ON THE WEB
Published papers

Most published papers in astronomy can be
found on the NASA Astrophysics Data System:
http://adswww.harvard.edu/
ADS

To access the most recent papers in some
journals you will need a subscription to them, or
access them from an institution that has a
subscription
Preprints


These are papers posted on the web before they
have been published in a journal
Many preprints are posted on astro-ph:

No subscription is needed to access these
preprints.

If you want, you can have the astro-ph website
send you daily the list of new preprints posted

Solar System Ephemerides

JPL Horizons On-Line Ephemeris System

The JPL Horizons On-Line Ephemeris System provides easy
access to key solar system data and flexible production of highly
accurate ephemerides for solar system objects. This includes
170,000+ asteroids & comets, 128 natural satellites, 9 planets, the
Sun, select spacecraft, and several dynamical points such as
Earth-Sun L1, L2 and system barycenters. Users may define their
own objects, then use the system to integrate the trajectory, or
conduct parameter searches of the comet/asteroid database,
searching on combinations of up to 42 different parameters.
Rise, transit and set may be identified to the nearest minute.
Close-approaches by asteroids and comets to planetary bodies
(and Ceres, Pallas, and Vesta) can be easily identified. Orbit
uncertainties can be computed for asteroids and comets.
