AstroGrav 是一個功能齊全、高精度的太陽系模擬器，用於計算所有天體之間的引力相互作用，因此與天文館應用更精確地類比小行星和彗星的運動。 可以考慮一般相對論和輻射壓力的影響，而出色的互動式 3D 觀看功能使您能夠在太陽系發展時輕鬆旋轉和縮放視圖。 AstroGrav 軟體具有廣泛的功能和查看選項，包括來自空間或任何物體的視圖、來自地球上任何位置的天文館式視圖、同時設置動畫的多個檢視、動態計算的軌道和軌跡、全面的表格數據以及從幾分之一秒到數千年的類比時間步長。 包括星座和超過100，000個背景恆星，每顆恆星都有全面的數據。 有幾個不同的天體座標格格和廣泛的物理單元可用，編輯設施允許您手動創建新物件，或從數十萬顆小行星和彗星導入。 因為它計算了天體的引力相互作用的運動，因此，Astrograv並不僅限於太陽系。 任何重力是唯一的重要力可以模擬的情況，AstroGrav 中包含的說明性樣本檔包括許多示例，如系外行星系統、進化成行星系統的原行星、碎石堆及其與海量體、複雜恆星系統，甚至彈丸和彈跳球。 AstroGrav 是天文學家、天體物理學家、研究人員、教師、教育家和學生的的理想之選，並配有教程和完整的文檔。 一個功能齊全的15天試用版可供下載和評估。
