The 'Age' parameter is ignored in a script in the 'catalogs\stars' directory. So probably some other data.Also, I found possible age error in the stellar system HD 164922 as compared in SE 0.980 with that of Wikipedia:
Stellar parameters: Space Engine 0.980 Wikipedia
Spectrum G9-V G9-V
Diameter 0.999 Solar Diameter 0.999 Solar Diameter
Mass 0.874 Solar Mass 0.874 Solar Mass
Luminosity 0.65157 0.703

"This star is metal-rich, with a metallicity of 0.16, or 144% the solar amount. This is particularly odd for a star as old as HD 164922."
https://en.wikipedia.org/wiki/HD_164922 This stellar system has two gaseous giant Jupiters much older by several billion years than the other systems such as Kapteyn's Star 11.31 GA, Kepler-444 12.22 GA, and PSR B1620-26 12.62 GA, all of which are true ages in SE. The age of our Universe is close to 13.82 GA. There is contested claim for the oldest star BD +17 3248 as 13.8 GA and with extreme poor metallicity. I thought everyone in the SE forum is welcome to report any possible errors in the star system data or even exoplanet data. Thank you again.

The problem is the radius of the planet, 94322655 Km! With this size it would have to be a star. And a rather big one.I have many reasons to believe the planet KOI-4034.02 is bugged. It has an mass that's NaN, a height that's NaN, a diameter of 1.26 AU, and a lot more buggy things. This is also present in 0.980.
