The planet that has an atmosphere that protects life from the Sun's radiation is Earth.

Here's why:

* Ozone Layer: Earth's atmosphere contains a layer of ozone (O3) that absorbs most of the Sun's harmful ultraviolet (UV) radiation.

* Magnetic Field: Earth has a strong magnetic field that deflects charged particles from the Sun, known as the solar wind. This helps protect us from radiation that could be lethal.

While other planets have atmospheres, none have the specific combination of ozone and a magnetic field that provides the same level of protection as Earth's atmosphere.
