Star systems of all types now have motion based on Keplerian orbital data within a system. The motion of binaries, ternaries, and above are all simulated including black hole - star binaries (see Cygnus X-3) which tend to have the fastest orbits or the triple star Algol (90 Ly). Complex orbital motion is also modeled such as Rigel's (732.9 Ly) 4 stars where star C orbits Rigel A, Ba orbits C, and Bb orbits Ba.

Stars are all organized in the same fashion as the data, two stars one being a primary and one a companion. Note that currently you can only transition from companion star to primary while motion is running.

• Star orbital motion added for 2 or more star systems.
  
• Performance optimization during motion.
  
• Smoother transitions from object to object while motion is running.
  
• Updated time control to give a greater range.
  

• Orbital data, especially semi-major axis has been reviewed and corrected.
  
• Brief flash fixed when going to a distant star from the Selection menu.
  
• Far orbit planet stuttering (when viewed from a moon, e.g. Charon to Pluto) has been fixed.
