does it give out any radiation?
From the core out to about 0.7 solar radii, thermal radiation is the primary means of energy transfer.

what makes uranus move at such a slow speed UNANSWERABLE what is this planetary body? It is the seventh planet from the Sun. who was the first to identify it? Possibly the earliest known observation was by Hipparchos. where did it get its name from? It's name references the ancient Greek deity of the sky Uranus. how hot is the interior of it? It's internal heat appears markedly lower than that of the other giant planets what is the size of the star mentioned above that it revolves around? Its diameter is about 109 times that of Earth.

Sun [SEP] Radiative zone
From the core out to about 0.7 solar radii, thermal radiation is the primary means of energy transfer. The temperature drops from approximately 7 million to 2 million kelvins with increasing distance from the core. This temperature gradient is less than the value of the adiabatic lapse rate and hence cannot drive convection, which explains why the transfer of energy through this zone is by radiation instead of thermal convection. Ions of hydrogen and helium emit photons, which travel only a brief distance before being reabsorbed by other ions. The density drops a hundredfold (from 20 g/cm to 0.2 g/cm) from 0.25 solar radii to the 0.7 radii, the top of the radiative zone.
