[AstroPy] Where is the cache file de430.bsp in local machine?

[Yang Hon-Jang]

First time I execute the script get_body('sun', t,  ephemeris='jpl'),
I see following message：
Downloading
http://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/planets/de430.bsp
[Done]

But I can't locate the file de430.bsp in my local computer.
Where is it？
