Version 1.6.2 of AstroGrav has the following new and improved features.


Version 1.6.2 of AstroGrav includes an improvement to the way that evolution is indicated on the status line. Evolution is now indicated by an animated series of dots rather than a static text string, so that it is clear that AstroGrav is still working when the calculations are taking a long time and no screen updates are taking place.

Object Orbits

Version 1.6.2 of AstroGrav includes a correction to a fault that occasionally caused part of an orbit to be drawn as a straight line instead of as a curve. This fault was rarely seen, and only ever affected the drawing of orbits with an eccentricity slightly less than one. This fault has now been corrected, so that orbits are now drawn correctly in all circumstances.

Object Magnitudes

Version 1.6.2 of AstroGrav includes a correction to a fault that caused the magnitudes of objects to be displayed incorrectly. An incorrect constant had been used in the calculation of magnitudes that caused them to be displayed 0.096 magnitudes too bright. This fault has now been corrected, so that magnitudes will now be displayed 0.096 magnitudes dimmer than before.

Other Improvements

Version 1.6.2 of AstroGrav also has many other minor improvements and bug fixes, including the following.

  • The drawing of model windows has been significantly speeded up.
  • A bug has been fixed that sometimes caused a non-luminous object (such as a planet) to be invisible when in transit against a luminous object (such as the Sun).
  • The size that objects without auras are drawn has been slightly increased to make them more compatible with the corresponding objects drawn with auras.
  • There are some minor performance improvements.
  • Corrections have been made to some of the non-English translations.
