What is Halley?
Halley is a free software for management and working with the regularly updated database of comets, containing Keplerian orbital elements, non-gravitational and physical parameters of the comets and other data. The tasks performed by Halley software, in addition to database management, include calculation of the orbital evolution of small-bodies and visualization of their dynamics, detection of close approaches with the major planets in a given time interval, as well as a number of other tasks.
Regularly updated database of comets
Fast Search of comets by any element
High Speed and Precision
High-speed integration of the equations of motion and high-precision calculation of small-bodies orbits
And more features
Complete database management with possibility of adding your own objects, visualization of small-bodies orbits, calculation of orbital evolution, moments of perihelion passages, close approaches and more.
