It can't hold an atmosphere.  Atmospheric retention is based on escape velocity, not on surface gravity.

For those who want the math:

First, escape velocity [Calculator][1]: 5.98 km/sec

Second, to convert this to what can be held:

Light molecules such as any hydrogen-bearing one are soon lost.  This world holds an atmosphere about as well as Mars--and note what it's like there.
