Why can I sometimes see low-lit objects better with my peripheral vision as opposed to when I directly look at said object?

I'm thinking of looking at objects like stars at night - sometimes I feel like some stars are brighter in my peripheral than they are when I directly look at them.

Your eyes consist of two types of receptors called rods and cones. 
Cones are good for high detailed and colour visual perception while rods are good better to detect movement especially in low light. 
There's usually more rod receptors in your peripherals.
