SB What's Observable
This tool provides a list of small-bodies only (asteroids and/or comets)
which are optically observable from the specified location
on the night of the specified date/time
with the specified observing constraints satisfied.

This tool uses two-body dynamics to propagate asteroid and comet
positions from their orbit solution epoch to the requested observing time.
For most asteroids, this approximate solution is reasonably accurate.
However, for some asteroids and most comets,
if the observation time is on the order of a few years or more from its orbital epoch,
the error in the approximate position can be significant.
Use our HORIZONS
system to generate precise ephemerides to verify individual object
results as necessary.
