# AstronomicalData not including units?

I like using mathematica to do my physics homework, and AstronomicalData is useful for that, but it doesn't seem to work properly with units.

[the question is, at what height is the gravitational acceleration 4.9 meters per second square

Is there a way to get AstronomicalData to output with units?

You should post actual code, not images. – Sektor Apr 4 '14 at 14:57
If I were your teacher, I would frown on the large amount of data you "consume", and would appreciate a lean and mean Solve[9.81*r^2 == 4.9*(r + \[Delta])^2, \[Delta]] which results in {\[Delta]->0.414935 r} as positive solution. So 141.49% of earth's radius. But then again, tastes differ. – Wouter Apr 4 '14 at 15:19
AstronomicalData is older than the units. But, from what we can see in the new WL documentation, they will start coming with units. – Rojolalalalalalalalalalalalala Apr 4 '14 at 15:26

m = Quantity[AstronomicalData["Earth", "Mass"], AstronomicalData["Earth", "Mass", "Units"]]

5.9721986*10^24 kg

m // FullForm

Quantity[5.97219859999999999999999999999999999999992028.*^24,"Kilograms"]
