AstroGrav 是一个功能齐全、高精度的太阳系模拟器，用于计算所有天体之间的引力相互作用，因此与天文馆应用更精确地模拟小行星和彗星的运动。 可以考虑一般相对论和辐射压力的影响，而出色的交互式 3D 观看功能使您能够在太阳系发展时轻松旋转和缩放视图。 AstroGrav 软件具有广泛的功能和查看选项，包括来自空间或任何物体的视图、来自地球上任何位置的天文馆式视图、同时设置动画的多个视图、动态计算的轨道和轨迹、全面的表格数据以及从几分之一秒到数千年的模拟时间步长。 包括星座和超过100，000个背景恒星，每颗恒星都有全面的数据。 有几个不同的天体坐标网格和广泛的物理单元可用，编辑设施允许您手动创建新对象，或从数十万颗小行星和彗星导入。 因为它计算了天体的引力相互作用的运动，因此，Astrograv并不仅限于太阳系。 任何重力是唯一的重要力可以模拟的情况，AstroGrav 中包含的说明性样本文件包括许多示例，如系外行星系统、进化成行星系统的原行星、碎石堆及其与海量体、复杂恒星系统，甚至弹丸和弹跳球。 AstroGrav 是天文学家、天体物理学家、研究人员、教师、教育家和学生的的理想之选，并配有教程和完整的文档。 一个功能齐全的15天试用版可供下载和评估。
