from approximately 25 days at the equator to 36 days
at the poles. Deep down, below the convective zone,
everything appears to rotate with a period of 27 days.

If confirmed, S/1999 J 1 will become the smallest
known satellite of a major planet. Of course, there
are thousands of smaller asteroids, Kuiper Belt objects,
and comets.
There are 12 major bodies brighter than magnitude 6
(as viewed from Earth). All of these can be seen with
the unaided eye or with binoculars.

Name Why
--------- -------
Earth :-)
Mars most Earth-like; more so in the past; ALH84001
Europa may have liquid water
Enceladus may have liquid water
Titan complex chemistry and liquids likely
Io complex chemistry, warmer than most
Jupiter long shot: warm, plenty of organic material
The Mars meteor results notwithstanding, all of this
remains very speculative. None of these prospects are
really very good. Good arguments can be made why life
(at least life as we know it) cannot exist on any of
these bodies. (More speculation about life
on Europa and Enceladus.)
