Orbit Xplorer
$25 - ottisoft.com

Educational orbit and gravitation simulator for high school, college and beginning university physics and astronomy. Input mass, radius, coordinates and velocity components of 2 to 10 bodies manually or by dragging and dropping predefined bodies. Then watch how the orbits evolve under the mutual gravitaional attractions. Save and print the simulation.

Great for 'lab exercises' in gravitational physics or for verifying numerical answers to textbook problems. Includes 29 introductory to advanced premade simulations with activities page in html-format. Simulations include elliptical satellite orbits, Kepler's laws, double star, geocentric and heliocentric world view, Lagrange points, gravity assist, Hohmann orbit, extrasolar planet, inner solar system. Uses actual pictures of planets.

Plot orbits in a plane or in 3D. View time, distances, speeds, accelerations, energies and acceleration vectors as they change. Adjust the simulation speed to fit your computer. Zoom and change parameters during the simulation. Run up to four simultaneous simulations.

Tutorial and context-sensitive help included.

Coeli - Stella 2000
$49 - Coeli Software Products

Complete astronomy suite comprising a full-featured planetarium, observing log and list builder, Coeli Time Line, Live Orbits (orrery), location browser, Sky Quiz, and sophisticated searches embracing planets, comets, asteroids, DSOs, and up to 300,000 stars.

Planetarium effects include scintillation, extinction, refraction, and precession in point source, photo plate and spotlight display styles; along with the complete Messier catalog in image icons.

An integral HTML guide to the solar system, a 1000-term astronomical dictionary, and the 2nd revised and enlarged edition of Aspects of Astronomy -- a book-length primer covering topics such as "What are the Stars?", "Choosing a Telescope", "Cosmology", "Dark Matter", "Eclipses", and "The History of Astronomy", to name but a few -- are closely coordinated with the sky display and picture windows.

Stella 2000 talks and teaches aloud. With complete incorporation of Microsoft Agent speech technology, animated characters guide you painlessly through the pronunciation of a myriad of arcane star names and lore, and even read aloud from Astrogloss and Aspects of Astronomy, not to mention offering that most immediate form of program help: spoken guidance.

Stella's Drag Mode brings complete plasticity into all your interactions with the planetarium display. Dragging the mouse auto-scrolls sky quadrants smoothly and quickly into view from three selectable planes of reference: Horizon (local), Equatorial (atlas), and Ecliptic / Heliocentric. Stella provides direct links to extensive DSO and planetary information on the Web, all tightly unified with the Sky display, Reports, and the Coeli Solar Guide.

Auto-Search instantly updates readouts and reports on any object your mouse pointer scrolls over. You may even slew your Meade ETX/LX200 telescope to the object selected in Stella's sky.

MaterialWorlds Simulations
$19.95 - MaterialWorlds

Live interactive physics simulations let you explore the Solar System (orbits, seasons, gravity, tides, satellites and comets), play snooker (on a full size table) and experiment with Laws of Motion simulations (free worksheets provided for pendulum, Newtons cradle, terminal velocity and Galileos balls - as dropped from the Leaning Tower of Pisa) - latest release includes machines ( pendulum clock and siege engines) bridge, crash and ideal gas simulations and experiments. With real-time visualisation of forces and velocities (as arrows on each object as they interact or are pulled around with the mouse) and scrolling graphs recording what happens, MaterialWorlds gives a real feel for how the physical world works.
