Full-featured astronomy application for all UNIX-like systems
XEphem is a feature-rich scientific-grade interactive astronomical ephemeris package.
XEphem is cross-platform and it works on Mac OS X, Windows and Linux.
- computes heliocentric, geocentric and topocentric information for all objects;
- has built-in support for all planets; the moons of Mars, Jupiter, Saturn, Uranus and Earth; central meridian longitude of Mars and Jupiter; Saturn's rings; and Jupiter's Great Red Spot;
- allows user-defined objects including stars, deepsky objects, asteroids, comets and Earth satellites.
- provides special efficient handling of large catalogs including Tycho, Hipparcos, GSC.
- displays data in configurable tabular formats in conjunction with several interactive graphical views;
- displays a night-at-a-glance 24 hour graphic showing when any selected objects are up;
- displays 3-D stereo Solar System views that are particularly well suited for visualizing comet trajectories;
- quickly finds all close pairs of objects in the sky;
- sorts and prints all catalogs with very flexible criteria for creating custom observing lists;
- creates plots of any pairs of all data fields throughout the program;
- downloads current asteroid and comets ephemerides from Lowell Observatory and Minor Planet Center;
- downloads timely Earth satellite orbital TLE parameters;
- plots true binary system orbits;
- downloads Digitized Sky Survey FITS files from STScI or ESO;
- provides a handy coordinates spreadsheet for converting among equatorial, ecliptic, horizon and galactic frames ;
- displays live SOHO images of the Sun;
- includes a compiler for entering and solving user-written functions using any data fields;
- serves as the control point for GOTO telescopes such as Meade LX200 or other external applications;
- displays FITS files images overlaid with database symbols and other graphical information;
- performs automatic star pattern matching to automatically solve for World Coordinate System on any image;
- performs 1-click 2D Gaussian relative and absolute photometry;
- defines and saves any number of Eyepieces to use in sky maps;
- captures, displays and clips to any number of local horizon profiles;
- stores sets of all Sky View options in history sets for easy playback later;
- prints using high quality Postscript;
- allows you to assign any number of objects as Favorites for special fast access throughout the program, and makes them available even when their original databases are no longer loaded;
- provides an extensible image gallery initialized with over 300 beautiful and informative color images of deep sky objects;
- provides an observing logbook which is automatically filled in with observing circumstances, with searching on most fields;
- displays magnetic deviation for any location.
- create movie loops of any View, NAAG or Plot window.
