80 Starry Night User’s Guide
Introduction to Databases
Starry Night includes literally millions of
celestial objects, from dozens of different
databases.
Accessing Databases: As you learned in
chapter 3, “Appearance of the Sky
”, you
can use the Options side pane to turn
databases on/off, turn their labels on/off,
or modify the database display options. All
of these functions can also be accessed
from the main menu, by choosing View,
Labels, or Options, respectively.
We’ll now briefly describe each of the
databases included in Starry Night. The
databases in your version of Starry Night
may be slightly different from those listed
here, as we are continually updating and
adding new databases. As you learned in
“Options Pane
” on page 34, databases are
organized in a layered framework, based
on their distance from Earth.
The three major database layers are:
1 Solar System
2 Stars
3 Deep Space
Databases 1 (Solar System)
These databases are for objects that are
inside our solar system.
Satellites: This refers to any man-made
body orbiting our Earth. Most satellites
fall into two distinct types of orbits:
near-Earth orbits or geosynchronous
orbits. Satellites in near-Earth orbit move
much more rapidly than Earth rotates, so
they move over a large slice of the Earth’s
surface. Geosynchronous satellites are
much farther from Earth. They move at
exactly the same speed as Earth rotates, so
they stay directly above the same point on
Earth’s surface at all times. Starry Night
includes about 150 satellites. Satellite data
needs to be updated regularly. See
“Database Updates
” on page 85 for
information on updating satellite data.
Meteor Showers: This database marks the
positions of the major meteor shower
radiants. The radiant is the point in the sky
where all meteors from a given meteor
shower appear to be coming from. Meteor
showers are formed by comets that come
close to the Sun. Heat from the Sun causes
dust and rock to break off the comet and
gather into a collection of debris that
moves along the comet’s orbital path. If
Earth’s orbit crosses this path, there is a
meteor shower as the dust particles burn
up in Earth’s atmosphere. Each meteor
shower happens at about the same time
each year. This database uses data from the
International Meteor Organization and was
created by Stephen Hutson.
Asteroids: Small, rocky bodies that are too
small to be planets. Most asteroids lie in
the “asteroid belt”, a region of space
between the orbits of Mars and Jupiter.
Asteroid data needs to be updated
regularly. See “Database Updates
” on
page 85 for information on updating
asteroid data.
Comets: These are the small balls of rock
and ice which revolve around the sun.
Comets have very elliptical orbits,
meaning their distance from the sun varies
greatly with time. Comets are usually far
away from the Sun, out beyond the orbit of
