Spacecraft

This property can be used for a spacecraft? Eg: Q217543 --Adert (talk) 18:11, 30 April 2016 (UTC)

I think it can. -- Innocent bystander (talk) 06:32, 30 May 2016 (UTC)

Units

@ValterVB: The units in the constraints looks a little strange to me. I expected time-units here, like day (Q573), years, minutes. Was your edit a mistake or did I miss something? -- Innocent bystander (talk) 06:30, 30 May 2016 (UTC)

{ping|Innocent bystander}} It was a copy/paste error, thanks --ValterVB (talk) 16:56, 30 May 2016 (UTC)

@ValterVB: I Think we should add "year" as well (for far distant objects of the solar system: see Q1932426). --Ysogo (talk) 22:36, 14 January 2019 (UTC)

@Ysogo:  Done --ValterVB (talk) 08:14, 20 January 2019 (UTC)
