Given it's distance from the Sun, 30.1 UA, it receive very little light. 
It amount to 1/906 what you get from earth, and it's surface is 14.98 
that of the Earth.
One UA been the average distance from the Sun to the Earth.

It thus receive 0.0165 times the light received by the Earth over it's 
whole surface.

It's albedo is 0.29, compared to 0.367 for the Earth, making it darker.
It's total surface illuminate as 0.013065 (1.3%) Earth.

So, you'll probably see most of the stars down to a magnitude around 8.
