Database Updates
Our view of the universe will change over
the next ten years. New moons will be
discovered, bright new comets will streak
towards the Sun, and new satellites will be
launched into orbit. To ensure that Starry
Night’s library of data keeps up with these
changes, several update mechanisms are
built into the program.
The databases of comets, asteroids and
satellites change more frequently than
other databases, so Starry Night has a
special method of updating these
databases. Choose LiveSky->Update
Comets/Asteroids/Satellites and updated
satellite, comet and asteroid data files will
be downloaded from our website. We
update these files several times a week, so
you can expect that any new comets,
asteroids or satellites will be added as soon
