Global informations about the Earth (such as its mass and its moment of inertia) can be extracted  from gravitational measurements. Propagation of seismic waves allow us to infer properties of the  crust, the mantle and the outer core. The inner core, however, cannot be tested directly, as seismic  waves cannot cross the liquid outer  core. Neutrinos can be used to measure the Earth's density profile by  means of electroweak  interactions only, thus giving an independent  and complementary  picture of the Earth. I will show the first sensitive neutrino Earth tomography result to date using one year of IceCube atmospheric neutrinos data, and discuss the future prospects.
