon system. In the image, the moon, which is 1.5 km wide, is 100 km from the center of the asteroid, which is 55 km long. The shape of the moon's orbit is not well known; assume it is circular with a period of 27 h. (a) What is the...

In 1993 the spacecraft Galileo sent home an image of
asteroid 243 Ida and a tiny orbiting moon, now known as Dactyl.
This was the first example of an asteroid-moon system. The
moon is only about 1.5 km wide and Ida is about 55 km long. The
orbit of Dactyl is not well known, however it can be used to make
an estimate of Ida’s mass. (a) If we assume that
Dactyl’s orbit is circular, with a radius of 87...

In 1993 the spacecraft Galileo sent home an image of asteroid 243 Ida and an orbiting tiny moon (now known as Dactyl), the first confirmed example of an asteroid moon system. Other such systems have since been discovered. Assume an asteroid's moon is 1.6 km wide, and that its center is 116 km from the center of the asteroid, which is 55 km long. The moon's orbit is circular with a period of 24 h. (a) What is the mass...

On February 7, 1999, NASA
launched a spacecraft with the ambitious mission of making a close
encounter with a comet, collecting samples from its tail, and
returning the samples to Earth for analysis. This spacecraft,
appropriately named Stardust, took almost five years to
rendezvous with its objective-comet Wild 2 (pronounced "Vilt
2")-and another two years to return its samples. The reason for the
long round trip is that the spacecraft had to make three orbits
around the Sun, and also...
