Is my planet realistic?

Is my planet realistic? It doesn't need to be able to support life as it's just another planet in my solar system, but is a planet with such a high density and gravity really possible? I calculated the density and gravity with the following equation:
$$\text{Gravity} = \frac{\text{Mass}}{\text{Radius}^2}$$
$$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$$
And these are the values for my planet:
Mass - 0.4 Earth masses
Radius - 0.3 Earth radius
Gravity - 4.44 Earth gravity
Density - 3.54 Earth density
