space engine是一個怎樣的軟體？裡邊的數據哪些是真實的？

比如行星的軌跡，大小，溫度，還有別的上邊的的影像、

一個帶你去幾百光年外的行星看星空的軟體。帶你裝逼帶你飛，現在已經出到0.971版本，有了BGM感覺更贊。說不定能找到星際穿越的感覺。

（額，情不自禁發個微博，不要在意這些細節）
說正經的。。。。這個軟體在同行軟體中娛樂性更強一些，很適合科普。
看看官網上的解釋：

a free space simulation program that lets you explore the universe in
three dimensions, from planet Earth to the most distant galaxies. Areas
of the known universe are represented using actual astronomical data,
while regions uncharted by astronomy are generated procedurally.
Millions of galaxies, trillions of stars, countless planets - all
available for exploration. You can land any planet, moon or asteroid and
watch alien landscapes and celestial phenomena. You can even pilot
starships and atmospheric shuttles.

一個可以讓你在三維空間中探索宇宙的免費太空模擬程序，從地球到非常遙遠的星系。已知宇宙區域的數據源於真是天文數據，而那些天文學上未知的區域有程序自動生成。無數個星球 - 都可以探索。你可以著陸到任何一個星球，衛星或小行星，觀看外星風景與天文現象。也可以駕駛恆星際飛船和太空梭。

玩的時候懷疑是生成的，可以點一下information，看看是否有wiki上的介紹，很容易區分的。

遊戲設計人員也在官網中做出了回答：
Q: How many real objects are there in SpaceEngine, and how many are generated by the program?

A: The entire Hipparcos catalog of stars, as well as
all known extrasolar planets, over ten thousand galaxies, and all of the
most prominent objects in our Solar system are included. This adds up
to over 130 000 objects. As for procedural objects, there are more
galaxies and star systems in SE than exist in reality in all of the
observable universe.
